Windows支持一种特殊的UNC (Universal Naming Convention)路径表示法：\\?\Volume{
获取到磁盘的GUID路径
Caption:盘符
DeviceID:GUID路径
例如：
SelectQuery selectQuery = new
SelectQuery("Win32_Volume");
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(selectQuery);
foreach (ManagementObject disk in searcher.Get())
{
tmpArray.Add(disk.Properties["Caption"].Value.ToString());
tmpArray2.Add(disk.Properties["DeviceID"].Value.ToString());
}
SelectQuery("Win32_Volume");
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(selectQuery);
foreach (ManagementObject disk in searcher.Get())
{
tmpArray.Add(disk.Properties["Caption"].Value.ToString());
tmpArray2.Add(disk.Properties["DeviceID"].Value.ToString());
}
