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));

}
