Programmatically modifying webpart properties

SPSecurity.RunWithElevatedPrivileges(delegate()
{
  // get the site in this context
  using (SPSite SiteCollection = new SPSite("http://localhost"))
  {
    // get the web in this context
    SPWeb myWeb = SiteCollection.OpenWeb("/");
    myWeb.AllowUnsafeUpdates = true;

    SPLimitedWebPartManager mgr = null;
    mgr = myWeb.GetLimitedWebPartManager("default.aspx",PersonalizationScope.Shared);

    foreach (WebPart myWebPart in mgr.WebParts)
    {
     //If this is the webpart we want to modify...
     myWebPart.Title = "New Name" ;
     mgr.SaveChanges(myWebPart);
    }
  }
});
