removable-drive

I want to get the list of removable disk in c#. I want to skip the local drives. Because i want the user to save the file only in removable disk. Lloyd Powell You will need to reference System.IO for this method. var driveList = DriveInfo.GetDrives(); foreach (DriveInfo drive in driveList) { if (drive .DriveType == DriveType.Removable) { //Add to RemovableDrive list or whatever activity you want } } Or for the LINQ fans: var driveList = DriveInfo.GetDrives().Where(d => d.DriveType == DriveType.Removable); Added As for the Saving part, as far as I know I don't think you can restrict where the

Do you know what is the API, or sequence of API calls that windows uses to accomplish the "Eject" function which is available on the shell context menu for removable volumes? So far I've tried two things: using CM_Request_Device_Eject , I enumerate the removable disks (using the SetupDiXXX APIs ), find the one that I'm interested in, walk the device manager hierarchy (using CM_XXX APIs ) and finally call CM_Request_Device_Eject on the devInst of the device I'm interesed in. This works in the sense that it does remove the volumes from My Computer and makes the device "safe to remove" (ready to

I am currently using WM_DEVICECHANGE to be notified when new USB drives are connected to the computer. This works great for devices like thumb-drives where as soon as the device arrives it is ready to have files read from it. For devices like SD card readers it does not because the message is sent out once when the device is connected but no message is sent when a user actually inserts a card into the device. Is it possible to detect the insertion of new media into an existing USB device without having to use polling? I just did this a few weeks ago. Technically speaking the

I am using Environment.GetLogicalDrives(); to get a list of drives. I remember in c++ i could use GetDriveType to find if the device was CD, removable, flash, etc and i am thinking i want to put a filter in my app to only show CD and removable on default. What is the GetDriveType equivalent in C#? google only showed me hacks to use the c++ call. Yes, the framework includes a DriveType enumeration used by the DriveInfo class. Have a look at the GetDrives() method on MSDN. DriveInfo is the class you are looking for. 来源： https://stackoverflow.com/questions/623254/getdrivetype-in-c-or-find-out-if
