Private Sub TestCase1()
        Dim drive As System.IO.DriveInfo

    For Each drive In System.IO.DriveInfo.GetDrives()
        If drive.DriveType = IO.DriveType.Network Then
            DropDownList1.Items.Add(drive.Name)
        End If
    Next
End Sub

这就是我在C#中的表现：

private void TestCase1()
    {

        //Recurse through the drives on this system and add them to the new DropDownList DropDownList1 if they are a network drive.
        foreach(System.IO.DriveInfo drive in System.IO.DriveInfo.GetDrives())
        {
            //This check ensures that drive is a network drive.
            if (drive.DriveType == System.IO.DriveType.Network)
            {
                //If the drive is a network drive we add it here to a comboBox.
                DropDownList1.Items.Add(drive);
            }
        }
    }
