Question

现在我的Create和Edit的POST操作有相当长的函数定义，因为有很多变量，我的bind属性包含所有变量。

public ActionResult Create([Bind(Include = "ProjectName,ProjectDescription,DateReceived,EffectiveDate,ExpirationDate,GeneralContractor,ProjectTerm,ProjectType,SubmissionNumber,PolicyNumber,Status,Underwriter,Division,BrokerCity,TAName,Branch,FirstNamedInsuredAddress,FirstNamedInsured,ProjectAddress")] Project project) {

和

public ActionResult Edit([Bind(Include = "ProjectID,ProjectName,ProjectDescription,DateReceived,EffectiveDate,ExpirationDate,GeneralContractor,ProjectTerm,ProjectType,SubmissionNumber,PolicyNumber,Status,Underwriter,Division,BrokerCity,TAName,Branch,FirstNamedInsuredAddress,FirstNamedInsured,ProjectAddress")] Project project) {

是否有替代方案可以缩短定义？

这是我的模特：

public class Project
{
    public Project()
    {
        FirstNamedInsuredAddress = new Address();
        ProjectAddress = new Address();
    }

    [Key]
    public int ProjectID { get; set; }

    [Required]
    [StringLength(150)]
    [Display(Name = "Project Name")]
    public string ProjectName { get; set; }

    [StringLength(1000)]
    [Display(Name = "Project Description")]
    public string ProjectDescription { get; set; }

    [Display(Name = "Date Received")]
    public string DateReceived { get; set; }

    [Display(Name = "Effective Date")]
    public string EffectiveDate { get; set; }

    [Display(Name = "Expiration Date")]
    public string ExpirationDate { get; set; }

    [StringLength(150)]
    [Display(Name = "General Contractor")]
    public string GeneralContractor { get; set; }

    [StringLength(25)]
    [Display(Name = "Project Term")]
    public string ProjectTerm { get; set; }

    [Display(Name = "Project Type")]
    public string ProjectType { get; set; }

    [Required]
    [Display(Name = "Submission Number")]
    public long SubmissionNumber { get; set; }

    [StringLength(20)]
    [Display(Name = "Policy Number")]
    public string PolicyNumber { get; set; }

    public string Status { get; set; }

    [StringLength(100)]
    public string Underwriter { get; set; }

    public string Division { get; set; }

    [StringLength(50)]
    [Display(Name = "Broker/City")]
    public string BrokerCity { get; set; }

    [StringLength(100)]
    [Display(Name="TA Name")]
    public string TAName { get; set; }

    public string Branch { get; set; }

    [Display(Name="First Named Insured Address")]
    public Address FirstNamedInsuredAddress { get; set; }

    [StringLength(150)]
    [Display(Name="First Named Insured")]
    public string FirstNamedInsured { get; set; }

    [Display(Name="Project Address")]
    public Address ProjectAddress { get; set; }

    public class Address
    {
        [StringLength(150)]
        [Display(Name="Line 1")]
        public string Line1 { get; set; }

        [StringLength(150)]
        [Display(Name="Line 2")]
        public string Line2 { get; set; }

        [StringLength(100)]
        public string City { get; set; }

        public string State { get; set; }

        [Display(Name="Zip Code")]
        public int? ZipCode { get; set; }

        [StringLength(100)]
        public string County { get; set; }

    }
}

作为Include的替代方法，您可以使用Exclude。它只会排除您不想发布的属性。可能在大多数情况下它会更少，或者如果你想要，你可以删除包含和排除，并且所有数据都将被发布。

例如：

[HttpPost]
[ActionName("Edit")]
public ActionResult Edit([Bind(Exclude = "GeneralContractor")] Project project)
{

}
