我需要我的程序只能与某些USB闪存驱动器(来自单个制造商)一起使用，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？

如果通过WMI找到它，是否可以确定USB驱动器在哪个驱动器盘符上？

解决方案

也许#usblib：

我们可以使用非托管Win32 API调用来处理此问题。

编辑：添加代码以打印驱动器号。

检查此示例是否适合我们。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();
        }
    }
}

我认为这些属性应该可以将正版USB驱动器与其他驱动器区分开。用几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：

通过Win32 CM_(设备管理)或者WMI并获取PNP ID。查找VID(供应商ID)。

我在" Win32_USBControllerDevice"和" Win32_DiskDrive"下看到了刚刚插入的设备的信息。

我们也许可以通过WMI获得此信息。下面是一个vbs脚本(复制到运行.vbs的文本文件)，该脚本使用WMI获取有关Win32_DiskDrive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"可能符合要求。

嗨，尝试使用WMI进行此操作

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

模型可能比制造商更有帮助。如果要立即将应用程序锁定为仅一个制造商和一个(某些)固件修订版，则可以查看FirmwareRevision。

希望能帮助到你。

如果" Win32_DiskDrive"对象没有产生我们要查找的信息，则我们还可以查看WMI对象的Win32_PhysicalMedia类。它们具有制造商，型号，零件号和描述属性，这些属性可能被证明是有用的。
