<div>
using System;
using System.Data;
using System.Configuration;
using  System.Collections;
using System.Web;
using System.Web.Security;
using  System.Web.UI;
using System.Web.UI.WebControls;
using  System.Web.UI.WebControls.WebParts;
using  System.Web.UI.HtmlControls;
using System.Text.RegularExpressions;
using  System.Text;
public partial class Admin_Top : System.Web.UI.Page
{
//ViewState的Html标记的正则表达式
private static readonly Regex viewStateRegex =  new Regex(@"(<input type=""hidden"" name=""__VIEWSTATE"" id=""__VIEWSTATE""  value=""/w(.*)"" />)", RegexOptions.Multiline |  RegexOptions.Compiled);
//</form>标记的正则表达式
private static  readonly Regex endFormRegex = new Regex(@"</form>", RegexOptions.Multiline  | RegexOptions.Compiled);
protected override void Render(HtmlTextWriter writer)
{
System.IO.StringWriter stringWriter = new System.IO.StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
base.Render(htmlWriter);
string html = stringWriter.ToString();
Match  viewStateMatch = viewStateRegex.Match(html);
string viewStateString =  viewStateMatch.Captures[0].Value;//找出ViewState的Html标记
html =  html.Remove(viewStateMatch.Index,  viewStateMatch.Length);//替换掉ViewState的html标记
Match endFormMath = endFormRegex.Match(html,  viewStateMatch.Index);
html = html.Insert(endFormMath.Index,  viewStateString);//将ViewState的Html标记插入到</form>标记之前
writer.Write(html);

}
protected void Page_Load(object  sender, EventArgs e)
{
}
}
</div>
