Handle optional parameters when I call a stored procedure

Question

Problem statement.

Basically I get 3 - 50 parameters that come back from a web service as a NVP array I then need to loop over them create the SQL command parameters for each and call the stored procedure. Is there a more efficient way to handle it than the approach below?

 using (SqlConnection connection = new SqlConnection(connectionString))
                         {
                             connection.Open();
                             using (SqlCommand cm = connection.CreateCommand())
                             {
                                 cm.CommandText = "MySproc";
                                 cm.CommandType = CommandType.StoredProcedure;
                                 foreach (var field in row)
                                 {

                                     cm.Parameters.AddWithValue("@" + field.Key.ToString(), field.Value.ToString());
                                 }
                                 cm.ExecuteNonQuery();
                             }
                         }

I personally use the ISNULL or COALESCE in the WHERE clause of the stored procedure. Unless your looking to do it inside your c#...
