获取当前进程名称与文件扩展名在c＃ [英] get current process name with file extension in c#

问题描述

GetAllProccess函数返回Windows中的所有运行进程。我想获取当前进程名，其扩展名为。avi，.mkv，.mpg，.mp4，.wmv

eg如果我在Windows媒体播放器中播放任何视频文件，它返回（wmplayer.exe）或如果我在KM PLAYER中播放任何视频文件，它返回（kmplayer.exe）

感谢
这里是我的代码此代码工作速度很慢
参考 http://vmccontroller.codeplex.com / SourceControl / changeset / view / 47386＃195318

GetAllProccess Function Return All Runing Proccesses In Windows. I want to get current proccess name which extension is ".avi", ".mkv", ".mpg", ".mp4", ".wmv"
e.g. if I play any video file in windows media player it return (wmplayer.exe) or if I play any video file in KM PLAYER it returns(kmplayer.exe)
Thanks here is my code this code working very slow reference http://vmccontroller.codeplex.com/SourceControl/changeset/view/47386#195318

string filename;
Process [] procs = Process.GetProcesses（）;
foreach（procs中的进程prc）
{

string filename; Process[] procs = Process.GetProcesses() ; foreach (Process prc in procs) {

            if (procs.Length > 0)
            {
                int id = prc.Id;
                IEnumerator<FileSystemInfo> fie = DetectOpenFiles.GetOpenFilesEnumerator(id);

                while (fie.MoveNext())
                {
                    if (fie.Current.Extension.ToLower(CultureInfo.InvariantCulture) == ".mp3")
                    {
                        filename = fie.Current.FullName;
                        break; // TODO: might not be correct. Was : Exit While
                    }
                }
            }
        }

推荐答案

您可以先看看 Handle By Mark Russinovich 。

您可以使用以下语法将结果放入一个文本文件：

You could use the following syntax to put the results into a text file:

handle.exe > log.txt

之后，您可以使用 PowerShell 使用这些数据文件提取有关进程的信息：

Afterwards, you may use PowerShell to extract the information about the processes using those data files:

Get-Content log.txt | 
    where{$_.readcount -gt 6} | 
    foreach{
        if($_.Substring(0,1) -ne " " -and $_.Substring(0,1) -ne "-")
        {$process = $_.ToString()}
        elseif($_.ToLower() -like "*.avi" `
            -or $_.ToLower() -like "*.mkv" `
            -or $_.ToLower() -like "*.mpg" `
            -or $_.ToLower() -like "*.mp4" `
            -or $_.ToLower() -like "*.wmv" `
            )
        {$process.ToString()}
    }

这是从C＃（你需要以管理员身份运行应用程序）相同的方法：

Here's the same approach from C# (you need to run the application as Administrator):

class Program
{
    static void Main(string[] args)
    {
        var processes = GetProcesses();

        // enumerate the processes
        foreach (Tuple<int,string> mediaFile in processes.Distinct())
        {
            var process = Process.GetProcesses().Where(i => i.Id == mediaFile.Item1).FirstOrDefault();
            Console.WriteLine("{0} ({1}) uses {2}", process.ProcessName, process.Id, mediaFile.Item2);
        }
        Console.ReadLine();
    }

    private static List<Tuple<int,string>> GetProcesses()
    {
        string line = "";
        int counter = 0;
        string currentProcess = "";
        List<Tuple<int, string>> mediaFiles = new List<Tuple<int, string>>();

        Process compiler = new Process();
        compiler.StartInfo.FileName = @"c:\YourPath\Handle.exe";
        compiler.StartInfo.CreateNoWindow = true;
        compiler.StartInfo.UseShellExecute = false;
        compiler.StartInfo.RedirectStandardOutput = true;
        compiler.Start();

        while ((line = compiler.StandardOutput.ReadLine()) != null)
        {
            // skipping applicaion info
            if (++counter > 6)
            {
                if (!" -".Contains(char.Parse(line.Substring(0, 1))))
                {
                    currentProcess = line;
                }
                else if ((new[] { ".avi", ".mkv", ".mpg", ".mp4", ".wmv" })
                    .Contains(line.ToLower().Substring(line.Length - 4)))
                {
                    int pos = currentProcess.IndexOf("pid:") + 5;
                    string pid = currentProcess.Substring(pos, currentProcess.IndexOf(" ", pos) - pos);
                    mediaFiles.Add(new Tuple<int, string>(Int32.Parse(pid),line.Substring(21)));
                }
            }
        }
        compiler.WaitForExit();

        return mediaFiles;
    }
}
