多谢,我又修改一下,现在的能用不, mysql是5.5版本
public static int InsertReturnID(string InsertSQLString,   params MySqlParameter[] cmdParms)
        {
            using (MySqlConnection connection = new MySqlConnection(connectionString))
            {
                using (MySqlCommand cmd = new MySqlCommand())
                {
                    try
                    {
                        cmd.Connection = connection;
                        cmd.CommandType = CommandType.Text;
                        string InsertSQLString2 = "START TRANSACTION;" + InsertSQLString
                            + ";SELECT @last_insert_id := LAST_INSERT_ID();COMMIT;";
                        cmd.CommandText = InsertSQLString2;
                        if (cmdParms != null)
                        {
                            foreach (MySqlParameter parameter in cmdParms)
                            {
                                cmd.Parameters.Add(parameter);
                            }
                        }
                        int id = Convert.ToInt32(cmd.ExecuteScalar());
                        return id;
                      
                    }
                    catch (MySql.Data.MySqlClient.MySqlException e)
                    {
                        throw e;
                    }
                }
            }
        }

: 这绝对不是小概率。
: 用这个吧。
