I want to remove a USB drive with the help of C# and When I am using below function, it is able to get drive letter but, when I remove the USB stick and test this function, it doesn’t go to the Exception.
Please, someone, help me!
public void GetDriveLetter()
{
try
{
ManagementObjectSearcher c = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_DiskDrive where InterfaceType='USB'");
foreach (ManagementObject queryObj in managementObjectSearcher.Get())
{
foreach (ManagementObject managementObject in queryObj.GetRelated("Win32_DiskPartition"))
{
foreach (ManagementBaseObject managementBaseObject in managementObject.GetRelated("Win32_LogicalDisk"))
{
usbDriveLetter = String.Format("{0}" + "\\", managementBaseObject["Name"].ToString());
}
}
}
}
catch (ManagementException e)
{
MessageBox.Show(e.StackTrace);
}
}

ManagementObjectSearcher managementObjectSearcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_DiskDrive where InterfaceType='USB'");return (from ManagementObject queryObj in managementObjectSearcher.Get()
from ManagementObject managementObject in queryObj.GetRelated("Win32_DiskPartition")
select managementObject).Select(managementObject => managementObject.GetRelated("Win32_LogicalDisk").Count > 0).FirstOrDefault();
