c# - Creating a function dynamically at run-time

Question

It probably isn't even possible to do this, but I will ask anyway. Is it possible to create a function that receives a string and then uses it as a right side argument for the goes to operator (=>) used in lambda?

Actually, what I want to do is to be able to redefine an specific method of a specific class during runtime. I want to be write down a function with the program running and attaching it to a delegate. Is it possible?

You have several ways how to do it:

• dynamically create lambda expression (look at Dynamic LINQ: Part 1)
• dynamically create CodeDom model and compile it at run-time (look at CodeDom.Compiler namespace
• dynamically create C#/VB.NET source code and compile it at run-time (look at CSharpCodeProvider and VBCodeProvider classes )
• dynamically create object model, which can do same things like the method (look at Strategy Design Pattern
