Could not load file or assembly

[lasida]

Hi,

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.FileN otFoundExceptio n: 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\M icrosoft\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\M icrosoft\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?

[lasida]

sAssemblyName = "C:/Program Files/Myapplication/Myapplication.e xe";

// load the given assembly...
Assembly assem = Assembly.LoadFr om(sAssemblyNam e);
AssemblyName[] a = assem.GetRefere ncedAssemblies( );
foreach (AssemblyName assm in a)
{
Assembly ms = Assembly.LoadFr om(assm.Name);
Console.WriteLi ne("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.LoadFr om(assm.Name);" .. as you dont have the all *.dll in your bin dir.. of your application ...

[PRR]

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 ....

AppDomain myapp = AppDomain.CreateDomain("Test");//AppDomain.CreateDomain("Test", null, meset);
            //Assembly a1 = Assembly.Load("ClassLibrary1.dll");
           
                myapp.Load("ClassLibrary1");                 

            Assembly[] aa = myapp. GetAssemblies();

            foreach (Assembly a in aa)
            {
                Console.WriteLine(a.FullName);
                
                Type[] tt=a.GetTypes();
                foreach (Type t in tt)
                {
                    if (t.FullName.ToString() == "System.Object")
                    {
                        object o = Activator.CreateInstance(t);

                        if (o != null)
                        {
                            MethodInfo m = o.GetType().GetMethod("ToString");

                            Console.WriteLine(m.Invoke(o, null));
                        }
                    }

                    if (t.FullName.ToString() == "ClassLibrary1.Class1")// namespace+classname
                    {
                        object o = Activator.CreateInstance(t);

                        if (o != null)
                        {
                            MethodInfo m = o.GetType().GetMethod("my");// funtion: messagebox.show("Hi")

                            m.Invoke(o, null);
                        }
                    }
                }
            }
