Pass a method as an argument

Question

How do I pass a method as an argument? I do this all the time in Javascript and need to use anonymous methods to pass params. How do I do it in c#?

Answer 1

Your ParamMethod is of type Func because it takes one string argument and returns a string (note that the last item in the angled brackets is the return type).

So in this case, your code would become something like this:

protected void MyMethod(){
    RunMethod(ParamMethod, "World");
}

protected void RunMethod(Func ArgMethod, String s){
    MessageBox.Show(ArgMethod(s));
}

protected String ParamMethod(String sWho){
    return "Hello " + sWho;
}
