首先使用propertychanged.fody与WPF数据绑定和EF 6.0数据库。 [英] Using propertychanged.fody with WPF databinding and EF 6.0 database first.

问题描述

有人可以告诉我如何让PropertyChanged.Fody首先使用WPF数据绑定和EF 6.0数据库吗？ 
我没有使用MVVM。 
我有一个名为Test的EF生成类如下.... 

  //   ------------------------------- -----------------------------------------------  
  //  <自动生成>  
  //  此代码是从模板生成的。 
  //    
  //  手动更改为此文件可能会导致应用程序出现意外行为。 
  //  此文件的手动更改将如果重新生成代码，则会被覆盖。 
  //  < / auto-generated>  
  //   ----------------------------------------- -------------------------------------  
 
 < span class =code-keyword> namespace  RMS_EF6 
 {
 使用系统; 
 使用 System.Collections.ObjectModel; 
 
  public   partial   class 测试
 {
  public   int  TestIdentityKey {获得;  set ; } 
  public  Nullable< int> TestNumber1 { get ;  set ; } 
  public  Nullable< int> TestNumber2 { get ;  set ; } 
  public   string  TestDescription1 { get ;  set ; } 
} 
} 

我创建了以下PropertyChanged.Fody类，如下所示.... / pre> 
 
 
 使用 PropertyChanged; 
 
 [AddINotifyPropertyChangedInterfaceAttribute] 
  public   partial   class 测试
 {
 私人  void  ArithmeticTest（）
 {
 TestNumber1 =  2  * TestNumber2; 
 Console.WriteLine（$   TestNumber1 = {TestNumber1} \ n + TestNumber2 = {TestNumber2}< /跨度>）; 
} 
} 
 
 
 
我可以通过WPF GUI手动输入来更新数据库中的各个字段使用WPF数据绑定。 
 
但是，当用户通过GUI输入数据时，我想在代码隐藏中执行类似ArithmeticTest（）的方法。例如，当TestNumber2的值因用户输入而改变时。 
任何人都可以告诉我需要添加到我的代码中才能实现这一目标吗？
 
 
 
 
 我是什么尝试过： 
 
 
 
我一直在试验上面的代码并且无处可去。

   TestNumber1 = {TestNumber1} \ n + TestNumber2 = {TestNumber2}）;

Can someone please advise me how I can get PropertyChanged.Fody to work with WPF databinding and EF 6.0 Database first?
I am not using MVVM.
I have an EF generated class called "Test" as follows....

//------------------------------------------------------------------------------
// <auto-generated>
//     This code was generated from a template.
//
//     Manual changes to this file may cause unexpected behavior in your application.
//     Manual changes to this file will be overwritten if the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------

namespace RMS_EF6
{
    using System;
    using System.Collections.ObjectModel;
    
    public partial class Test
    {
        public int TestIdentityKey { get; set; }
        public Nullable<int> TestNumber1 { get; set; }
        public Nullable<int> TestNumber2 { get; set; }
        public string TestDescription1 { get; set; }
    }
}

I have created the following PropertyChanged.Fody class as follows....

using PropertyChanged;

    [AddINotifyPropertyChangedInterfaceAttribute]
    public partial class Test
    {
        private void ArithmeticTest()
        {
            TestNumber1 = 2 * TestNumber2;
            Console.WriteLine($"TestNumber1 = {TestNumber1} \n + TestNumber2 = {TestNumber2}");
        }
    }

I can update the individual fields in the database with manual input through the WPF GUI OK using WPF databinding.

However, I want to execute methods like ArithmeticTest() in the code-behind when the users enter data through the GUI.  Eg when the value of TestNumber2 changes as a result of user input.
Can anyone please tell me what I need to add to my code to make this happen?

What I have tried:

I have been experimenting with the code above and have gotten nowhere.
