C# How to know if a given path represents a root drive?

阅读更多关于 C# How to know if a given path represents a root drive?

问题 How can I know if a given directory is a root drive? (aside from checking if its path equals to "A:", "B:", "C:", etc.) 回答1: Check if DirectoryInfo.Parent is null or not DirectoryInfo d = new DirectoryInfo(""); if(d.Parent == null) { IsRoot = true; } you can also get the root by using DirectoryInfo.Root; 回答2: It's much more complicated than checking the Parent property. Determining Whether a Directory Is a Mounted Folder One approach would be to see if GetVolumeNameForVolumeMountPoint

阅读更多关于 Android, Google Drive: Google consent screen freezes

问题 I've upgraded my app to the Google Drive REST API and its Java wrappers, as described here: https://developers.google.com/drive/android/deprecation My code is very close to the official demo app provided by Google. I also cross-checked with other code examples I've found. The Google Drive API upgrade itself was successful, but now there are very few users that cannot log-in anymore. The Google consent screen displays a white box and the circle is rotating. No information is displayed at all.

Today after I updated my Drive API to V3, I dint find any method to find the parent of the selected file . Is the rest endpoint to fetch json related to parent's info changed?
