    MARS is a feature that allows the execution of multiple batches on a single connection. It is a new feature supported in sqlserver 2005.
    MARS is disabled by default on the Connection object. You have to enable it with the addition of MultipleActiveResultSets=true in your connection string.
    SqlConnection conn = new SqlConnection ( @"Data Source=ServerName;
    Initial Catalog=DataBaseName;Integrated Security=SSPI; MultipleActiveResultSets=true;");
