將班級成員設置爲功能

Question

我有一個班級只能通過反思與另一班級互動。我正在與之交流的這個班有一些代表，我正在設置他們。下面有他們的樣子：

public class ClassThatIAmReflecting { 
    public delegate void OnSuccessDelegate(bool value); 

    public static OnSuccessDelegate OnSuccess; 

    public void OnClassThatIAmReflectingSuccess(bool arg) { 
     if(OnSuccess != null) 
      OnSuccess(arg); 
    } 
} 

這裏就是我想：

public class MyClass { 

    void Init() { 
     Type type = Type.GetType("ClassThatIAmReflecting"); 

     FieldInfo fieldInfo = type.GetField("OnSuccess", BindingFlags.Public | BindingFlags.Static); 
     fieldInfo.SetValue(null, HandleOnSuccess); 
    } 

    void HandleOnSuccess(bool value) { 
     // do stuff ... 
    } 
} 

我得到的錯誤是，它無法將動作轉換爲對象。任何幫助我如何做到這一點？

Answer 1

你的類應該是：

public class MyClass 
{ 

    public void Init() 
    { 
     Type type = typeof(ClassThatIAmReflecting); 
     FieldInfo fieldInfo = type.GetField("OnSuccess", BindingFlags.Public | BindingFlags.Static); 
     var fieldType = fieldInfo.FieldType; 

     var methodInfo = this.GetType().GetMethod("HandleOnSuccess", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance); 
     var del = Delegate.CreateDelegate(fieldType, this, methodInfo); 

     fieldInfo.SetValue(null, del); 

     //test 
     ClassThatIAmReflecting.OnSuccess(true); 
    } 

    private void HandleOnSuccess(bool value) 
    { 
     Console.WriteLine("Called"); 
    } 
}
