Question

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？

Answer 1

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：

Answer 2

您可以使用非托管的Win32 API调用来处理此问题。

Answer 3

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下找到了我刚刚插入的设备的信息。

Answer 4

您可以通过WMI获取此信息。下面是一个vbs脚本（复制到运行.vbs的文本文件），它使用WMI获取有关Win32_DiskDrive个对象的一些信息。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 & _
       "BytesPerSector: " & drive.BytesPerSector & vbnewline & _

Answer 5

如果Win32_DiskDrive个对象没有产生您要查找的信息，您还可以查看Win32_PhysicalMedia类WMI对象。它们具有可能有用的制造商，型号，零件编号和描述属性。

Answer 6

也许#usblib：

Answer 7

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。
