Question

所以我已经建立了登录系统，现在我不想让用户更新他们的信息。我认为这段代码可以正常工作，但事实并非如此：

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

    MembershipUser usr = Membership.GetUser();
    if (usr.IsApproved == false)
    {
        Response.Redirect("~/Login.aspx");
    }
    var p = Profile.GetProfile(usr.UserName);
    /* Displays all current profile information once the page loads */
    FirstName.Text = p.fName;
    LastName.Text = p.lName;
    Address.Text = p.Address;
    Email.Text = usr.Email;
    Company.Text = p.Company;
}
/* Simple button to take you to the home screen */
protected void Button2_Click(object sender, EventArgs e)
{
    Response.Redirect("~/default.aspx");
}

protected void UpdateButton_Click(object sender, EventArgs e)
{
    MembershipUser usr = Membership.GetUser();
    var p = Profile.GetProfile(usr.UserName);
    /* Update all information that the user has changed */
    p.fName = FirstName.Text;
    p.Save();
    p.lName = LastName.Text;
    p.Save();
    p.Address = Address.Text;
    p.Save();
    usr.Email = Email.Text;
    Membership.UpdateUser(usr);
    p.Company = Company.Text;
    p.Save();
    Success.Text = "User Information has been updated";
    /* Redisplaying the updated user information */
    FirstName.Text = p.fName;
    LastName.Text = p.lName;
    Address.Text = p.Address;
    Email.Text = usr.Email;
    Company.Text = p.Company;
  }
}

问题似乎是，无论我在文本框中更改文本，都不会改变原来在文本框中的内容。因此，如果最初用户名字是Bob，我在点击更新按钮时将其更改为Robert，则不会将其更改为Robert。这似乎是一个简单的修复，但我有点迷失。总结一下，主要问题是如何将用户信息更新为用户在文本框中输入的新文本。

将!Ispostback放在页面加载

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
    MembershipUser usr = Membership.GetUser();
    if (usr.IsApproved == false)
    {
        Response.Redirect("~/Login.aspx");
    }
    var p = Profile.GetProfile(usr.UserName);
    /* Displays all current profile information once the page loads */
    FirstName.Text = p.fName;
    LastName.Text = p.lName;
    Address.Text = p.Address;
      Email.Text = usr.Email;
      Company.Text = p.Company;
   }
}

如果您不使用它，当信息进入服务器时，您将获得旧值。
