get assembly by class name

Question

Is there any way to get the assembly that contains a class with name TestClass? I just know the class name, so I can\'t create an instance of that. And

Answer 1

Actually knowledge of classname is enough in most scenarios. MSDN says - If the type is in the currently executing assembly or in Mscorlib.dll, it is sufficient to supply the type name qualified by its namespace.

Type neededType = Type.GetType("TestClass"); //or typeof(TestClass) 
Assembly a = neededType.Assembly;

In case you dont know the assembly containing type (though i cant imagine why) -

Assembly[] assemblies = AppDomain.CurrentDomain.GetAssemblies();
Asssembly result = assemblies.FirstOrDefault(a=>a.GetType("TestClass",false)!=null);

The only restriction - assembly containing TestClass should have been already loaded at the moment of calling such code.

Hope this'll help. :)
