如何确定USB闪存驱动器制造商？ [英] how to determine USB Flash drive manufacturer?

问题描述

我要我的程序只能使用特定的USB闪存驱动器（从单一的制造商）工作，而忽略其他所有的USB闪存驱动器（从任何其他制造商）。

I need my program to work only with certain USB Flash drives (from a single manufacturer) and ignore all other USB Flash drives (from any other manufacturers).

是可以检查特定的USB卡插入使用​​.NET 2.0的窗口？怎么样？

is it possible to check that specific USB card is inserted on windows using .NET 2.0? how?

如果我觉得通过WMI，可我不知怎么确定哪些驱动器号的USB驱动器上？

if I find it through WMI, can I somehow determine which drive letter the USB drive is on?

推荐答案

编辑：加code打印驱动器盘符

Added code to print drive letter.

检查这个例子为你的作品。它使用WMI。

Check if this example works for you. It uses WMI.

Console.WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]);
...
Console.WriteLine("    Name: {0}", c["Name"]); // here it will print drive letter

The full code sample:

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();
        }
    }
}

我觉得这些属性可以帮助你从别人区别真正的USB驱动器。与几个随身碟测试以检查值相同。请参阅完整的参考 Win32_DiskDrive 这里的属性：
