C#做的登陆界面在检查输入的密码时就算输入正确也报出错

Question

小弟初学C#,做了一个登陆界面，输入了正确的密码但还是出错，下面是我的程序请高手帮忙看看，谢谢！string strConn = "Data source=LEE-03C9CC53F71\\SQLEXPRESS;Initial Catalog=Lee;User ID=sa;Password=lee";
            DbProviderFactory dbProviderFactory = DbProviderFactories.GetFactory("System.Data.SqlClient");
            DbConnection dbConn = dbProviderFactory.CreateConnection();
            dbConn.ConnectionString = strConn;
            dbConn.Open();
            DbCommand dbComm = dbProviderFactory.CreateCommand();
            dbComm.Connection = dbConn;
            dbComm.CommandText = "select Id,Password from SystemAdministrator where Id='" + id + "'";//这里的id是从外面传入的
            IDataReader reader = dbComm.ExecuteReader();
            try
            {
                if (reader.Read())
                {
                    if (reader.GetString(1) == strps)//就是这里，就算输入了正确的密码也通不过，我是从外面传入的一个字符串strps
                    {
                        SysAdministrator sa = new SysAdministrator();
                        sa.Show();
                    }
                    else
                    {
                        MessageBox.Show("密码错误");
                    }
                }
                else
                {
                    MessageBox.Show("账号错误");
                }
            }
            finally
            {
                reader.Close();
                dbConn.Close();
                dbConn.Dispose();
            }

自己搞定了，原来是空格在作怪。
