How to get Namespace of an Assembly?


Consider i have an assembly(class library dll) which i have loaded using the following code,

Assembly a = Assembly.LoadFrom(@"C:\Documents and Settings\E454935\My Documents\Visual Studio 2005\Projects\nunit_dll_hutt\for_hutt_proj\bin\Debug\asdf.dll");   

and i need to get the type of the Assembly. In order to get the type i need the namespace of the assembly.

Type t = asm.GetType("NAMESPACE.CLASSNAME",false,true);             

how can i get the Namespace in the above line.?! as inorder to get the Namespace, i need to get the type..?


i.e i need to get the Namespace of the assembly which can be used to get its Type.

Thanks in advance

Use Assembly.GetTypes() - this will get you a collection of all types and then you can get the Namespace property for each of them.

Then I guess you can simply check that all the types have same Namespace value and use this value. Otherwise add some other logic to detect what namespace to consider primary.

An assembly can contain multiple namespaces. I think what you really want to ask is how to get a type from an assembly without specifying the namespace.

I don't know if there is a better way, but you can try looking for the specific type like this (add - using linq;):

myassembly.GetTypes().SingleOrDefault(t => t.Name == "ClassName")

This will effectively throw if there is more than 1 class with that name under different namespaces (because the Single method ensures there is only 1).

For a list of the namespaces for that class you can:

Assembly.Load("ClassName").GetTypes().Select(t => t.Namespace).Distinct();
