Code Snippet using System; using System.Management; // Search the processes which have a certain file open class App { public static void Main() { WhoHasThisFileOpen(@c:\windows\system32\wsock32.dll); } static void WhoHasThisFileOpen(string objectQry){ SelectQuery query = new SelectQuery(select name from cim_datafile where name =' + objectQry +' ); using(ManagementObjectSearcher searcher = new ManagementObjectSearcher(query)) { foreach (ManagementObject mo in searcher.Get()) { Console.WriteLine(File Name: {0} 
Is currently opened by: mo.Properties[Name].Value); // Get processes having this File open foreach (ManagementBaseObject b in mo.GetRelated(Win32_Process)) { ShowProcessProperties(b.ToString()); b.Dispose(); } } } } static void ShowProcessProperties(string objectClass) { using(ManagementObject process = new ManagementObject (objectClass)) { process.Get(); PropertyDataCollection processProperties = process.Properties; Console.WriteLine(ProcessID: {06} 	CommandLine: {1}  processProperties[ProcessID].Value processProperties[CommandLine].Value); } } }
