Question

我在C＃中收到一个JSON字符串，如下所示：

{
    "Id": "617723",
    "Acronym": "",
    "FirstName": "XXXXX",
    "LastName": "XXXXX",
    "Groupe": {
        "Code": "XXXXX",
        "Traductions": {
            "French": "",
            "English": "XXXXX"
        }
    },
    "BusinessUnit": {
        "Code": "XXXXX",
        "Traductions": {
            "French": "",
            "English": "XXXXX"
        }
    },
    "Team": {
        "Code": null,
        "Traductions": {
            "French": "",
            "English": null
        }
    },
    "Title": {
        "Code": null,
        "Traductions": {
            "French": "",
            "English": "XXXXX"
        }
    },
    "Title2": {
        "Code": null,
        "Traductions": {
            "French": "",
            "English": null
        }
    },
    "JobCategory": {
        "Code": "XXXXX",
        "Traductions": {
            "French": "",
            "English": "XXXXX"
        }
    },
    "PhoneList": [],
    "DateHired": "XXXXX",
    "DateTerminated": "XXXXX",
    "Gender": "XXXXX",
    "ManagerId": "XXXXX",
    "ManagerAcronym": "XXXXX",
    "IsManager": false,
    "Email": null,
    "CarLicense": null,
    "MyTeam": [],
    "HomeBase": {
        "Code": "XXXXX",
        "Traductions": {
            "French": "XXXXX",
            "English": "XXXXX"
        }
    },
    "Country": {
        "Code": "XXXXX",
        "Traductions": {
            "French": "XXXXXX",
            "English": "XXXXX"
        }
    },
    "State": {
        "Code": "XXXXX",
        "Traductions": {
            "French": "XXXXX",
            "English": "XXXXX"
        }
    },
    "City": {
        "Code": "XXXXX",
        "Traductions": {
            "French": "XXXXX",
            "English": "XXXXX"
        }
    },
    "ShirtSize": "",
    "LanguageAddressBook": "XXXXX",
    "LanguagePrefered": null,
    "Local": null,
    "Mailbox": null,
    "HomeBusinessUnit": "1",
    "JobType": "XXXXXX",
    "UnionCode": "",
    "ProfessionalTitle": {
        "Code": null,
        "Traductions": {
            "French": "",
            "English": null
        }
    },
    "IconEmailActif": true,
    "IconSkypeActif": true
}

我想在C＃对象中转换它，所以我将我的模型设为：

public class UsersJson
{
    public string Acronym { get; set; }

    public string[] BusinessUnit { get; set; }

    public string CarLicense { get; set; }

    public string[] City { get; set; }

    public string[] Country { get; set; }

    public string DateHired { get; set; }

    public string DateTerminated { get; set; }

    public string Email { get; set; }

    public string FirstName { get; set; }

    public string Gender { get; set; }

    public string[] Groupe { get; set; }

    public string[] HomeBase { get; set; }

    public string HomeBusinessUnit { get; set; }

    public bool IconEmailActif { get; set; }

    public bool IconSkypeActif { get; set; }

    public string Id { get; set; }

    public bool IsManager { get; set; }

    public string[] JobCategory { get; set; }

    public string JobType { get; set; }

    public string LanguageAddressBook { get; set; }

    public string LanguagePrefered { get; set; }

    public string LastName { get; set; }

    public string Local { get; set; }

    public string Mailbox { get; set; }

    public string ManagerAcronym { get; set; }

    public string ManagerId { get; set; }

    public string[] MyTeam { get; set; }

    public string[] PhoneList { get; set; }

    public string[] ProfessionalTitle { get; set; }

    public string ShirtSize { get; set; }

    public string[] State { get; set; }

    public string[] Team { get; set; }

    public string[] Title { get; set; }

    public string[] Title2 { get; set; }

    public string UnionCode { get; set; }
}

当我尝试将其反序列化为List<UsersJson>时，我收到以下错误：

无法将当前JSON对象（例如{\“name \”：\“value \”}）反序列化为类型'System.String []'，因为该类型需要JSON数组（例如[1,2,3] ）正确反序列化。要修复此错误，请将JSON更改为JSON数组（例如[1,2,3]）或更改反序列化类型，使其成为普通的.NET类型（例如，不是像整数这样的基本类型，而不是类似的集合类型可以从JSON对象反序列化的数组或List。 JsonObjectAttribute也可以添加到类型中以强制它从JSON对象反序列化。路径'[0] .Groupe.Code'，第1行，第87位。“

那么，如果属性Group不是string[]，我应该如何声明它？

Answer 1

使用正确的课程。我跟着steps outlined here并重构了一下：

RootObject r = JsonConvert.DeserializeObject<RootObject>(json);

public class Traductions
{
    public string French { get; set; }
    public string English { get; set; }
}

public class Groupe
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class BusinessUnit
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class Team
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class Title
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class JobCategory
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class HomeBase
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class Country
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class State
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class City
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class ProfessionalTitle
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class RootObject
{
    public string Id { get; set; }
    public string Acronym { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Groupe Groupe { get; set; }
    public BusinessUnit BusinessUnit { get; set; }
    public Team Team { get; set; }
    public Title Title { get; set; }
    public Title Title2 { get; set; }
    public JobCategory JobCategory { get; set; }
    public List<object> PhoneList { get; set; }
    public string DateHired { get; set; }
    public string DateTerminated { get; set; }
    public string Gender { get; set; }
    public string ManagerId { get; set; }
    public string ManagerAcronym { get; set; }
    public bool IsManager { get; set; }
    public string Email { get; set; }
    public string CarLicense { get; set; }
    public List<object> MyTeam { get; set; }
    public HomeBase HomeBase { get; set; }
    public Country Country { get; set; }
    public State State { get; set; }
    public City City { get; set; }
    public string ShirtSize { get; set; }
    public string LanguageAddressBook { get; set; }
    public string LanguagePrefered { get; set; }
    public string Local { get; set; }
    public string Mailbox { get; set; }
    public string HomeBusinessUnit { get; set; }
    public string JobType { get; set; }
    public string UnionCode { get; set; }
    public ProfessionalTitle ProfessionalTitle { get; set; }
    public bool IconEmailActif { get; set; }
    public bool IconSkypeActif { get; set; }
}

Answer 2

您需要使用Code和Traductions属性的其他几个课程。

public class Groupe {
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class Traductions {
    public string French { get; set; }
    public string English { get; set; }
}

在您的基类中使用Groupe代替string[]，您应该是金色的：）

Answer 3

接受的答案有效，但我觉得它有很多代码重复。您只需要另外两个模型类就可以了：

public class Traductions
{
    public string French { get; set; }
    public string English { get; set; }
}

public class CodeTraduction
{
    public string Code { get; set; }
    public Traductions Traductions { get; set; }
}

public class RootObject
{
    public string Id { get; set; }
    public string Acronym { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public CodeTraduction Groupe { get; set; }
    public CodeTraduction BusinessUnit { get; set; }
    public CodeTraduction Team { get; set; }
    public CodeTraduction Title { get; set; }
    public CodeTraduction Title2 { get; set; }
    public CodeTraduction JobCategory { get; set; }
    public List<object> PhoneList { get; set; }
    public string DateHired { get; set; }
    public string DateTerminated { get; set; }
    public string Gender { get; set; }
    public string ManagerId { get; set; }
    public string ManagerAcronym { get; set; }
    public bool IsManager { get; set; }
    public string Email { get; set; }
    public string CarLicense { get; set; }
    public List<object> MyTeam { get; set; }
    public CodeTraduction HomeBase { get; set; }
    public CodeTraduction Country { get; set; }
    public CodeTraduction State { get; set; }
    public CodeTraduction City { get; set; }
    public string ShirtSize { get; set; }
    public string LanguageAddressBook { get; set; }
    public string LanguagePrefered { get; set; }
    public string Local { get; set; }
    public string Mailbox { get; set; }
    public string HomeBusinessUnit { get; set; }
    public string JobType { get; set; }
    public string UnionCode { get; set; }
    public CodeTraduction ProfessionalTitle { get; set; }
    public bool IconEmailActif { get; set; }
    public bool IconSkypeActif { get; set; }
}

使用您的示例JSON，您可以将其反序列化为：

var item = JsonConvert.DeserializeObject<RootObject>(json);

如果愿意，您可以创建单独的类，但保留一个基类CodeTraduction，例如：

public class Groupe : CodeTraduction
{
    //Add any "Groupe" specific properties here
}

Answer 4

为了将来参考，您还可以使用“选择性粘贴”。您复制JSON文件（ Ctrl + C ）并添加新的类文件（如果您还没有）。然后你进入编辑（在VS的左上角）并将光标悬停在Paste Special上，你将得到两个选项，一个用于XML作为Class或JSON作为Class。希望它能在未来帮助您和其他人。：）
