调试易

public int aaa(string aname, int atype)
    {
        try
        {
            conn.Open();
            //string SqlStr = null;
            SqlCommand Cmd = conn.CreateCommand();
            Cmd.CommandType = CommandType.StoredProcedure;
            Cmd.CommandText = "query_xx";
            Cmd.Parameters.Add("@aname", SqlDbType.VarChar, 50);
            Cmd.Parameters.Add("@atype", SqlDbType.Int, 4);            Cmd.Parameters.Add("@aid", SqlDbType.Int, 4);
            Cmd.Parameters["@aid"].Direction = ParameterDirection.Output;            Cmd.Parameters["@aname"].Value = aname;
            Cmd.Parameters["@aname"].Value = atype;
            Cmd.ExecuteNonQuery();
            int result = Convert.ToInt32(Cmd.Parameters["@aid"].Value);
            return result;
        }
        catch
        {
            return 0;
        }
    }
执行到Cmd.ExecuteNonQuery();就没执行了,就是说Cmd.ExecuteNonQuery();还没有执行,上面哪写错了?? 呵呵
