Activator.Creat eInstanceFrom problem

[CKR Rajesh]

Hi,

I have 2 dlls on which i have the same class MyClass defined. Say A.dll and
B.dll

The classes have a function (but different functionality)
void f();

I use .Net late binding using Activator.Creat eInstanceFrom method to
dynamically call the method f() in either dll.

But I see that once i successfully call the f() method of either of the dll,
I am not able to call the f() method in the other dll even if
I pass the other dll's name as the parameter to CreateInstanceF rom method.
Always f() from the dll which got executed first is always getting
executed...

Am i missing something?

Rather than passing the other DLL's name, try using Assembly.GetTyp e on
the appropriate loaded assembly, and then creating an instance using
Activator.Creat eInstance passing in the actual type.

Yes, that was what i did earlier... same results!

Note that types with exact same name exist on both the assemblies. But I
wonder why that creates a prob....

this is the code strip
Assembly m_oAssembly = Assembly.LoadFr om(assemblySour ce);
Type m_oTypeClass = m_oAssembly.Get Type(classname, false);

MethodInfo m_oMethodInfoRe questInitialize =
m_oTypeClass.Ge tMethod("Initia lize",System.Re flection.Bindin gFlags.Public
|System.Reflect ion.BindingFlag s.Instance);

object m_oClassInstanc e = Activator.Creat eInstance(m_oTy peClass);
m_oMethodInfoRe questInitialize .Invoke(m_oClas sInstance,m_oRe questArguments) ;

Thanks in advance

Could you post a short but complete example which we can use to
reproduce the problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean.
