asp.net页面间传值的几种方法

表单提交

传送页面代码

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>表单提交</title>

     <script type="text/javascript" language="javascript">

            function post()

            {      

                forPost.action="DestinationPage.aspx";        

                forPost.submit();

            } 

    </script>

</head>

<body>

        <form id="forPost"  method="post">

         方式一：表单提交<br />

         <input type="text" id="SourceData2" runat="server"/>

         <input type="button" id="btnTransfer1" value="提交" onclick="post();" />             

        </form>   

</body>

</html>

接收页面代码

protected void Page_Load(object sender, EventArgs e)

{

    string a = Request.Form["SourceData2"].ToString();

    txt1.Value = a;              

}

QueryString传值

传送页面代码

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>QueryString</title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <input type="text" id="txt1" runat="server" />

        <input type="text" id="txt2" runat="server" />

        <input type="button" id="btn1" value="提交" runat="server" onserverclick="btn1_ServerClick" />

    </div>

    </form>

</body>

</html>

    protected void btn1_ServerClick(object sender, EventArgs e)

    {

        string aa = txt1.Value;

        string bb = txt2.Value;

        string url = "DestinationPage5.aspx?parameter1=" + aa + "&parameter2=" + bb;

        Response.Redirect(url, false);      

    }

接收页面代码

protected void Page_Load(object sender, EventArgs e)

    {

        txt1.Value = Request.QueryString["parameter1"].ToString();

        txt2.Value = Request.QueryString["parameter2"].ToString();

    }

链接地址传值

传送页面代码

<a href="DestinationPage6.aspx?param1=1111&param2=2222">跳转</a>

接收页面代码

protected void Page_Load(object sender, EventArgs e)

    {       

        txt1.Value = Request["param1"];

        txt2.Value = Request["param2"];

}

Context传值

通过Context传值，在传送页面之前，将需要传递到其他页面的值存在Context中。

传送页面代码

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>Context</title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <input type="text" id="txt1" runat="server" />

        <input type="button" id="btn1" value="提交" runat="server" onserverclick="btn1_ServerClick" />

    </div>

    </form>

</body>

</html>

protected void btn1_ServerClick(object sender, EventArgs e)

    {

        Context.Items["value"] = txt1.Value;

        Server.Transfer("DestinationPage3.aspx");      

    }

接收页面代码

protected void Page_Load(object sender, EventArgs e)

    {

        string a = Context.Items["value"].ToString();

        txt1.Value = a;

    }

Server.Transfer传值

传送页面代码

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>Server.Transfer</title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <input type="text" id="txt1" runat="server" />

        <input type="button" id="btn1" value="提交" runat="server" onserverclick="btn1_ServerClick" />

    </div>

    </form>

</body>

</html>

Session传值

通过Session取值，在一个页面中赋值，在其他页面中共享。为避免造成Session值的混乱无序，应尽量少用Session传非公共的变量。Session比较适合用来保存一些公共变量。

Application传值

此种方法不常使用，因为Application在一个应用程序域范围共享，所有用户可以改变及设置其值，故只应用于计数器等需要全局变量的地方。

传送页面代码

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Application</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <input type="text" id="txt1" runat="server" />        
        <input type="button" id="btn1" value="提交" runat="server" onserverclick="btn1_ServerClick" />
    </div>
    </form>
</body>
</html>

protected void btn1_ServerClick(object sender, EventArgs e)
    {
        string aa = txt1.Value;
        Application["param1"] = aa;
        string url = "DestinationPage7.aspx";
        Response.Redirect(url, false);
    }
