我需要我的程序仅适用于某些 USB 闪存驱动器(来自单个制造商)并忽略所有其他 USB 闪存驱动器(来自任何其他制造商)。
是否可以使用 .NET 2.0 检查是否在 Windows 上插入了特定的 USB 卡?如何?
如果我通过 WMI 找到它,我能以某种方式确定 USB 驱动器在哪个驱动器号上吗?
编辑:添加代码以打印驱动器号。
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();
}
}
}
我认为这些属性应该可以帮助您将真正的 USB 驱动器与其他驱动器区分开来。使用多个笔式驱动器进行测试以检查值是否相同。在此处查看Win32_DiskDrive属性的完整参考:

检查这篇文章是否对您也有帮助:
您可以使用非托管 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。查找 VID(供应商 ID)。
Win32_USBControllerDevice
我在和下看到了我刚刚插入的设备的信息Win32_DiskDrive
。
您可以通过 WMI 获取此信息。下面是一个 vbs 脚本(复制到带有 .vbs 的文本文件以运行),它使用 WMI 来获取有关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,但型号可能包含您要查找的内容。
Set Drives = GetObject("winmgmts:{impersonationLevel=impersonate,(Backup)}").ExecQuery("select * from Win32_DiskDrive")

如果Win32_DiskDrive
对象没有产生您正在寻找的信息,您还可以查看 WMI 对象的Win32_PhysicalMedia类。它们具有可能被证明有用的制造商、型号、零件编号和描述属性。
嗨,在使用 WMI 时试试这个
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。如果您现在只想将您的应用程序锁定到一个制造商和一个(某些)固件版本,您可以查看 FirmwareRevision。
希望能帮助到你。
以防万一其他人足够疯狂地在 C++-CLI 中执行此操作,这里是 smink 答案的一个端口:
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();
}
System.Management
注意:我必须在我的项目属性中手动添加对库的引用。
