我尝试过：

What I have tried:

  DropDownList1.Items.Add("AC");
            DropDownList1.Items.Add("NON-AC");
            DropDownList1.Items.Add("DELUX");

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            if (TextBox1.Text!= "")
            {
                string s = TextBox1.Text;
                Response.Redirect("WebForm2.aspx?val=" + TextBox1.Text);
            }

in aspx2 

  protected void Page_Load(object sender, EventArgs e)
        {
           


            Button b = new Button();
            b.Text =Request.QueryString["val"];
           Panel1.Controls.Add(b);

推荐答案

试试

try

protected void Button1_Click(object sender, EventArgs e)
       {
           string value = DropDownList1.SelectedItem.Value;
           Response.Redirect("WebForm2.aspx?val=" + value);

       }
