从会话对象获取值

Question

这些是我设置会话对象的代码。我想使用该对象来获取登录用户的信息。但我无法这样做，我得到错误'输入字符串不正确的格式'。我需要帮助这里了解如何从我的会话对象

public UserLoginDetails LoggedUserDetails 
    { 
     set { Session["loggeduserdetails"] = value; } 
     get 
     { 
      if (Session["loggeduserdetails"] == null) 
      { 
       if (Session["username"] == null) 
       { 
        Response.Redirect("../Authentication/Login.aspx"); 
       } 

       if (Session["password"] == null) 
       { 
        Response.Redirect("../Authentication/Login.aspx"); 
       } 

       DAL.LoginHistoryDAL LoginDAL = new DAL.LoginHistoryDAL(); 

       DataSet Ds = LoginDAL.AuthenticateUser(Session["username"].ToString(), EncryptionUtility.Encrypt(Session["password"].ToString())); 

       UserLoginDetails ULD = new UserLoginDetails(); 

       if (Ds.Tables[0].Rows.Count > 0) 
       { 
        // Populating UserObj 
        bool IsAdmin = false; 
        bool IsMasterAdmin = false; 

        if (Ds.Tables[0].Rows[0]["IsAdmin"].ToString() == "1") 
        { 
         IsAdmin = true; 
        } 
        else 
        { 
         IsAdmin = false; 
        } 

        if (Ds.Tables[0].Rows[0]["IsMasterAdmin"].ToString() == "1") 
        { 
         IsMasterAdmin = true; 
        } 
        else 
        { 
         IsMasterAdmin = false; 
        } 


        ULD = new UserLoginDetails(); 

        ULD.UserId = int.Parse(Ds.Tables[0].Rows[0]["UserId"].ToString()); 
        ULD.IsAdmin = IsAdmin; 
        ULD.IsMasterAdmin = IsMasterAdmin; 
        ULD.UserName = Ds.Tables[0].Rows[0]["FullName"].ToString(); 
        ULD.LocationID = int.Parse(Ds.Tables[0].Rows[0]["LocationID"].ToString()); 
        ULD.FullName = Ds.Tables[0].Rows[0]["FullName"].ToString(); 
        ULD.StatusId = int.Parse(Ds.Tables[0].Rows[0]["StatusId"].ToString()); 
        ULD.Email = Ds.Tables[0].Rows[0]["Email"].ToString(); 
        ULD.CellNo = Ds.Tables[0].Rows[0]["Cell"].ToString(); 
        ULD.CityId = int.Parse(Ds.Tables[0].Rows[0]["CityID"].ToString()); 
        ULD.StateId = int.Parse(Ds.Tables[0].Rows[0]["StateId"].ToString()); 
        ULD.CountryId = int.Parse(Ds.Tables[0].Rows[0]["CountryID"].ToString()); 
       } 

       Session["loggeduserdetails"] = ULD; 

      } 
      return (UserLoginDetails)Session["loggeduserdetails"]; 
     } 
    } 

} 
public class UserLoginDetails 
{ 
    public int UserId = 0; 
    public bool IsAdmin = false; 
    public bool IsMasterAdmin = false; 
    public string UserName = string.Empty; 
    public int LocationID = 0; 
    public string FullName = string.Empty; 
    public int StatusId = 0; 
    public string Email = string.Empty; 
    public string CellNo = string.Empty; 
    public int CityId = 0; 
    public int StateId = 0; 
    public int CountryId = 0; 
}

看起来像你期望得到的数值不是数据块的一个创建一个对象&获取值。 也就是说UserId或CityID不是数值或其他。 我会看看下面的代码行之一：

ULD.UserId = int.Parse(Ds.Tables[0].Rows[0]["UserId"].ToString()); 
ULD.LocationID = int.Parse(Ds.Tables[0].Rows[0]["LocationID"].ToString()); 
ULD.StatusId = int.Parse(Ds.Tables[0].Rows[0]["StatusId"].ToString()); 
ULD.CityId = int.Parse(Ds.Tables[0].Rows[0]["CityID"].ToString()); 
ULD.StateId = int.Parse(Ds.Tables[0].Rows[0]["StateId"].ToString()); 
ULD.CountryId = int.Parse(Ds.Tables[0].Rows[0]["CountryID"].ToString());
