What's that

Syntactic sugar improvements for the RunSharp library. RunSharp is a nice user-friendly wrapper for Reflection.Emit API developed by Stefan Simek and Matthew Wilson.

Original RunSharp code:

MyTypeGen.Public.Static.Method(typeof(void), "Main")
   .Parameter(typeof(string[]), "args")
   .Attribute(typeof(DescriptionAttribute), "Entry Point");

My version:

MyTypeGen.Public.Static.Void("Main")
   .Parameter<string[]>("args")
   .Attribute<DescriptionAttribute>("Entry Point");

Overview

RunSharp is a layer above the standard .NET Reflection.Emit API, allowing to generate/compile dynamic code at runtime very quickly and efficiently (unlike using CodeDOM and invoking the C# compiler). To the best of my knowledge, there is no such library available at the moment.

Example

A simple hello world example in C#

public class Test
{
   public static void Main(string[] args)
   {
      Console.WriteLine("Hello " + args[0]);
   }
}

can be dynamically generated using RunSharp as follows:

AssemblyGen ag = new AssemblyGen("hello.exe");
TypeGen Test = ag.Public.Class("Test");
{
   CodeGen g = Test.Public.Static.Method(typeof(void), "Main", typeof(string[]));
   {
      Operand args = g.Param(0, "args");
      g.Invoke(typeof(Console), "WriteLine", "Hello " + args[0] + "!");
   }
}
ag.Save();

The above code should generate roughly the same assembly as if the first example was compiled using csc.
