準備錯誤我有方法,其檢索其是NTFS的可移動設備的信息:設備不是上DriveInfo.DriveFormat
private void getdriverinfo()
{
// get the usb flash driver
foreach (DriveInfo driveInfo in DriveInfo.GetDrives())
{
if (driveInfo.DriveType == DriveType.Removable && driveInfo.DriveFormat.Equals("NTFS"))
{
comboBox1.Items.Add(driveInfo.Name);
}
}
if (comboBox1.Items.Count == 0)
{
MessageBox.Show("No Removable Device Found , please plug in the USB drive and make sure it is in NTFS format and retry", "No Device Found!", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else if (comboBox1.Items.Count == 1)
{
comboBox1.Text = comboBox1.Items[0].ToString();
}
else
{
MessageBox.Show(comboBox1.Items.Count + " Removable Devices were found , please choose the device you want to protect");
}
}
private void Form1_Load(object sender, EventArgs e)
{
// get the usb flash driver
getdriverinfo();
}
發生此錯誤:
System.IO.IOException:該設備未準備好。
在System.IO .__ Error.WinIOError(的Int32的errorCode,字符串maybeFullPath)
在System.IO .__ Error.WinIODriveError(字符串DRIVENAME,的Int32的errorCode)
在System.IO.DriveInfo.get_DriveFormat ()
在USB_Data_Protector.Form1.getdriverinfo()
這工作得很好我的筆記本電腦沒有任何錯誤。當它在虛擬PC或其他PC上運行時,會顯示此錯誤。
哇,它的工作,但爲什麼?也許是因爲它需要時間做好準備或做什麼? –
