没有数据返回查看

Question

HomeController

[ValidateInput(false)]
public ActionResult Index()
{
    FormsAuthentication.SignOut();
    Session.Clear();
    Session.Abandon();
    EmployeeViewModel evm = new EmployeeViewModel();
    ViewBag.wresult = Request.Form["wresult"];
    if (!string.IsNullOrWhiteSpace(Request.Form["wresult"]))
    {
        XmlDocument wresult = new XmlDocument();
        wresult.LoadXml(Request.Form["wresult"]);
        XmlNodeList elemList = wresult.GetElementsByTagName("saml:Attribute");
        foreach (XmlNode node in elemList)
        {
            foreach (XmlAttribute attr in node.Attributes)
            {
                if (attr.Name.Equals("AttributeName") && attr.Value.Equals("emailaddress"))
                {
                    XmlNode child = node.FirstChild;
                    evm.EmployeeEmailId = child.InnerText;
                }
            }
        }
    }
    var emp = empModel.Get(evm.EmployeeEmailId);
    if (condition)
    {
        return RedirectToAction("Index", "XYZ", new { area = "PQR" });
    }
    return View("Test", evm)
}

The data that I am storing in the ViewBag here, as well as the object being returned with the view are returning blanks. I am unable to understand why this is.

evm object gets populated during the XML Processing, and there are some DB actions that happen to add more details to the object.

EmployeeViewModel evm = new EmployeeViewModel();

This is the first and last time you make use of evm before trying to return it. You're returning a new, blank instance of EmployeeViewModel() .
