Question

c#中，方法的参数传递有几种？懂的简单说一下吧

Answer 1

1. 通过URL链接地址传递 Request.Redirect("Default2.aspx?username=honge");

2. 通过post方式:

   <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="username" runat="server"></asp:TextBox>
   </div>
       </form>
   receive.aspx
   string username = Ruquest.Form["receive"];

3. 通过session

   send.aspx:
     protected void Button1_Click(object sender, EventArgs e)
       {
           Session["username"] = "honge";
           Request.Redirect("Default2.aspx");
       }
    receive.aspx:
    string username = Session["username"];这样可以得到参数值

   常用的就是这种
