页面传参的几种方式

页面之间传值的几种方法

1.Get方式

发送页代码:Response.Redirect("WebFormA2.aspx?name=" + TextBox1.Text);

接收页代码:

this.TextBox1.Text = Request["name"];
            //this.TextBox1.Text=Request.Params["name"];
            //this.TextBox1.Text=Request.QueryString["name"];

2.使用内存变量

发送页代码:

Session["name"] = this.TextBox1.Text;
            //Application["name"]=this.TextBox1.Text;

接收页代码:

this.TextBox1.Text = (string)Session["name"];
          //this.TextBox1.Text = (string)Application["name"];

3.Post方式

     发送页代码:

<form id="form1" runat="server" action="WebFormC2.aspx" method="post">
                 <input name="txtname" type="text" value="Andy"/>
                 <input type="submit" value="提交到WebFormC2.aspx"/>   
        </form>

接收页代码:

if (Request.Form["txtname"] != null)
            {
                TextBox1.Text = Request.Form["txtname"];
            }

注意:<form>中不能带runat="server".否则不起作用.

            <form>中的mothod="post"

4.静态变量

         发送页代码:

//定义一个公共变量
                 public static string str = "";
                 protected void Button1_Click(object sender, EventArgs e)
                {
                     str = this.TextBox1.Text;
                     Response.Redirect("WebFormD2.aspx");
                 }

接收页代码:  this.TextBox1.Text = WebFormD1.str;

5.Context.Handler获取控件

        发送页代码:

<asp:TextBox ID="TextBox1" Text="Andy" runat="server"></asp:TextBox>
               <asp:Button ID="Button1" runat="server" Text="进入WebFormE2.aspx" OnClick="Button1_Click" />

//Button1_Click事件代码

Response.Redirect("WebFormE2.aspx");

接收页面代码:

//获取post过来的页面对象
            if (Context.Handler is WebFormE1)
            {
                //取得页面对象
                WebFormE1 poster = (WebFormE1)Context.Handler;

//取得控件               
                this.TextBox1.Text = ((TextBox)poster.FindControl("TextBox1")).Text;
                //this.TextBox1.Text = poster.TextBox1.Text;
            }

6.Context.Handler获取公共变量

        发送页代码:

//定义一个公共变量
             public string strname = "Andy";
             protected void Button1_Click(object sender, EventArgs e)
            {            
                 Response.Redirect("WebFormE2.aspx");

}

接收页代码:

//获取post过来的页面对象
            if (Context.Handler is WebFormF1)
            {
                //取得页面对象
                WebFormF1 poster = (WebFormF1)Context.Handler;
                this.TextBox1.Text = poster.strname;
            }

7.Context.items变量

     发送页代码:

protected void Button1_Click(object sender, EventArgs e)
            {
                  Context.Items["name"] = TextBox1.Text;
                  Server.Transfer("WebFormG2.aspx");
             }

接收页代码:

//获取post过来的页面对象
            if (Context.Handler is WebFormG1)
            {
                this.TextBox1.Text = Context.Items["name"].ToString();
            }
