Following code sample loads assembly from GAC (global assembly cache) on button click:
protected void btn_Click(object sender, EventArgs e)
{
AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5");
Assembly al = Assembly.Load(asm);
Type t = al.GetType("ClassLibrary1.Class1");
MethodInfo m = t.GetMethod("Method1");
str = "reflection - " + (string)m.Invoke(null, null);
MessageBox.Show(str);
}

Hi,
There are basically two methods in .Net to generate dynamic code through your program. One is to use CodeDom library while other is to use Reflection Emit library. The System.CodeDom library is used to generate the standard CLS (Common Language Specification) compliant code that can be emitted in any of .Net languages. On the other hand, the System.Reflection.Emit library is used to generate the MSIL (Micrsoft Intermediate Language) code. Dot Net Reflection Emit allows us to construct assemblies, modules, types at runtime and define code inside these types.

Assembly.loadFrom("filepath")
An example looks as follows:
using System;
namespace Demo.Interfaces
{
/// <summary>
/// Summary description for Class1.
/// </summary>
public interface IPlugin
{
int Calculate(int input);
}
}
Create this class in a separate class library (so that it becomes a separate assembly file). In this example, I'm just using an interface with one method in order to calculate a left-associative calculation on integer values. Basically, what I want to do is something like this:
(((((input operation1) operation2) operation3) operation4) operation5)
Where every operation is execute by a class implementing the IPlugin interface. An example of some implementations is this:
using System;
using Demo.Interfaces;
namespace Demo.Test
{
/// <summary>
/// Summary description for Class1.
/// </summary>
public class Test1 : IPlugin
{
public int Calculate(int input)
{
return input * 2;
}
}
public class Test2 : IPlugin
{
public int Calculate(int input)
{
return input + 3;
}
}
}
