如何找出正在使用哪个进程的文件

Question

我在尝试使用.mkv文件（vlc.exe，mpc-hc.exe等）进程的名称

我已经设法发现它是否在使用中，但我想知道至关重要的进程正在使用该文件。

我试过了这个帖子How do I find out which process is locking a file using .NET?的建议，但只是插入文件的路径并运行它似乎没有工作，它没有显示任何进程（我可以运行代码没有错误）。

public static bool IsFileinUse(FileInfo file) 
{ 
    FileStream stream = null; 

    try 
    { 
     stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None); 
    } 
    catch (IOException) 
    { 
     //the file is unavailable because it is: 
     //still being written to 
     //or being processed by another thread 
     //or does not exist (has already been processed) 
     return true; 
    } 
    finally 
    { 
     if (stream != null) 
      stream.Close(); 
    } 
    return false; 
}

试试这个：

string fileName = @"c:\yourFile.doc";//Path to locked file 

Process tool = new Process(); 
tool.StartInfo.FileName = "handle.exe"; 
tool.StartInfo.Arguments = fileName+" /accepteula"; 
tool.StartInfo.UseShellExecute = false; 
tool.StartInfo.RedirectStandardOutput = true; 
tool.Start();   
tool.WaitForExit(); 
string outputTool = tool.StandardOutput.ReadToEnd(); 

string matchPattern = @"(?<=\s+pid:\s+)\b(\d+)\b(?=\s+)"; 
foreach(Match match in Regex.Matches(outputTool, matchPattern)) 
{ 
    Process.GetProcessById(int.Parse(match.Value)).Kill(); //kill the process if you want 
}
