How to judge a computer offline with C#?

thanks very much!

Hi steven99, I am not sure what exactly you are looking for but checkout WMI under the System.Management namespace. There are a bunch of Win32 classes that you can use to query the state of a machine remotely or locally. Search the csharp corner website for some sample code. If you need list of WMI object that you can query checkout this link: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/wmi_classes.asp Hope that helps.
