ASP.NET配置文件保存由旧值覆盖

Question

我在网站上使用ASP.NET的配置文件功能.更新配置文件很奇怪!用户无法更新他/她自己的个人资料,无论是网站用户还是管理员,管理员都无法更新其他用户的个人资料.

在后端,调用Profile的save()后,SQL Server跟踪显示aspnet_Profile_SetProperties存储过程被调用两次.首先,使用旧值,使用旧值.第二次执行是在页面卸载后完成的.我的代码与事务无关.

为什么这么奇怪？

aspnet_regsql的安装是否存在问题,因为我已经安装了已卸载并再次安装它!？

web.config中

代码背后

private void UpdateProfile(ProfileCommon myprofile)
{
    myprofile.FirstName = tbFirstName.Text.Trim();
    myprofile.LastName = tbLastName.Text.Trim();
    myprofile.Email = tbEmail.Text.Trim();

    myprofile.Address.City = tbCity.Text.Trim();
    myprofile.Address.PostalCode = tbPostalCode.Text.Trim();
    myprofile.Contact.Phone = tbPhone1.Text.Trim();
    myprofile.Contact.Mobile = tbMobile.Text.Trim();
    myprofile.Save();
}
private ProfileCommon GetProfile()
    {
        ProfileCommon profile = this.Profile;
        if (Request.QueryString["UserName"] != null && HttpContext.Current.User.IsInRole("Admin"))
            profile = this.Profile.GetProfile(Request.QueryString["UserName"].ToString());
        else
            profile = this.Profile.GetProfile(HttpContext.Current.User.Identity.Name);
        return profile;
    }
protected void tbUpdateProfile_Click(object sender, ImageClickEventArgs e)
    {
        UpdateProfile(GetProfile());
    }

默认情况下,配置文件在ASP.NET页面执行结束时自动保存,请参阅配置文件元素(ASP.NET设置架构)文档.这解释了你观察到的第二个"神秘"豁免.

您可以尝试更改automaticSaveEnabled为false.
