我的第一个CS页面是

My first cs page is

protected void Button1_Click(object sender, EventArgs e)
    {
        ArrayList myAL1 = new ArrayList();
        myAL1.Add(txtId.Text.ToString());
        myAL1.Add(txtName.Text.ToString());
        string items = String.Join(",", ((string[])myAL1.ToArray(typeof(String))));
        string url = "ReceiveValueOfTextBoxSendingInLoop.aspx?items=" + items;
        Response.Redirect(url);
    }

我的第二个CS代码是

My second cs code is

protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.QueryString["items"].ToString() != null)
        {

            string[] items = Request.QueryString["items"].ToString().Split('','');
            ArrayList al = new ArrayList();
            foreach (string item in items)
            {
                al.Add(item);
                string ss = al[item].ToString();
                Response.Write(ss);
            }
            //string ss = al[0].ToString();
            //string ss1 = al[1].ToString();
           
          //  Response.Write(ss);
           // Response.Write(ss1);
        }

    }

推荐答案

请尝试一下....

string[] items = Request.QueryString["items"].ToString().Split(',');
                  ArrayList al = new ArrayList();
                  foreach (string item in items)
                  {
                        al.Add(item);
                        string ss = al[0].ToString();
                        string ss1 = al[1].ToString();
                        Response.Write(ss);
                  }

在您的CS页面中添加以下名称空间

Add the below namespace in your cs pages

using System.Collections;

string ss = al[item].ToString();

您试图将string变量用作需要整数的索引.

[edit]
您应该使用 Add() [ ^ ]方法.

You are trying to use a string variable as an index where an integer is required.

[edit]
You should use the return value from the Add()[^] method.
