How to get the list of removable disk in c#?

Question

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.

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);

As for the Saving part, as far as I know I don't think you can restrict where the user is allowed to save to using a SaveFileDialog, but you could complete a check after you have shown the SaveFileDialog.

if(saveFileDialog.ShowDialog() == DialogResult.OK)
{
  if (CheckFilePathIsOfRemovableDisk(saveFileDialog.FileName) == true)
  {
  //carry on with save
  }
  else
  {
  MessageBox.Show("Must save to Removable Disk, location was not valid");
  }
}

OR

The best option would be to create your own Save Dialog, which contains a tree view, only showing the removable drives and their contents for the user to save to! I would recommend this option.

Hope this helps
