You can make use of coditional comments and javascript to do that.
Something like following should work-

HTML

<!doctype html>
<!--[if (gt IE 8)|!(IE)]> <html class="not_supported"> <![endif]-->
<!--[if (lt IE 8)|(IE 8)]><!--> <html class=""> <!--<![endif]-->
<head>

Javascript:

JavaScript

(function ($) {
    "use strict";

    if ($('html').is('not_supported')) {
        alert("This browser version is not supported");
        window.location.href = 'http://www.google.com';
    }
}(jQuery));

Hope, it helps :)
Let me know if it doesn't work.

you can do this way .

C#

private float getInternetExplorerVersion()
{
  // Returns the version of Internet Explorer or a -1
  // (indicating the use of another browser).
  float rv = -1;
  System.Web.HttpBrowserCapabilities browser = Request.Browser;
  if (browser.Browser == "IE")
    rv = (float)(browser.MajorVersion + browser.MinorVersion);
  return rv;
}

private void Page_Load(object sender, System.EventArgs e)
{
  string msg;
  double ver = getInternetExplorerVersion();
  if (ver > 0.0)
  {
    if (ver >= 8.0) 
      msg = "You're using a recent version of Internet Explorer.";
    else
      msg = "You should upgrade your  Internet Explorer.";
  } 
  else
    msg = "You're not allowed other browser.";

  Label1.Text = msg;
}
