问题 I need to implement searching for SD-cards in my program.

But my problem is I have

Have a look at the GetDrives() method on MSDN. 回答2: DriveInfo

问题 Problem description: (occurs at least in VS2005 and VS2008, not tested in VS 2010) If project (e.g. .csproj) or solution file (.sln) is opened from removable drive, and something happens ... seems like if drive is disconnected without safe removing, or if computer crashes or if VS crashes, then project and/or solution files got encrypted. It seems like Visual Studio encrypts project files when opened and only decrypts them when Visual Studio or project is correctly closed. If something

Detect Removable Media Ejection Request in Windows Service

问题 I have a Windows service written in C# with the .NET 2.0 framework that uses the FileSystemWatcher to monitor certain directories for changes. Some of these directories may be on removable media, such as a USB drive. When a new drive is plugged into the system, I get notification through a WMI query and can set up a new FileSystemWatcher. All that works well. The difficulty is that I want the user to be able to eject the drive using the Windows "Safely Remove Hardware" app, but Windows

问题 I'm trying to write a script, which will detect the letter of my USB Removable Drive called "UUI" and then create folder on it. I've written few commands for CMD which, when run separately, work.
