CS0103 名称 'txtname' 在当前上下文中不存在

Question

我得到 'txtname'、'txthours'、'txtrate'，并且 'textgrosspay' 在当前上下文中不存在。错误代码是 CS0103。我也将设计师的文本框中的文字与这些文字进行了匹配。任何帮助表示赞赏。

这张图片显示了我的网络表单的设计部分：

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Grosspayapp : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Compute_Click(object sender, EventArgs e)
    {
        String name;
        String shours, srate;
        int hours;
        double rate, grosspay;

        name = txtname.Text;

        shours = txthours.Text;
        hours = Convert.ToInt32(shours);

        srate = txtrate.Text;
        rate = Convert.ToDouble(srate);

        grosspay = hours * rate;

        txtgrosspay.Text = grosspay.ToString();

    }

}

源代码是
