Question

I have the body of a method stored as a string and I’m looking to create this method dynamically. However, I’m unsure how to assign its body. I’ve come across a rather complex method using CodeDom, and another using Emit with OpCodes. Is there a simpler way to utilize the existing code from a string variable?

string method_body = "return \"Hello, world!\";"; // there is a method body
DynamicMethod dm = new System.Reflection.Emit.DynamicMethod("My_method",
                 typeof(string), new Type[] { }); // some way to create method dynamically
// any way to set body?
string result = (string)dm.Invoke(...); // I need to write result in a variable

You need to take a look at these namespaces:

System.Reflection;
System.CodeDom.Compiler;
Microsoft.CSharp;
