我正在从PHP迁移到ASP.NET/C#.到目前为止一直很好,但我不明白如何在ASP.NET C#类页面中实例化一个类.
例如,我有login.aspx:
<%@ Page Language="C#" Inherits="Portal.LoginService" src="LoginService.cs" %>
<!DOCTYPE html>
<body>
<form runat="server" id="login" name="login">
<p>Username:</p><input type="text" id="username" name="username" runat="server" />
<p>Password:</p><input type="password" id="password" name="password" runat="server" />
<input type="submit" name="submit" OnServerClick="Post_Form" runat="Server" />
</form>
</body>
LoginService.cs:
using System;
using System.Web.UI;
using System.Web.UI.HtmlControls;
namespace Portal {
public class LoginService : Page {
protected HtmlInputControl username, password;
public void Post_Form(object sender, EventArgs e) {
if (username.Value != "" && password.Value != "") {
//LOGIC HERE
//This doesn't work
