Does anyone know how the Visual Studio 2005 object browser reads an assembly reference to list all the types and namespaces I tried using reflection but it bails at Assembly.GetTypes(). I guess I have some dependency assemblies not installed on my system so it throws the "One or more classes in a module could not be loaded. " error. However, when I add this assembly as my project reference, the object browser is able to read through this assembly. Is there some trick to do that
Assembly a = Assembly.ReflectionOnlyLoadFrom(filePath);
try
{
foreach (Type t in a.ManifestModule.GetTypes()){
string nsp = t.Namespace;
}
}
catch (Exception ex){
System.Diagnostics.
Trace.WriteLine(ex.Message);}

How about reading namespaces when dependency can not be resolved (missing on the local machine)
There is definitely a way because Lutz Roeder's Reflector can do that somehow, but i couldn't find any

When using ReflectionOnlyLoadFrom, you have to manually make sure that the Assembly's references have already been loaded or handle the AppDomain.ReflectionOnlyAssemblyResolve event and load them from there.
I wrote a quick sample that loads all the namespaces of the System assembly, and then displays them to the console window:
using System;
using System.Reflection;
using System.Collections.Generic;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
AppDomain.CurrentDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(OnAssemblyResolve);
Assembly assembly = Assembly.ReflectionOnlyLoad("System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");
Type[] types = assembly.GetTypes();
Dictionary<string, object> namespaces = new Dictionary<string, object>();
object holder = new object();
foreach (Type type in assembly.GetTypes())
{
if (type.Namespace != null)
{
namespaces[type.Namespace] = holder;
}
}
foreach (string key in namespaces.Keys)
{
Console.WriteLine(key);
}
}
static Assembly OnAssemblyResolve(object sender, ResolveEventArgs args)
{
return Assembly.ReflectionOnlyLoad(args.Name);
}
}
}
Hope that helps.
