ASP.NET跨页面传值技巧

今天TM群里有人问起关于页面传值的方法,又引发了一场讨论.看来这个还是有很多人关注的,因此我就我个人观点做了些总结,希望对大家有所帮助.1.  使用QueryString变量QueryString是一种非?lt;虻サ拇捣绞?他可以将传送的值显示在浏览器的地址栏中.如果是传递一个或多个安全性要求不高或是结构简单的数值时,可以使用这个方法.但是对于传递数组或对象的话,就不能用这个方法了.下面是一个例子：a.aspx的C#代码private void Button1_Click( object sender, System.EventArgs e ){    string s_url;    s_url = "b.aspx?name=" + Label1.Text;    Response.Redirect( s_url );}b.aspx中C#代码private void Page_Load( object sender, EventArgs e ){    Label2.Text = Request.QueryString["name"];}2.  使用Application 对象变量Application对象的作用范围是整个全局,也就是说对所有用户都有效.其常用的方法用Lock和UnLock.a.aspx的C#代码private void Button1_Click( object sender, System.EventArgs e ){    Application["name"] = Label1.Text;    Server.Transfer( "b.aspx" );}b.aspx中C#代码private void Page_Load( object sender, EventArgs e ){    string name;    Application.Lock( );    name = Application["name"].ToString( );    Application.UnLock( );}3.  使用Session变量想必这个肯定是大家使用中最?lt;挠梅?其操作与Application类似,作用于用户个人,所以,过量的存储会导致服务器内存资源的耗? ?a.aspx的C#代码private void Button1_Click( object sender, System.EventArgs e ){    Session["name"] = Label.Text;}b.aspx中C#代码private void Page_Load( object sender, EventArgs e ){    string name;    name = Session["name"].ToString( );}4.  使用Cookie对象变量这个也是大家常使用的方法,与Session一样,其是什对每一个用户而言的,但是有个本质的区别,即Cookie是存放在客户端的,而session是存放在服务器端的.而且Cookie的使用要配合asp.NET内置对象Request来使用.a.aspx的C#代码private void Button1_Click( object sender, System.EventArgs e ){    HttpCookie cookie_name = new HttpCookie( "name" );    cookie_name.Value = Label1.Text;    Reponse.AppendCookie( cookie_name );    Server.Transfer( "b.aspx" );}b.aspx中C#代码private void Page_Load( object sender, EventArgs e ){    string name;    name = Request.Cookie["name"].Value.ToString( );}5.  使用Server.Transfer方法这个才可以说是面象对象开发所使用的方法,其使用Server.Transfer方法把流程从当前页面引导到另一个页面中,新的页面使用前一个页面的应答流,所以这个方法是完全面象对象的,简洁有效.a.aspx的C#代码public string Name{    get    {        return Label1.Text;    }}private void Button1_Click( object sender, System.EventArgs e ){    Server.Transfer( "b.aspx" );}b.aspx中C#代码private void Page_Load( object sender, EventArgs e ){    a newWeb;    //实例a窗体    newWeb = ( source )Context.Handler;        string name;    name = newWeb.Name;
