WebForm中 页面传参的总结

Posted 2020-09-15

1.Form表单传递(get/post)  

  前台：

 1             姓名：<input id="TxtValue" name="TxtName" type="text" /><br />
 2             年龄：<input id="AgeValue" name="AgeValue" type="text" /><br />
 3             性别：<input type="radio" name="sex" value="男" />男
 4                  <input type="radio" name="sex" value="女" />女
 5             爱好：<select id="SltLike" name="SltLike">
 6                      <option value="like1">打球</option>
 7                      <option value="like2">睡觉</option>
 8                      <option value="like3">上网</option>
 9                  </select><br />


10             <input type="submit" value="提交" />

 

后台使用一般处理程序接收：

      
            string Name = context.Request["TxtName"].ToString();
            string Age = context.Request["AgeValue"].ToString();
            string Sex = context.Request["sex"].ToString();
            string Like = context.Request["SltLike"].ToString();

2.使用URL传值

   前台：

   <%---------- URL  传参----------------%>
   <a href="WebForm1.aspx?Value1=123&Value2=txt">URL传参</a><br />
   <asp:Button ID="Button1" PostBackUrl="WebForm1.aspx?Userid=1" runat="server" Text="Post页面传值" Height="27px" OnClick="Button1_Click" /><br />

   后台：

 

 string Value1 = Request.QueryString["Value1"];
 string Value2 = Request.QueryString["Value2"];

 

 

 

3.Session传值

 前台：

1   <%---------- Session  传参----------------%>
2   <asp:Button ID="Button2" runat="server" Text="读取Session" OnClick="Button2_Click" /><br />

后台：

 //写入Session
 Session["SessionValue"] = "我是Session中的值";

 

 //读取
string Session_Str = Session["SessionValue"].ToString();
 Response.Write(Session_Str);

4.Cookie传值

前台：

 <%---------- Cookie  传参----------------%>
 <asp:Button ID="Button3" runat="server" Text="读取Cookies" OnClick="Button3_Click" /><br />

后台：

 //写入cookie
  HttpCookie cook = new HttpCookie("Cook", "我是Cookie中的值");
  Response.Cookies.Add(cook);

//读取Cookie
 HttpCookie cook = Request.Cookies["Cook"];
 Response.Write(cook.Value);

5.Application传值

前台：

 <%---------- Application  传参----------------%>
 <asp:Button ID="Button4" runat="server" Text="读取Application" OnClick="Button4_Click" /><br />

后台：
