如何创建一个视图模型和地图的EDMX设计器类

问题描述

可以为任何人的EDMX设计器类创建一个视图模型提供了一个链接

can anybody provide a link for creating a viewmodel for the edmx designer class

想我的EDMX文件名为School.edmx，它有school.Designer.cs类。
在设计类，我有如下因素的实体对象

suppose my edmx file is named School.edmx and it has school.Designer.cs class. In the designer class i have the folowing entity object

[EdmEntityTypeAttribute(NamespaceName="teamworkModel", Name="User")]
[Serializable()]
[DataContractAttribute(IsReference=true)]
public partial class User : EntityObject
{

    #region Primitive Properties

    [EdmScalarPropertyAttribute(EntityKeyProperty=true, IsNullable=false)]
    [DataMemberAttribute()]
    public global::System.Int32 User_Pk
    {
        get
        {
            return _User_Pk;
        }
        set
        {
            if (_User_Pk != value)
            {
                OnUser_PkChanging(value);
                ReportPropertyChanging("User_Pk");
                _User_Pk = StructuralObject.SetValidValue(value);
                ReportPropertyChanged("User_Pk");
                OnUser_PkChanged();
            }
        }
    }
    private global::System.Int32 _User_Pk;
    partial void OnUser_PkChanging(global::System.Int32 value);
    partial void OnUser_PkChanged();


    [EdmScalarPropertyAttribute(EntityKeyProperty=false, IsNullable=false)]
    [DataMemberAttribute()]

    [StringLength(20,ErrorMessage="Name cannot exceed 20 characters")]
    [RegularExpression(@"^([a-zA-Z0-9 \.\&\'\-]+)$", ErrorMessage = "Invalid name")]
    public global::System.String User_Name
    {
        get
        {
            return _User_Name;
        }
        set
        {
            OnUser_NameChanging(value);
            ReportPropertyChanging("User_Name");

    partial void OnUser_NameChanged();


    [EdmScalarPropertyAttribute(EntityKeyProperty=false, IsNullable=false)]
    [DataMemberAttribute()]
    [Email(ErrorMessage="Invalid email address")]
    [Required(ErrorMessage="Please enter email address")]
    public global::System.String User_Mail_Id
    {
        get
        {
            return _User_Mail_Id;
        }
        set
        {
            OnUser_Mail_IdChanging(value);
            ReportPropertyChanging("User_Mail_Id");

    public global::System.DateTime User_Creation_Date
    {
        get
        {
            return _User_Creation_Date;
        }

    }
    private global::System.DateTime _User_Creation_Date;
    partial void OnUser_Creation_DateChanging(global::System.DateTime value);
    partial void OnUser_Creation_DateChanged();

我在上面的实体对象以下各列（User表）User_PK，User_Name的，USER_PASSWORD，USER_EMAIL_ID .....

I have the following columns in the above entity object (User table)User_PK,User_Name,User_Password,User_Email_ID.....

请任何人都可以提出如何创建上述实体对象的视图模型包含除USER_PASSWORD和USER_EMAIL_ID上述所有列，因为我需要用它作为强类型的ViewModel我view.I还需要使用另一个表中同样的视图模型与选定的列....

Please can anyone suggest how to create a viewmodel for the above entity object that contains all the above columns except User_Password and User_Email_ID because i need to use it as strongly typed viewmodel for my view.I also need to use another table in the same viewmodel with selected columns....

推荐答案

编辑：修改回答关于其他实体额外的属性注释

Modified to answer comment about extra properties from other Entities

这可能有助于

public class UserViewModel
{
public int Pk{get;private set;}
public string Name{get;set;}
public DateTime CreationDate{get;set;}
public string ProjectName{get;set;}
public DateTime ProjectCreated{get;set;}
}

该视图模型是你的实体平铺版本。

The ViewModel is a flattened version of you entities.
