我正在实现一个小型网站，将从用户那里获取输入并与c#中的数据库进行交互，但问题是代码后台（即.aspx.cs文件中的代码）不会读取.aspx文件中的任何元素，尽管我已经在指令中将.aspx文件的继承属性赋值为.aspx.cs文件。
这是HomePage.aspx文件
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="HomePage.aspx.cs" Inherits="HomePage.aspx.cs" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="lbl_username" runat="server" Text="Username: "></asp:Label>
<asp:TextBox ID="txt_username" runat="server"></asp:TextBox>
<asp:Label ID="lbl_password" runat="server" Text="Password: "></asp:Label>
<asp:TextBox ID="txt_password" runat="server" TextMode="Password"></asp:TextBox>
<asp:Button ID="btn_login" runat="server" Text="Login" onclick="login" />
</div>
</form>
</body>
</html>
这是HomePage.aspx.cs文件

{
string connStr = ConfigurationManager.ConnectionStrings["MyDbConn"].ToString();
SqlConnection conn = new SqlConnection(connStr);
SqlCommand cmd = new SqlCommand("loginProcedure", conn);
cmd.CommandType = CommandType.StoredProcedure;
string username = txt_username.Text;
string password = txt_password.Text;
cmd.Parameters.Add(new SqlParameter("@username", username));
SqlParameter name = cmd.Parameters.Add("@password", SqlDbType.VarChar, 50);
name.Value = password;
// output parm
SqlParameter count = cmd.Parameters.Add("@count", SqlDbType.Int);
count.Direction = ParameterDirection.Output;
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
if (count.Value.ToString().Equals("1"))
{
Response.Write("Passed");
}
else
{
Response.Write("Failed");
}
}
}
我遇到了一个错误，提示无法加载类型“HomePage.aspx.cs”，那么我该如何处理这种情况？
