简洁代码如下：
const int WM_DEVICECHANGE = 0x2190;
const int DBT_DEVICEARRIVAL = 0x8000;
const int DBT_DEVICEREMOVECOMPLETE = 0x8004;
protected override void WndProc(ref Message m)
{
ManagementClass DiskClass = new ManagementClass(@"Win32_Diskdrive");
try
{
if (m.WParam.ToInt32() == DBT_DEVICEARRIVAL)
{
ManagementObjectCollection Moc =DiskClass.GetInstances();
}
if (m.WParam.ToInt32() == DBT_DEVICEREMOVECOMPLETE)
{
ManagementObjectCollection Moc= DiskClass.GetInstances();
}
}
catch (Exception ex){}
出错如下：
