在.NET 2.0你如何通过一个通用的委托参数的方法 [英] How do you pass a generic delegate argument to a method in .NET 2.0

问题描述

我有一类与委托声明如下...

I have a class with a delegate declaration as follows...

Public Class MyClass  
    Public Delegate Function Getter(Of TResult)() As TResult    

    ''#the following code works.
    Public Shared Sub MyMethod(ByVal g As Getter(Of Boolean))
        ''#do stuff
    End Sub
End Class

不过，我不想明确键入消气代表在方法调用。为什么如下我不能声明参数...

However, I do not want to explicitly type the Getter delegate in the Method call. Why can I not declare the parameter as follows...

... (ByVal g As Getter(Of TResult))

有没有办法做到这一点？

Is there a way to do it?

我的最终目标是能够设置一个委托财产getter和setter方法​​被调用的类。但我的读数表明，你不能这样做。所以我把setter和getter方法​​的类，然后我想调用类设置代理的参数，然后调用。是否有这样做的最佳实践。

My end goal was to be able to set a delegate for property setters and getters in the called class. But my reading indicates you can't do that. So I put setter and getter methods in that class and then I want the calling class to set the delegate argument and then invoke. Is there a best practice for doing this.

我意识到在上面的例子中，我可以设置设置为从调用类的委托变量...但我想创建紧密封装单身。

I realize in the above example that I can set set the delegate variable from the calling class...but I am trying to create a singleton with tight encapsulation.

有关的记录，我不能使用任何.net35宣布新的委托类型。

For the record, I can't use any of the new delegate types declared in .net35.

答案在C＃中是受欢迎的。

Answers in C# are welcome.

有什么想法？

推荐答案

您需要一个泛型类型参数添加到方法：

You need to add a generic type parameter to the method:

Public Shared Sub MyMethod(Of TResult) (ByVal g As Getter(Of TResult))

在C＃中，这将是

public static void MyMethod<TResult>(Getter<TResult> g) {
