Execute a function from a variable in C#

Question

Is there any way so that you can call a function with a variable?

variable+"()";

or something like that, or would I have to use if statements?

A switch seems like it might be the answer, so if the variable's value=var1 I want it to execute var1(); if the value is var2 I want it to execute var2(); how would I code it?

Basically, I am trying to find a cleaner alternative to

if (variable == var1)
{
var1();
}
if (variable == var2)
{
var2();
}

Answer 1

It would be possible to use reflection to find a method in an object and call that method, but the simplest and fastest would be to simply use a switch:

switch (variable) {
  case "OneMethod": OneMethod(); break;
  case "OtherMethod": OtherMethod(); break;
}

You could use Reflection http://msdn.microsoft.com/en-us/library/ms173183(v=vs.80).aspx to access any function or member by name. It takes some getting used to though. It also has performance issues, so if you can avoid using it, you should.
