Google? MSDN?

It's interesting which answers are you expecting? With this way of asking you'd better ask soothsayer from the "Matrix"

It's not just "using", it's 1) having some assembly referenced, 2) looking at the name space(s) used by the type declarations of the assembly you reference, 3) adding appropriate "using" clauses to your code.

With Visual Studio, you can open you project's References node in Solution Explorer, add the reference if you did not do it yet and then click on the tree node of the referenced assembly. In the document view you can browse the assembly in question and find out all the name spaces.

Also, an assembly can be loaded during run-time using methods of the class System.Reflection.Assembly.

If this is not a .NET assembly, P/Invoke should be used.

If it is not a .NET componant, have you made sure the dll that contains this is in your References? You may need to add it there.

Which Data Access are you using. you need to add the name space at the top of your code, something like this. I don't know your code so don't take this literally.

C#

using System.Data;

To get an exact namespace to use, show you your code or figure it out from MSDN. If it is third party tool, you need to figure out which namespace to include.
