<form id="form1" method="get" runat="server" > //注意 method="get"

public string mValue = "i'm transfer data";
protected void Page_Load(object sender, EventArgs e)
{
Response.Write(txtName.Value);
}
protected void Button1_Click(object sender, EventArgs e)
{
Server.Transfer("Default4.aspx",true);
}
}
----------------------------
public partial class Study_Default4 : System.Web.UI.Page //Default4.aspx.cs
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Study_Default3 obj = (Study_Default3)this.Context.Handler;
Response.Write(obj.mValue);
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write(Request.QueryString["txtName"].ToString());
//问题？这里可以得到 default3(method="get")的txtName 如果method="post" 能得到txtName 的值吗 如何得到
}
}
[解决办法]
注意一下:
if(Request["txtName"]!= null)
txtName是你的Input控件的name,要一致
<input type="text" id="txtName" value="hello" runat="server" />
