Question

我在将一些c＃字段序列化为XML文件时遇到了一些问题。以下是我的代码：

public class Facility
{
    public string ID = "";
    public string Name = "";

    public List<Profile> Profiles { get; set; }
}

public class PrefSet
{
    public string SomeItem = "";
    public string AnotherItem = "";
}

public class Config
{
    public string Username = "";
    public string Password = "";

    public List<Facility> Facilities { get; set; }

    public static void SerializeObjectToFile<T>(T dataToSerialize, string filePath)
    {
        try
        {
            using (Stream stream = File.Open(filePath, FileMode.Create, FileAccess.ReadWrite))
            {
                XmlSerializer serializer = new XmlSerializer(typeof(T));
                XmlTextWriter writer = new XmlTextWriter(stream, Encoding.Default);
                writer.Formatting = Formatting.Indented;
                serializer.Serialize(writer, dataToSerialize);
                writer.Close();
            }
        }
        catch
        {
            File.Create(filePath);
        }
    }

    public static T DeserializeObjectFromFile<T>(string filePath)
    {
        try
        {
            XmlSerializer serializer = new XmlSerializer(typeof(T));
            T serializedData;

            using (Stream stream = File.Open(filePath, FileMode.Open, FileAccess.Read))
            {
                serializedData = (T)serializer.Deserialize(stream);
            }

            return serializedData;
        }
        catch
        {
            throw;
        }
    }
}

我想配置它，所以我将有一个像这样的XML输出：

<?xml version="1.0" encoding="Windows-1252"?>
<Config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Username>admin</Name>
  <Password>123456</VoiceServer>
  <Facilities>
    <Facility>
      <ID>1</ID>
      <Name>First Facility</Name>
      <Profiles>
        <Profile>
          <SomeItem>Value</SomeItem>
          <AnotherItem>Value</AnotherItem>
        </Profile>
        <Profile>
          <SomeItem>Value</SomeItem>
          <AnotherItem>Value</AnotherItem>
        </Profile>
        <Profile>
          <SomeItem>Value</SomeItem>
          <AnotherItem>Value</AnotherItem>
        </Profile>
      </Profiles>
    </Facility>
    <Facility>
      <ID>2</ID>
      <Name>Second Facility</Name>
      <Profiles>
        <Profile>
          <SomeItem>Value</SomeItem>
          <AnotherItem>Value</AnotherItem>
        </Profile>
        <Profile>
          <SomeItem>Value</SomeItem>
          <AnotherItem>Value</AnotherItem>
        </Profile>
        <Profile>
          <SomeItem>Value</SomeItem>
          <AnotherItem>Value</AnotherItem>
        </Profile>
      </Profiles>
    </Facility>
  </Facilities>
</Config>

请注意，可能有多个个人资料和工具列表。

以下是我用来执行序列化的代码：

Config config = new Config();
Facility fac = new Facility();
Profile prof = new Profile();

if (File.Exists(CONFIG_FILE)) config = Config.DeserializeObjectFromFile<Config>(CONFIG_FILE);

fac.ID = "1";
fac.Name = "Facility One";
prof.SomeItem = "Value";
prof.AnotherItem = "Value";

config.Facilities.Add(fac);
fac.Profiles.Add(prof);


Config.SerializeObjectToFile<Config>(config, CONFIG_FILE);

此外，例如，我希望能够编辑和保存对项目的更改。

我遇到的问题是它会以格式创建XML，但是如果我更改了一个值，它会创建一个全新的Facility项而不是更新现有的Facility列表项。

您的可序列化对象中的属性必须是公共的，具有

等属性

public string Username { get; set; }

然后你可以使用[xml]方面在你的类中构建你的xml结构

示例

[xmlignore]用于您不希望序列化的内容，例如方法和函数

[xmlnode("Username")]
public string Username { get; set; }

还有更多。你可以查看有关所有这些的xml序列化的microsoft文档。

您可能还必须将[serializable]方面放在班级之上。

序列化（和反序列化）XML列表
