如何确定USB闪存盘制造商？

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？怎么样？

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？

编辑:添加了打印驱动器号的代码.

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正版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:
