// This code will not execute when the application is reactivated

{
if (e.Result == null)
{
return;
}
System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
//string version = System.Reflection.Assembly.GetExecutingAssembly().FullName;
//获取程序集的版本号，然后去掉.得到数字对比大小
string version = assembly.GetCustomAttributes(false).OfType<System.Reflection.AssemblyFileVersionAttribute>().First().Version;
if (int.Parse(e.Result.Ver) > int.Parse(version.Replace(".", "")))
