Reintroducing my compiler class.

I created a class a couple of years ago which simplifies the CodeCom handling when you want to dynamically create objects in .NET. I got reminded of it when I read a question at stackoverflow.com.

The class can be used to easily generate .NET (C#) objects by having a class definition in a string variable.

First you have to define an interface (or base class) in your project:

public interface IWorld
{
    string Hello(string value);
}

Then you need to add a class to a string variable:

string code = @"namespace MyNamespace
{
  class Temp : IWorld
  {
      public string Hello(string value)
      {
          return ""World "" + value;
      }
  }
}";

And let’s generate an object and invoke the method:

Compiler compiler = new Compiler();

//repeat for all types (to automatically add namespaces and assemblies to the CodeDom compiler)
compiler.AddType(typeof(string));

// compile the code. Will throw an exception if it do not work.
compiler.Compile(code);

// create an instance
var obj = compiler.CreateInstance<IWorld>();

// and invoke it
string result = obj.Hello("World!");

Note that it was a long time ago that I wrote it. The example might not work 100%. (The Compiler class do work, the example might use it incorrectly).
