我需要我的程序只能使用某些USB闪存驱动器（来自单个制造商）而忽略所有其他USB闪存驱动器（来自任何其他制造商）。
是否可以使用.NET 2.0检查Windows上是否插入了特定的USB卡？如何？
如果我通过WMI找到它，我可以以某种方式确定USB驱动器所在的驱动器号吗？
解决方案
编辑：添加了打印硬盘信件的代码。
检查此示例是否适合您。它使用WMI。
Console.WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]);
...
Console.WriteLine(" Name: {0}", c["Name"]); // here it will print drive letter
完整的代码示例：
namespace WMISample
{
using System;
using System.Management;
public class MyWMIQuery
{
public static void Main()
{
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_DiskDrive");
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("DeviceID: {0}", queryObj["DeviceID"]);
Console.WriteLine("PNPDeviceID: {0}", queryObj["PNPDeviceID"]);
Console.WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]);
Console.WriteLine("Model: {0}", queryObj["Model"]);
foreach (ManagementObject b in queryObj.GetRelated("Win32_DiskPartition"))
{
Console.WriteLine(" Name: {0}", b["Name"]);
foreach (ManagementBaseObject c in b.GetRelated("Win32_LogicalDisk"))
{
Console.WriteLine(" Name: {0}", c["Name"]); // here it will print drive letter
}
}
// ...
Console.WriteLine("--------------------------------------------");
}
}
catch (ManagementException e)
{
Console.WriteLine(e.StackTrace);
}
Console.ReadLine();
}
}
}
我认为这些属性可以帮助您区分原装USB驱动器与其他驱动器。使用多个笔式驱动器进行测试，以检查值是否相同。请在此处查看 Win32_DiskDrive 属性的完整参考：

其他提示
您可以使用非托管的Win32 API调用来处理此问题。
http://www.codeproject.com/KB/system/EnumDeviceProperties.aspx
通过Win32 CM_（设备管理）或WMI并获取PNP ID。寻找VID（供应商ID）。
我在 Win32_USBControllerDevice 和 Win32_DiskDrive 下看到了我刚刚插入的设备的信息。
您可以通过WMI获取此信息。下面是一个vbs脚本（复制到文本文件，运行.vbs），它使用WMI获取有关 Win32_DiskDrive 对象。 制造商信息可能只是说标准磁盘驱动器，但型号可能有你想要的。
Set Drives = GetObject("winmgmts:{impersonationLevel=impersonate,(Backup)}").ExecQuery("select * from Win32_DiskDrive")
for each drive in drives
Wscript.echo "Drive Information:" & vbnewline & _
"Availability: " & drive.Availability & vbnewline & _

如果 Win32_DiskDrive 对象没有产生您要查找的信息，您还可以查看 Win32_PhysicalMedia WMI对象类。它们具有可能有用的制造商，型号，零件编号和描述属性。
您可以尝试使用WMI
Option Explicit
Dim objWMIService, objItem, colItems, strComputer
' On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" _
& strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery(_
"Select Manufacturer from Win32_DiskDrive")
For Each objItem in colItems
Wscript.Echo "Computer: " & objItem.SystemName & VbCr & _
"Manufacturer: " & objItem.Manufacturer & VbCr & _
"Model: " & objItem.Model
Next
模型比制造商更有帮助。如果您想立即将应用程序锁定到一个制造商和一个（某些）固件版本，请查看FirmwareRevision。
希望它有所帮助。
以防万一其他人在C ++中做到这一点疯狂 - CLI，这里是smink回答的一个端口：
using namespace System;
using namespace System::Management;
void GetUSBDeviceList()
{
try
{
ManagementObjectSearcher^ searcher =
gcnew ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_DiskDrive");
for each (ManagementObject^ queryObj in searcher->Get())
{
Console::WriteLine("DeviceID: {0}", queryObj["DeviceID"]);
Console::WriteLine("PNPDeviceID: {0}", queryObj["PNPDeviceID"]);
Console::WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]);
Console::WriteLine("Model: {0}", queryObj["Model"]);
for each (ManagementObject^ b in queryObj->GetRelated("Win32_DiskPartition"))
{
Console::WriteLine(" Name: {0}", b["Name"]);
for each (ManagementBaseObject^ c in b->GetRelated("Win32_LogicalDisk"))
{
Console::WriteLine(" Name: {0}", c["Name"]); // here it will print drive letter
}
}
// ...
Console::WriteLine("--------------------------------------------");
}
}
catch (ManagementException^ e)
{
Console::WriteLine(e->StackTrace);
}
Console::ReadLine();
}
注意：我必须在我的项目属性中手动添加对 System.Management 库的引用。
