.aspx文件中代碼如下:
<asp:TextBox ID="txtUser_Id" runat="server" MaxLength="4" Width="120px" BorderColor="LightSlateGray" BorderWidth="1px"></asp:TextBox>
<asp:ImageButton ID="btnInsert" runat="server" ImageUrl="~/Images/Login.GIF" OnClick="btnInsert_Click" />
<asp:CheckBox ID="cbxRemeberUser" runat="server" Text="記住用戶名" Font-Size="Small" ForeColor="gray"/>
.aspx.cs文件中代碼如下:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.txtUser_Id.Focus();
if (!Object.Equals(Request.Cookies["UserID"], null))
{ //創建一個Cookie對象，實現記住用戶名
HttpCookie readcookie = Request.Cookies["UserID"];
this.txtUser_Id.Text = readcookie.Value;
}
}
}
private void CreateCookie()
{
//創建一個Cookie對象
HttpCookie cookie = new HttpCookie("UserID");
//判斷Checkbox控件是否被選中
if (this.cbxRemeberUser.Checked)
{
//將用戶編號存儲到創建的Cookie對象中
cookie.Value = this.txtUser_Id.Text;
}
//獲取創建的Cookie對象的過期時間
cookie.Expires = DateTime.MaxValue;
//將創建的Cookie對象添加到內部Cookie集合中
Response.AppendCookie(cookie); }
protected void btnInsert_Click(object sender, ImageClickEventArgs e)
{
if (object.Equals(Request.Cookies["UserID"], null))
{
//調用自定義方法 CreateCookie() 存儲用戶名
CreateCookie();
}
else
{
CreateCookie();
}
