Hi, assuming your using Visual Studio .NET and the class is compiled into a DLL then you have to reference the DLL file by going to Project --> Add Reference --> Browse. You then have to refer to the class in your code by specifying its full namespace, e.g.:

ClassNameSpace.ClassName object = new ClassNameSpace.ClassName();

or you could add a using directive at the top of the file to include the namespace, then you can simply refer to the class using its name.

If its just a .cs file then you can add that file into your project by going into Project --> Add Existing Item and again, use the same method above to refer to it in your code.

Sorry, don't call your object reference "object" like I did in my example, its a class in the framework!

It is a cs file, and I have added it to the project from the solution, but I'm not sure what to do next, can you give me some code example.

once you have declared the instance you can use the methods with dot notation so.....

ClassName obj = new ClassName();

obj.MethodName(Arg1, Arg2);

for methods returning values....

string str = obj.MethodName(Arg1, Arg2);

hope this helps.
