C#获取USB事件API实例分析
本文实例讲述了C#获取USB事件API。分享给大家供大家参考。具体如下：
constintWM_DEVICECHANGE=0x2190;
constintDBT_DEVICEARRIVAL=0x8000;
constintDBT_DEVICEREMOVECOMPLETE=0x8004;
protectedoverridevoidWndProc(refMessagem)
{
try
{
//if(m.Msg==WM_DEVICECHANGE)
//{
switch(m.WParam.ToInt32())
{
caseDBT_DEVICEARRIVAL://U盘插入
DriveInfo[]s=DriveInfo.GetDrives();
foreach(DriveInfodriveins)
{
if(drive.DriveType==DriveType.Removable)
{
Console.WriteLine("USB插入");
break;
}
}
break;
caseDBT_DEVICEREMOVECOMPLETE://U盘卸载
//
Console.WriteLine("USB卸载");
break;
default:
break;
}
//}
}
catch(Exceptionex)
{
MessageBox.Show(ex.Message);
}
base.WndProc(refm);
}
希望本文所述对大家的C#程序设计有所帮助。
