To detect that a file is occupied by that process, you need to use the Microsoft-provided tool Handle.exe, which has Microsoft-provided downloads

We can call Handle.exe in C # to detect which process is consuming the file

stringFileName =@"C:\aaa.doc";//to check the files that were occupied by that processProcess Tool=NewProcess (); tool. Startinfo.filename="Handle.exe"; tool. Startinfo.arguments= filename+"/accepteula"; tool. Startinfo.useshellexecute=false; tool. Startinfo.redirectstandardoutput=true; tool.           Start (); Tool. WaitForExit ();stringOutputtool =tool. Standardoutput.readtoend ();stringMatchpattern =@"(? <=\s+pid:\s+) \b (\d+) \b (? =\s+)";foreach(Match matchinchregex.matches (Outputtool, Matchpattern)) {Process.getprocessbyid (int. Parse (match. Value)). Kill ();}
