1. compile following program using gmcs
using System;
using System.Reflection;
using System.Reflection.Emit;
public class C
{
static void Emit (Type t)
{
/// INITIAL ASSEMBLY CREATION
AssemblyName name = new AssemblyName();
name.Name = "o";
AssemblyBuilder builder =
AppDomain.CurrentDomain.DefineDynamicAssembly(name,
AssemblyBuilderAccess.Save);
ModuleBuilder mb = builder.DefineDynamicModule("out", "bla.dll");
///////////
TypeBuilder ta = mb.DefineType("MyEnum", TypeAttributes.Sealed, t,
null);
Type quxc = ta.CreateType();
ta.CreateType ();
builder.Save("bla.dll");
}
public static void Main (string[] args)
{
Assembly a = Assembly.LoadFile (args[0]);
Console.WriteLine (a.FullName);
Type t = a.GetType ("System.Enum");
Print (t);
Emit (t);
}
static void Print (Type t)
{
Console.WriteLine (t.FullName);
Console.WriteLine (t.Assembly.FullName);
}
}
2. Run it using enclosed test libraries
Test 1: test.exe lib1.dll
Expected Output: No error and correctly emitted bla.dll
Actual Output:
lib1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
