WPF绑定到C＃struct变量 [英] WPF bind to a C# struct variable

问题描述

您好，我知道一个类可以替换结构但是对于其他函数我需要能够使用结构。



我需要在下面做些什么才能使结构生效？我想绑定到我的struct中的变量。



注意：在手机上键入，请忽略首字母和小错误。

Hello, I'm aware that a class would work to replace the struct but for other functions I need to be able to use a struct.

What do I need to change below to make this work for a struct? I want to bind to a variable inside my struct.

Note : Typed out on phone so please ignore capitilsation and minor errors.

Public struct MyStruct : INotifyPropertyChanged
{
      Public int _A;

      Public int A {
            Get { return _A; }
            Set { 
                  _A = value;
                  NotifyPropertyChanged("A");
             }
     }

     Public event propertychangedeventhandler PropertyChanged;

Private void NotifyPropertyChanged(String info)
{
    If(PropertyChanged != null){
         propertychanged(this, new PropertyChangedeventargs(info));
    }
}
};

Public class MyO{
     Public testStruct names = new testStruct();
}

Public partial class Mainwindow : window{
    MyO test = new MyO();
    
    Public MainWindow(){
          InitializeCommand();
          Textbox1.DataContext = test.names._A;
           Test.names2.A = 50;
    }
}

推荐答案

该类的代码可能如下所示：

The code of the class could look like that:

public class MyClass : INotifyPropertyChanged
{
  public int A {
    get { return myStruct._A; }
    set 
    { 
      myStruct._A = value;
      NotifyPropertyChanged("A");
    }

    public event PropertyChangedEventHandler PropertyChanged;
 
    private void NotifyPropertyChanged(string info)
    {
        if(PropertyChanged != null){
           PropertyChanged(this, new PropertyChangedEventArgs(info));
    }
  }

  private MyStruct myStruct = new MyStruct();
}

根据结构的目的，您可能会决定公开它的最佳方式。这里假设结构不会直接改变。

Depending of the purpose of the structure, you might decide the best way to expose it. Here it is assumed that the structure will not be changed directly.
