WebForm 超链接传值

以Car表增删改为例

Car.aspx

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Literal ID="LiteralCar" runat="server"></asp:Literal>       
    </div>
    </form>
</body>

Car.aspx.cs

 protected void Page_Load(object sender, EventArgs e)
    {
        List<Car> list = new CarBF().Select();
        string s = "<center><table width='40%' border='1'><tr><td>编号</td><td>名称</td><td>价格</td><td>操作</td></tr>";
        foreach (Car data in list)
        {
            s += "<tr><td>"+data.Code+"</td><td><a href='XiangXi.aspx?Code= "+ data.Code+"'>"+data.Name+"</a></td><td>"+data.Price+"</td><td><a href='Delete.aspx?code="+data.Code+"'>删除</a></td></tr>";
        }
        s += "</table></center>";
        LiteralCar.Text = s;
    }

<a href='XiangXi.aspx?Code= "+ data.Code+"'>"+data.Name+"</a> xxx.aspx?xx=+值  在对应页面Request["xx"].ToString()接收

XiangXi.aspx

<body>
    <form id="form1" runat="server">
    <div>
        <center>
       <table>
           <tr>
