推薦：ASP.NET的高級調(diào)試技巧
　　對于一個項目來說，你不可能通過設定起始頁按F5鍵進行調(diào)試，原因是：各個網(wǎng)頁間的關聯(lián)性太強，要驗證的的東西也很多。在調(diào)試時很難進行(實際上在我做的項目中根本不能進行)。　　那么

login.aspx.cs代碼如下

private void btnLoginBetter_Click(object sender, System.EventArgs e)
{
if (this.tbName.Text == "admin" && this.tbPass.Text == "admin")
{
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,this.tbName.Text,DateTime.Now,DateTime.Now.AddMinutes(30),this.PersistCookie.Checked,"User");
//創(chuàng)建一個驗證票據(jù)

string cookieStr = FormsAuthentication.Encrypt(ticket);
//進行加密

HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,cookieStr);
//創(chuàng)建一個cookie，cookie名為web.config設置的名,值為加密后的數(shù)據(jù)cookieStr,

if (this.PersistCookie.Checked)//判斷用戶是否選中保存cookie

cookie.Expires = ticket.Expiration;//獲取cookie過期時間

cookie.Path = FormsAuthentication.FormsCookiePath;//設置cookie保存路徑

Response.Cookies.Add(cookie);
string strRedirect;
strRedirect = Request["ReturnUrl"];//取出返回url

if (strRedirect == null)
strRedirect = "Default.aspx";
Response.Redirect(strRedirect,true);

}
else
{
Response.Write("<script>alert('帳號或密碼錯誤!');self.location.href='02login.aspx'</script>");
}
}

Default.aspx　HTML代碼

<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<FONT face="宋體">
<asp:Label id="Label1" style="Z-INDEX: 106; LEFT: 224px; POSITION: absolute; TOP: 72px" runat="server">用戶名稱：</asp:Label>
<asp:Label id="Label2" style="Z-INDEX: 102; LEFT: 220px; POSITION: absolute; TOP: 136px" runat="server">身份：</asp:Label>
<asp:Label id="lbUser" style="Z-INDEX: 103; LEFT: 350px; POSITION: absolute; TOP: 79px" runat="server"></asp:Label>
<asp:Label id="lbSf" style="Z-INDEX: 104; LEFT: 355px; POSITION: absolute; TOP: 133px" runat="server"></asp:Label>
<asp:Button id="btnLogout" style="Z-INDEX: 105; LEFT: 261px; POSITION: absolute; TOP: 192px"
runat="server" Text="注銷" Width="101px"></asp:Button></FONT>
</form>
</body>
后置代碼

private void Page_Load(object sender, System.EventArgs e)
{
this.lbUser.Text = User.Identity.Name;
if (User.IsInRole("Admin"))
this.lbSf.Text = "Admin";
else
this.lbSf.Text = "User";
}

分享：結合JavaScript與ASP.NET Web窗體進行程序開發(fā)
ASP.NET為Web程序開發(fā)提供了新的范例。其中包括一系列基于服務器的控件，這些控件類似于HTML窗體中諸如文本框、按鈕等元素。使用這些控件的問題是必須調(diào)用服務器。JavaScript為很多任務提供多種
