Reflection - Access custom attributes by name

Question

I'm attempting to see if a given method is decorated with an attribute, (the attribute in question is NUnit.Framework.TestAttribute) but I need to be able to check for the attribute regardless of what version the attribute is. Currently, I have nunit.framework.dll version 2.6.2 in the project using reflection, and version 2.6.0 of the dll in the test. The reflection is not finding the attribute.

Is there some way to do

bool isTest = method.GetCustomAttributes(typeof(TestAttribute), true).Length > 0;

without having access to the correct version of the TestAttribute dll?

where method is of type MethodInfo.

You can get all attributes and filter by name:

method.GetCustomAttributes(true)
      .Where(a => a.GetType().FullName == "NUnit.Framework.TestAttribute");
