I and one of friend are working in a same project in ASP.Net, But the problem is he is expert in VB and I am fluent in C#.

Now the question is can we both work together using both the language C# and VB OR both have work in same language. I mean code of C# can be converted in VB or code of VB can be converted in C#? If it is possible then please tell me how can we do this?
