try this:

SqlConnection conn = new SqlConnection();
SqlTransaction trans = conn.BeginTransaction();
try
{
   using (SqlCommand cmd = new SqlCommand("insert into Test (Id,Name) values(@iD, @Name)", conn, trans))
   {
      cmd.CommandType = CommandType.Text;
      cmd.AddParameter(SqlDbType.UniqueIdentifier, ParameterDirection.Input, "@iD", ID);
      cmd.AddParameter(SqlDbType.VarChar, ParameterDirection.Input, "@Name", Name);

      cmd.ExecuteNonQuery();
   }

   conn.CommitTransaction(trans);
}
catch (Exception ex)
{
   conn.RollbackTransaction(trans);
   throw ex;
