問題出現
在VisualStudio創建Web窗體並對頁面內容進行刪改時，出現這樣的問題
“類型“TextBox”的控件“TextBox1”必須放在具有 runat=server 的窗體標記內。”
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="index.aspx.cs" Inherits="貸款計算器.index" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<asp:Label ID="Label1" runat="server" Text="label1"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Label ID="Label2" runat="server" Text="label2"></asp:Label>
</body>
</html>
