同一页面.aspx与.aspx.cs之间参数传递
1. .aspx.cs接收.aspx的参数:由于.aspx和.aspx.cs为继承关系,所以.aspx.cs可以直接对.aspx中的ID进行值提取,具体语句为string b = a.text; 其中a为.aspx中的文本框的ID;
2. .aspx接收.aspx.cs的变量:将.aspx.cs的变量设为全局变量,在.aspx中直接引用<%=a %>,这里a为.aspx.cs
中声明的全局变量;
不同页面之间的参数传递
1.URL传递参数方法,有两种方法:
第一种:send.aspx
<a href=receive.aspx?a=b></a>
receive.aspx.cs
string c = Request.QueryString["a"];
第二种:send.aspx.cs: protected void Button1_Click(object sender, EventArgs e) { Request.Redirect("receive.aspx?a=b"); } receive.aspx.cs: string username = Request.QueryString["username"];
2. Form表单POST方法
send.aspx <form id="form1" runat="server" action="receive.aspx" method=post> <div> <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /> <asp:TextBox ID="a" runat="server"></asp:TextBox> </div> </form> receive.aspx.cs string b = Ruquest.Form["a"];
3.通过session方法传递参数
send.aspx.cs: protected void Button1_Click(object sender, EventArgs e) { Session["username"] = "a"; Request.Redirect("receive.aspx"); } receive.aspx: string username = Session["username"];
