Question

请问asp.net中如何在后台代码里提交表单

我的代码如下：
Default.aspx内容：
<form id="form1" name="form1" method="post" action="">
<div>
<input id="txtName" name="txtName" type="text" style="width:180px" />
<input name="btnTijiao" type="submit" value="TiJiao" />
</div>
<form id="xixi" runat="server">
<table>
<tr>
<td><asp:Button ID="btnSubmitForm1" runat="server" Text="提交表单form1" OnClick="btnSubmitForm1_Click" /></td>
</tr>
</table>
</form>
Default.aspx.cs内容
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string testName = Request.Params["txtName"];
Response.Write(testName);
}
}
protected void btnSubmitForm1_Click(object sender, EventArgs e)
{

}
我想要在这个btnSubmitForm1_Click函数中提交表单form1，然后Response.Write一下form1中id=txtName的Text控件中的值。
我知道单击form1中TiJiao按钮可以做到这一点，但我不知道怎样才能做到单击“提交表单form1”也能做到这一点
