用于ODD(光盘驱动器)的C#PerformanceCounter

问题描述

你好.

我正在创建一个代码，以使用PerformanceCounter检查光盘驱动器(ODD)的性能.

I'm working on create a code to check the performance of Optical Disc Drive (ODD) with PerformanceCounter.

这是测试代码的一部分.

Here is a part of test code.

var cat = new System.Diagnostics.PerformanceCounterCategory("PhysicalDisk");
var instNames = cat.GetInstanceNames();

我将CategoryName用作"PhysicalDisk".和"LogicalDisk"但他们两个都无法检测到ODD.

I've used CategoryName as "PhysicalDisk" and "LogicalDisk" but both of them can't detect ODD.

仅检测硬盘.

是否可以将PerformanceCounter与ODD一起使用?

Is it impossible to use PerformanceCounter with ODD ?

我的错是什么?

推荐答案

感谢您在此处发布帖子，对您的回复表示歉意.

Thank you for posting here and sorry for late reply.

我测试了您的代码，就我而言，我也无法获得ODD.我获得了所有类别的名称，但是无法获得用于获得ODD的合适名称.

I test your code, on my side, I could not get the ODD as well. I get all the category name, however I could not get the suitable name to get the ODD.

您可以尝试另一种方式.

You could try another way. 

  static void Main(string[] args)
        {
            string strDVD;
            try
            {
                string[] Drives = Directory.GetLogicalDrives();
                foreach (var strDrive in Drives)
                {
                    DriveInfo di = new DriveInfo(strDrive.Substring(0, 1).ToUpper());
                    if (di.DriveType == DriveType.CDRom)
                    {
                        strDVD = strDrive.Substring(0, 2);
                        Console.WriteLine(strDVD);
                    }
                }
            }
            catch (Exception e)
            {
                MessageBox.Show("Error", e.Message);
            }
            Console.ReadKey();
       }

我使用代码获取ODD，即DVD RW驱动器(D:).

I use the code to get the ODD, the DVD RW Drive (D:).

我希望这会有所帮助.

最好的问候，
