问题 I need to determine how much free space there is on a Windows CE device, to conditionally determine whether a particular operation should proceed. I thought Ken Blanco's answer here (which bears a striking similarity to the example yonder) would work, which I adapted as: internal static bool EnoughStorageSpace(long spaceNeeded) { DriveInfo[] allDrives = DriveInfo.GetDrives(); long freeSpace = 0; foreach (DriveInfo di in allDrives) { if (di.IsReady) { freeSpace = di.AvailableFreeSpace; } }

问题 UPDATE : This issue doesn't appear on Android devices I've tested. It returns good values. Would really appreciate any pointers on this matter. I am having trouble getting the correct AvailableFreeSpace values from my Mac desktop computer. I am working with Unity3D C#, and am using the following code : DriveInfo[] drives = DriveInfo.GetDrives(); foreach(DriveInfo drive in drives) { if (drive.IsReady) { Debug.Log(drive.Name); Debug.Log(drive.AvailableFreeSpace); Debug.Log(drive.TotalFreeSpace)

问题 I'm creating a WPF app that among other things should check for the existence of several mapped drives. The code is straightforward: DriveInfo[] systemDrives = DriveInfo.GetDrives(); foreach (DriveInfo i in systemDrives) { if ((i.Name.Contains("V")) && (i.IsReady)) { result = true; break; } } The mapped drives are mapped fro all users. The code above works fine when run as a regular user, however is Visual Studio 2010 is run as administrator the GetDrives method only returns the Fixed drives

ORIGINAL QUESTION : I am working in Unity C#. I'd like to get the free available disk space on the device I'm using. I've tried using System.IO.DriveInfo but it doesn't work

问题 I am working on a small utility where I would like to change the volume label on flash drives that are connected to the computer. I know that DriveInfo is capable of doing it but I am at a loss as for how to accomplish it. If anyone has a code sample I would really appreciate it. Here is what i currently have: DriveInfo[] allDrives = DriveInfo.GetDrives(); foreach (DriveInfo d in allDrives) { if (d.IsReady && d.DriveType == DriveType.Removable) { //set volume label here } } 回答1: Thanks James!
