使用C#如何查看哪些文件被哪些进程占用了

string fileName = @"C:\Target\Plugins\print\NLog.dll";

//要检查被那个进程占用的文件

Process tool = new Process();

tool.StartInfo.FileName = @"C:\soft\Handle\handle64.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();

    var pro = Process.GetProcessById(int.Parse(match.Value));

}
