AutoUpdater.NET is a class library that allows .net developers to easily add auto update functionality to their c# or vb.net projects.
I have added Chinese support. You can add following line before start
AutoUpdaterDotNET.AutoUpdater.CurrentCulture = new System.Globalization.CultureInfo("zh-Hans");
