Can someone explain to me the purpose of this:<br />

When do you use the ParameterDirection.Output.<wbr />.. or ParameterDirection.Input? When would you use these. I've read something in msdn but I still do not see the point...

Can someone explain to me the purpose of this:

    SqlParameter myParameter = new SqlParameter("@Description", SqlDbType.VarChar);
    myParameter.Direction = ParameterDirection.Output;
 }

When do you use the ParameterDirection.Output... or ParameterDirection.Input? When would you use these. I've read something in msdn but I still do not see the point...

ParameterDirection

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
