我有一个asp.net网络表单网站，在PC上运行良好。但是，当我尝试从移动设备访问它时，它会给出一个对象引用错误。该站点是asp.net 4.5.1并使用普通的asp.net服务器控件。
public partial class index : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
LoginView lView = (LoginView)this.Master.FindControl("LoginView1");
lView.Visible = false;
if (Request.QueryString["exp"] != null)
{
string msg = "Session expired please login.";
ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(), "$(function() { LoginFail('" + msg + "'); });", true);
}
}
protected void btnLogin_Click(object sender, EventArgs e)
{
ManchesterContext context = new ManchesterContext();
if (Membership.ValidateUser(txtUserId.Text, txtPassword.Text))
{
MembershipUser user = Membership.GetUser(txtUserId.Text);
aspnet_Users dbUser = context.aspnet_Users.Where(u => u.UserName.Equals(user.UserName)).FirstOrDefault();
if (dbUser.PassUpdated)//This means user has already changed default password. Perform login.
{
SetAuthenticationCookie(user);
aspnet_Users dbEntry = context.aspnet_Users.Where(u => u.UserName == user.UserName).FirstOrDefault();
SessionInfo.InitSession(dbEntry.UserId, dbEntry.UserName);
Session.Add("USR_KEY", dbEntry.UserId);
FormsAuthentication.RedirectFromLoginPage(user.UserName,false);
}
else //User has not updated default password.
{
Session.Add("TEMP_USR", txtUserId.Text);
Session.Add("TEMP_PASS", txtPassword.Text);
Response.Redirect("ChangePassword.aspx");
}
}
else
{
string msg = "Invalid User Id or Password.";
ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(), "$(function() { LoginFail('" + msg + "'); });", true);
}
}
public void SetAuthenticationCookie(MembershipUser user)
{
Response.Cookies.Clear();
var cookie = new HttpCookie(FormsAuthentication.FormsCookieName)
{
Expires = System.DateTime.Now.AddDays(-1),
HttpOnly = true
};
HttpContext.Current.Response.Cookies.Add(cookie);
return;
}
}
