View source for .Net Code Sample - Reflecting assembly with missing dependency

The code below aims to answer the question: Are you able to Reflect an assembly with missing dependencies?

I.e. an assembly that you cannot execute and if given the source code, cannot compile

== AssemblyA.dll ==

 using System;
 using System.Collections.Generic;
 using System.Text;
 namespace Owasp.Net.test
 {
   public class AssemblyA
   { 
 }

== AssemblyB.dll ==

 using System;
 using System.Collections.Generic;
 using System.Text;
 using Owasp.Net.test; 
 namespace Owasp.Net.test
 {
   class Program
   {
     static void Main(string[] args)
     {
       Console.WriteLine(Owasp.Net.test.AssemblyA.AssemblyAMethod());
     }
   }
 }



== FileReflector.exe ==

 using System;
 using System.Collections.Generic;
 using System.Text;
 using System.Reflection;
 using System.IO;
 namespace FileReflector
 {
  class Program
  {
    static void Main(string[] args)
    {
      if (args.Length == 0)
        Console.WriteLine("You must enter a file to analyse");
      else
      {
        string strPathToFileToAnalyse = Path.Combine(Environment.CurrentDirectory, args[0].ToString());        
        Assembly aAssemblyToAnalyze = Assembly.ReflectionOnlyLoadFrom(strPathToFileToAnalyse);
        foreach (Module mModule in aAssemblyToAnalyze.GetModules())
        {
          Console.WriteLine("\n Module: {0}", mModule.Name);
          foreach (Type tType in mModule.GetTypes())
          {
            Console.WriteLine("\t Class: {0}", tType.Name);
            foreach (MethodInfo mMethod in tType.GetMethods())
            {
              Console.WriteLine("\t\t Method: {0}", mMethod.Name);
            }
          }
        }
      }                       
    }
  }

== Executing AssemblyB.exe with AssemblyA.dll in the same Directory: ==


 This is a String from Assembly A


== Executing AssemblyB.exe with AssemblyA.dll DELETED From same Directory: ==
