c# Web表单处理

我对使用c#相当陌生，一旦单击按钮，我就会遇到使用c#处理表单数据的问题。基本上我要做的是捕获用户的信息，一旦表单按钮被单击，将其分配给会话，然后在另一个页面上显示它。下面是我的c#代码:

using System;
using System.Web.UI;
public partial class Data : Page
{
    protected void btnSubmit(object sender, EventArgs e)
    {
        string name = Request.Form["username"];
        if (string.IsNullOrEmpty(name))
        {
            // string usr_err = "You did not supply a username???";
            return;
        }
        // make the string uppercase
        string upperCase = name.ToUpper();
        string greeting = "Welcome " + upperCase + "! Did you know that October is called Oktober in German?";
        Session["username"] = upperCase;
        Session["greeting"] = greeting;
        Response.Redirect("test.aspx", false);
    }
}
这是我的html (login.apsx): 
    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Data.cs" Inherits="CS" %>
<!doctype html>

我遇到了这个编译错误，虽然我不知道为什么:

Line 2:  using System.Web.UI;
Line 3:  
Line 4:  public partial class Data : Page
Line 5:  {
Line 6:      protected void btnSubmit(object sender, EventArgs e)
(Line 4 is where the error occurs).

如果有帮助，下面是通过编译器提供的更多细节:

描述:在编译服务此请求所需的资源期间发生错误。请查看以下具体的错误细节，并适当地修改源代码。

编译器错误消息:asp.net: Make sure .定义的类此代码文件匹配'inherits'属性，并进行扩展正确的基类(例如Page或UserControl)

任何帮助都将不胜感激，

谢谢!

查看下面的错误消息，它正确地说明了问题所在。

编译器错误消息:asp.net: Make sure .定义的类此代码文件匹配'inherits'属性，并进行扩展正确的基类(例如Page或UserControl)

当前为CodeFile="Data.cs" Inherits="CS"的Inherit属性也应该指向Data，如

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Data.cs" Inherits="Data" %>

(OR)如果您定义了一个名称空间，那么使用该名称空间进行限定，如

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Data.cs" Inherits="MyNamespace.Data" %>
