MasterPage皮肤的切换关键点

在这里我只做两种皮肤的切换，

1.首先要做两个框架结构相同的母板页；

2.新建内容页，引用默认母板页；

3.在新建页面的.cs文件里写上：

 

Code
protected void Page_PreInit(object sender, EventArgs e)
        {
            if (Request.Cookies["Theme"] != null)
            {
                this.Theme = Request.Cookies["Theme"].Value;
                this.MasterPageFile = "~/" + Request.Cookies["Theme"].Value + ".master";
            }
        }
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack && Request.Cookies["Theme"] != null)
                this.DropDownList1.SelectedValue = Request.Cookies["Theme"].Value;
        }
        protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
        {
            Response.Cookies["Theme"].Value = DropDownList1.SelectedValue;
            Response.Redirect(Request.Url.AbsoluteUri);
        }
