calling a function using string in runtime

Question

I am trying to find a way to call a function by typing its name in a text box and clicking a button , i have 417 functions and they don't take any variables

for example i want to type in a textbox

listproducts

and click a button

then listproducts() will get called.

is it possible to do such things without using select case or if statements? or is it possible to assign a string name to a function and call it by that name?

I have edited your title. Please see, "Should questions include “tags” in their titles?", where the consensus is "no, they should not". — John Saunders

You need to use reflection. Assuming the the functions you want to call are all static methods on a class called Foo you can do something like this.

Dim functionName as String = "listproducts"
Dim fooType As System.Type = GetType(Foo)
Dim Method As System.MethodInfo = fooType.GetMethod(functionName)
Method.Invoke(Nothing, Nothing)
