c# .net 更改标签文本 [英] c# .net change label text

问题描述

您好，我尝试使用此代码，但由于某种原因它不起作用.真的需要帮助.问题是当我进入网站时，标签不会从标签"更改名称.

Hello for I trying to use this code but for some reason it doesn't work. Really need help with this. The problem is that the label doesn't change name from "label" when I enter the site.

<asp:Label ID="Label1" runat="server" Text="label"></asp:Label>


<% 
    Label1.Text = "test";
    if (Request.QueryString["ID"] != null)
    {

        string test = Request.QueryString["ID"];
        Label1.Text = "Du har nu lånat filmen:" + test;
    }

     %>

推荐答案

你应该转换测试类型>>>> test.tostring();

you should convert test type >>>> test.tostring();

把最后一行改成这样:

Label1.Text = "Du har nu lånat filmen:" + test.tostring();
