इस प्रश्न का मूल उत्तर था जो अब 7 साल से अधिक पुराना है। यह कोड https://gist.github.com/ieb/2290426 पर संरक्षित है यदि आपको किसी कारण के लिए Windows XP का उपयोग करने की आवश्यकता है तो यह पुराना संस्करण आपके लिए काम कर सकता है

फ़ाइल लॉक की जांच करने के लिए एक बेहतर जवाब क्या है ?

मैंने एरिक जम्मू के उत्तर का दोहराया है (पुराने कूट से मेल खाने के लिए जोड़ा गया बयानों और कक्षा और विधि नामों का उपयोग करने के साथ) कृपया ध्यान दें कि इस उत्तर की टिप्पणियां समय-समय पर हो सकती हैं।

जैसे प्रयोग करें:

बहुत सारे विवरण को छोड़कर:

अनलकर की कोशिश करो यदि आप दूसरी प्रक्रिया द्वारा लॉक की गई फ़ाइल को आज़माते हैं और हटाते हैं, तो वह प्रक्रिया (एस) की सूची होगी, जिसकी फाइल लॉक है। तब आप फ़ाइल को उन प्रक्रियाओं को बंद करके अनलॉक कर सकते हैं

मुझे विश्वास है कि आपको पूरी तरह से सवाल का उत्तर देने के लिए कर्नेल मोड में चल रहे कोड की आवश्यकता है (लेकिन मैंने पुनरारंभ प्रबंधक एपीआई नहीं देखा है)।

आप सभी प्रक्रियाओं और उनके मॉड्यूल की गणना कर सकते हैं – इसलिए यदि आप जो फ़ाइल ढूंढ रहे हैं वह एक मॉड्यूल (डीएलएल, एक्सई, ओसीएक्स …) है, तो आप जाने के लिए अच्छा है लेकिन अगर यह उदाहरण के लिए एक पाठ फ़ाइल है, तो आपको कर्नेल संभाल तालिका को देखना होगा जो आप उपयोगकर्ता मोड से नहीं देख सकते हैं। ऐसा करने के लिए Handle.exe में एक कर्नेल ड्राइवर होता है।

आपको बिल्कुल कर्नेल मोड में चलाने की आवश्यकता नहीं है (!!!)
यह विंडोज 95 (!) (सी, गूगल समूह, Win32 में) के बाद से एक Win32 अकसर किये गए सवाल है: हेलमेट टेबल पढ़ो, बेशक यूजर मोड से, और पीआईडी ​​को फ़ाइल संभाल से …

मैं समाधान में GetProcessesLockingFile () विधि को दोबारा लिखता हूं कोड काम नहीं कर रहा था उदाहरण के लिए, आपके पास फ़ोल्डर "C:\folder1\folder2" और फ़ोल्डर 2 (प्रोसेस 1) में एक प्रक्रिया है। यदि प्रक्रिया चल रही थी, तो GetProcessesLockingFile () मुझे "C:\folder1\folder2" लौट रहा था इसलिए if (files.Contains(filePath)) => if ("C:\folder1\folder2".contains("C:\folder1\folder2\process1")) कभी भी सच नहीं था।

तो यह मेरा समाधान है:

 public static List<Process> GetProcessesLockingFile(FileInfo file) { var procs = new List<Process>(); var processListSnapshot = Process.GetProcesses(); foreach (var process in processListSnapshot) { if (process.Id <= 4) { continue; } // system processes List<string> paths = GetFilesLockedBy(process); foreach (string path in paths) { string pathDirectory = path; if (!pathDirectory.EndsWith(Constants.DOUBLE_BACKSLASH)) { pathDirectory = pathDirectory + Constants.DOUBLE_BACKSLASH; } string lastFolderName = Path.GetFileName(Path.GetDirectoryName(pathDirectory)); if (file.FullName.Contains(lastFolderName)) { procs.Add(process); } } } return procs; } 

Or with a string parameter:

 public static List<Process> GetProcessesLockingFile(string filePath) { var procs = new List<Process>(); var processListSnapshot = Process.GetProcesses(); foreach (var process in processListSnapshot) { if (process.Id <= 4) { continue; } // system processes List<string> paths = GetFilesLockedBy(process); foreach (string path in paths) { string pathDirectory = path; if (!pathDirectory.EndsWith(Constants.DOUBLE_BACKSLASH)) { pathDirectory = pathDirectory + Constants.DOUBLE_BACKSLASH; } string lastFolderName = Path.GetFileName(Path.GetDirectoryName(pathDirectory)); if (filePath.Contains(lastFolderName)) { procs.Add(process); } } } return procs; }
