I want to know, if in the .net have a class to call a function/method in run time...

e.g:

Enter with a method name to call: sum(10,20)

The code sample, of my Ideia is something like this:

C#

class Program
{
    static void sum(int a, int b)
    {
        Console.WriteLine("{0}", a + b);
    }

    static void Main(string[] args)
    {
        Console.Write("Enter with a method name to call: ");
        string a = Convert.ToString(Console.ReadLine());

        // SAMPLE OF IDEA
        ProcessMacro PrM = new ProcessMacro(a);
    }
}

So, It's possible to do this ?
If yes, how I can do this ?

Thanks.

This was asked in the past hour. You use the CodeDom namespace to do this.

You can use reflection:

System.Reflection.MemberInfo[] members = this.GetType().GetMembers();
var parms = new object[0];
Type TypeToReflect = Type.GetType("System.Int32");
var EmitObj = System.Activator.CreateInstance(this.GetType(),false);
var x = this.GetType().InvokeMember("TestMethod2", BindingFlags.InvokeMethod, null, EmitObj, parms);

I am not an expert in Reflection, and there may be a way to execute on an existing object.
