c# - Linq to SQL - 在 Html.TextBoxFor 中格式化 DateTime

Question

我有一个名为 DExamination.dbml 的 .dbml Linq to SQL 类

[global::System.Data.Linq.Mapping.TableAttribute(Name="dbo.Examination")]
public partial class Examination : INotifyPropertyChanging, INotifyPropertyChanged
{

    private static PropertyChangingEventArgs emptyChangingEventArgs = new PropertyChangingEventArgs(String.Empty);

    private int _Id;

    private string _Title;

    private System.Nullable<System.DateTime> _StartDate;
}
...
    [global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_StartDate", DbType="DateTime")]
    public System.Nullable<System.DateTime> StartDate
    {
        get
        {
            return this._StartDate;
        }
        set
        {
            if ((this._StartDate != value))
            {
                this.OnStartDateChanging(value);
                this.SendPropertyChanging();
                this._StartDate = value;
                this.SendPropertyChanged("StartDate");
                this.OnStartDateChanged();
            }
        }
    }
...

在编辑中显示

<%: Html.TextBoxFor(model => model.Examination.StartDate)%>

如何将 StartDate 格式化为 "dd/MM/yyyy"

我试过在上面添加 DisplayFormat ...

[global::System.ComponentModel.DataAnnotations.DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_StartDate", DbType="DateTime")]
    public System.Nullable<System.DateTime> StartDate
    {
        get
        {
            return this._StartDate;
        }
        set
        {
            if ((this._StartDate != value))
            {
                this.OnStartDateChanging(value);
                this.SendPropertyChanging();
                this._StartDate = value;
                this.SendPropertyChanged("StartDate");
                this.OnStartDateChanged();
            }
        }
    }

但不工作

谁有解决办法？

您需要装饰您的模型:

[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public DateTime StartDate{ get; set; }

并且该属性已经存在于您的代码中，只是顺序错误。
