How do I read an attribute on a class at runtime?

I am trying to create a generic method that will read an attribute on a class and return that value at runtime. How do would I do this?

Note: DomainName attribute is of class DomainNameAttribute.

[DomainName("MyTable")]
Public class MyClass : DomainBase
{}

What I am trying to generate:

//This should return "MyTable"
String DomainNameValue = GetDomainName<MyClass>();
