Type.GetType("namespace.a.b.ClassName") returns null

This code:

Type.GetType("namespace.a.b.ClassName")

returns null.

and I have in the usings:

using namespace.a.b;

Update:

The type exists, it's in a different class library, and i need to get it by string name.

Solution 1:

Type.GetType("namespace.qualified.TypeName") only works when the type is found in either mscorlib.dll or the currently executing assembly.

If neither of those things are true, you'll need an assembly-qualified name:

Type.GetType("namespace.qualified.TypeName, Assembly.Name")

Solution 2:

You can also get the type without assembly qualified name but with the dll name also, for example:

Type myClassType = Type.GetType("TypeName,DllName");

I had the same situation and it worked for me. I needed an object of type "DataModel.QueueObject" and had a reference to "DataModel" so I got the type as follows:

Type type = Type.GetType("DataModel.QueueObject,DataModel");

The second string after the comma is the reference name (dll name).
