将字符串数组从一个ASP页传递到另一页 [英] Passing a String Array from one ASP page to another

问题描述

我正在尝试将DropDownList从一页传递到另一页.
来自第一个ASPX页的代码是:

I am trying to pass a DropDownList from one page to the other.
The code from the first ASPX page is:

if (validLogon)

       {
           Session["FacilityNames"] = FacilityNames;
           Session["User"] = txtUser;
           Response.Redirect("Default2.aspx");
       }

其中FacilityName是字符串数组
来自第二个ASPX页面的代码是:

Where FacilityName is a string array
The code from the Second ASPX page is:

public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string fac = (string)Session["FacilityNames"].ToString();

           foreach (var sss in fac)
        {
            ddlFacilities.Items.Add(sss.ToString());
        }

fac字符串变量填充为"System String []而不是从首页指定的字符串数组.

The fac string variable is populated with "System String[] instead of the string array specified from the first page.

推荐答案

ToString()是会话的ToString重载.因此，如下所示.

ToString() is overload of ToString for session. so write like below.

protected void Page_Load(object sender, EventArgs e)
    {
        string fac = (string)Session["FacilityNames"];

           foreach (var sss in fac)
        {
            ddlFacilities.Items.Add(sss.ToString());
        }
