Question

I want to create a delegate type in C# inside a method for the purpose of creating Anonymous methods.

For example:

public void MyMethod(){    delegate int Sum(int a, int b);     Sum mySumImplementation=delegate (int a, int b) {return a+b;}     Console.WriteLine(mySumImplementation(1,1).ToString()); } 

Unfortunately, I cannot do it using .NET 2.0 and C# 2.0.

Why do you want to create the delegate type within the method? What’s wrong with declaring it outside the method? Basically, you can’t do this – you can’t declare a type (any kind of type) within a method.

One alternative would be to declare all the Func/Action generic delegates which are present in .NET 3.5 – then you could just do:

public void MyMethod(){     Func<int, int, int> mySumImplementation =          delegate (int a, int b) { return a+b; };      Console.WriteLine(mySumImplementation(1,1).ToString()); } 

The declarations are on my C#/.NET Versions page.
