Question

我使用ChangePassword ASP.NET Control创建了一个空页面。此页面没有任何代码隐藏。但是当我使用此控件时，它会显示此错误。

此版本的SQL不支持用户实例登录标志服务器。连接将被关闭。

这是我的ASPX页面

        </tr>
    </table>
</ChangePasswordTemplate>

而且，这是背后的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;


namespace IgnisAccess
{
    public partial class UserProfile : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void ChangePassword1_ChangedPassword(object sender, EventArgs e)
        {


        }

        protected void ChangePassword1_ChangingPassword(object sender, LoginCancelEventArgs e)
        {

        }

        protected void ChangePassword1_ContinueButtonClick(object sender, EventArgs e)
        {

        }
    }
}

您需要检查数据库连接字符串 - 看起来您正在某处使用UserInstance=true。

SQL Server Express 上仅支持 这个标志 - 所以如果您使用的是任何其他版本的SQL Server，则需要更改

ChangePassword Control中此版本的SQL Server错误不支持用户实例登录标志
