aspx不显示ViewState的实例

复制代码 代码如下:

  System.IO.StringWriter html = new System.IO.StringWriter();

  System.Web.UI.HtmlTextWriter tw = new System.Web.UI.HtmlTextWriter(html);

  base.Render(tw);

  string Temp = html.ToString();

  string s1 = string.Empty, s2 = string.Empty, s3 = string.Empty, s4 = string.Empty, s5 = string.Empty, s6 = string.Empty;

  int i = 0;

  int j = 0;

  i = Temp.IndexOf("<form");

  if (i > 0)

  {

  j = Temp.IndexOf(">", i);

  s1 = Temp.Substring(0, i);

  s2 = Temp.Substring(j + 1, Temp.Length - j - 1);

  }

  i = s2.IndexOf("<input type=\"hidden\" name=\"__VIEWSTATE\" id=\"__VIEWSTATE\"");

  if (i > 0)

  {

  j = s2.IndexOf(">", i);

  s3 = s2.Substring(0, i);

  s4 = s2.Substring(j + 1, s2.Length - j - 1);

  }

  i = s4.IndexOf("<input type=\"hidden\" name=\"__EVENTVALIDATION\" id=\"__EVENTVALIDATION\"");

  if (i > 0)

  {

  j = s4.IndexOf(">", i);

  s5 = s4.Substring(0, i);

  s6 = s4.Substring(j + 1, s4.Length - j - 1);

  Temp = s1 + s3 + s5 + s6;

  }

  else

  {

  Temp = s1 + s3 + s4;

  }

  Temp = Temp.Replace("</form>", "");

  Temp = Temp.Replace("\r\n", "");

  tw.Close();

  Response.Write(Temp);
