Question

I have a list of methods that I want to call named Method1, Method2, and so on. Is there a way I can just type in that number and then call the equivalent method? Delegates is one thing that comes to mind. Would this work?

Answer 1

You can use reflection:

MyClass myObj = ...;
var method = typeof(MyClass).GetMethod("Method"+num);
var res = method.Invoke(myObj, new object[] {arg1, arg2});

You could also use a dictionary of delegates:

var byNumber = new Dictionary<int,Func<MyClass,int>> {
    {1, (c) => c.Method1()}
,   {2, (c) => c.Method2()}
,   {3, (c) => c.Method3()}
};

var res = byNumber[1](myObj);
