Could not load file or assembly


I have developed an application in C#. Now I'm working on a tool which is again written in c# which will give me all the assemblies referenced by my application. In the code i need to get each assembly recursively and load it. When I run my tool some of the assemblies are loaded successfully but it end up giving following exception:

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms' o
r one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DW
ORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Can anyone help me out with this. Im totally stuck here.

Thanks in advance for all the inputs

could you post some sample code?
Nov 10 '08 #2
sAssemblyName = "C:/Program Files/Myapplication/Myapplication.exe";

// load the given assembly...
Assembly assem = Assembly.LoadFrom(sAssemblyName);
AssemblyName[] a = assem.GetReferencedAssemblies();
foreach (AssemblyName assm in a)
Assembly ms = Assembly.LoadFrom(assm.Name);
Console.WriteLine("name: " + ms.FullName);

This is the simple code i have written. Can you tell me what is going wrong?

i guess you cant do this "Assembly ms = Assembly.LoadFrom(assm.Name);".. as you dont have the all *.dll in your bin dir.. of your application ...

if you have *.dll in your bin of your application( which your application refers... not the .net Dll) and you want to put them into appdomain ...then i guess you could check the following code ....
Expand|Select|Wrap|Line Numbers
  2. AppDomain myapp = AppDomain.CreateDomain("Test");//AppDomain.CreateDomain("Test", null, meset);
  3.             //Assembly a1 = Assembly.Load("ClassLibrary1.dll");
  5.                 myapp.Load("ClassLibrary1");                 
  7.             Assembly[] aa = myapp. GetAssemblies();
  9.             foreach (Assembly a in aa)
  10.             {
  11.                 Console.WriteLine(a.FullName);
  13.                 Type[] tt=a.GetTypes();
  14.                 foreach (Type t in tt)
  15.                 {
  16.                     if (t.FullName.ToString() == "System.Object")
  17.                     {
  18.                         object o = Activator.CreateInstance(t);
  20.                         if (o != null)
  21.                         {
  22.                             MethodInfo m = o.GetType().GetMethod("ToString");
  24.                             Console.WriteLine(m.Invoke(o, null));
  25.                         }
  26.                     }
  28.                     if (t.FullName.ToString() == "ClassLibrary1.Class1")// namespace+classname
  29.                     {
  30.                         object o = Activator.CreateInstance(t);
  32.                         if (o != null)
  33.                         {
  34.                             MethodInfo m = o.GetType().GetMethod("my");// funtion: messagebox.show("Hi")
  36.                             m.Invoke(o, null);
  37.                         }
  38.                     }
  39.                 }
  40.             }
