Using .NET / C#, how to determine if a network path (eg \\mymachine\\myfolder) is available or not (online or offline)? Is there a way to be notified by WMI of such event?
Thanks!
您可以使用Directory.Exists
检查路径是否存在。
bool folderExists = Directory.Exists(@"\\Path\To\Folder");
Maybe try the Ping class:
http://msdn.microsoft.com/en-us/library/system.net.networkinformation.ping.aspx
It will tell you if a host is available, but I don't know if it will tell you whether a particular share/path is available.
Just try to use it. It will cause an error condition if it isn't. You have to code against that condition anyway: why do it twice?
