View 2 RepliesExtend Primitive Types Such As System.String And System.Int32?
Jul 25, 2010Is it possible to extend primitive types such as System.String and System.Int32 (IE: integer) in .Net 4 and if so how?
To be more specific, I am aware of the concept of partial classes but this doesnt seem to be the answer. Also I find that System.String is not inheritable and Int32 is a structure.
Lastly I am interested in knowing both a VB.Net and C# answer to the above question.
