How do I get the list of open file handles by process id in C#?

I'm interested in digging down and getting the file names as well.

Looking for the programmatic equivalent of what process explorer does.

Most likely this will require interop.

Considering adding a bounty on this, the implementation is nasty complicated.


Ouch this is going to be hard to do from managed code.

There is a sample on codeproject

Most of the stuff can be done in interop, but you need a driver to get the filename cause it lives in the kernel's address space. Process Explorer embeds the driver in its resources. Getting this all hooked up from C# and supporting 64bit as well as 32, is going to be a major headache.

How do I get the list of open file handles by process in C, It looks like a problem. It is solvable, but probably not in a compatible way. And you will need to use P/Invoke  How do I get the list of open file handles by process id in C#? I'm interested in digging down and getting the file names as well.

You can also run the command line app, Handle, by Mark Rusinovich, and parse the output.

Network Security Hacks, Running handle without any command-line arguments will list all open file will list the processes that are currently accessing it, by typing this: C:\x handle  You can get a List collection of the file paths in a directory. First get an array from GetFiles. Then you can convert the array to a List with the ToList extension method. Tip: Include the System.Linq namespace at the top first—it is included by default in new files.


Have a look at this file : http://vmccontroller.codeplex.com/SourceControl/changeset/view/47386#195318

And use:

DetectOpenFiles.GetOpenFilesEnumerator(processID);

Demo:

using System;
using System.Diagnostics;

namespace OpenFiles
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var openFiles = VmcController.Services.DetectOpenFiles.GetOpenFilesEnumerator(Process.GetCurrentProcess().Id))
            {
                while (openFiles.MoveNext())
                {
                    Console.WriteLine(openFiles.Current);
                }
            }
            Console.WriteLine();
            Console.ReadKey();
        }
    }
}

It has dependency over assembly System.EnterpriseServices

Linux System Programming: Talking Directly to the Kernel and C Library, The kernel maintains a per-process list of open files, called the file table. This table is indexed via nonnega- tive integers known as file descriptors (often  View open files and the corresponding process names. After restarting Windows, from an admin Command Prompt window, type: openfiles. This lists the File/Handle ID, Process Name and the list of files opened locally or opened remotely via local share points, in a table format. To view the output in List or CSV formats, use the /query parameter.


You can P/INVOKE into the NtQuerySystemInformation function to query for all handles and then go from there. This Google groups discussion has details.

UNIX Systems Programming: Communication, Concurrency, and Threads, Files are designated within C programs either by file pointers or by file descriptors. The UNIX I/O functions (open, read, write, close and ioctl) use file descriptors. The symbolic names for the file pointers that represent standard input, standard output model for handling file descriptors and file pointers within a process.

Take a look at wj32's Process Hacker version 1, which can do what you asked, and more.

How to list the open file descriptors (and the files they refer to) in my , Yes, this will list all open file descriptors: $ ls -la /proc/$$/fd total 0 dr-x------ 2 isaac isaac 0 Dec 28 00:56 . dr-xr-xr-x 9 isaac isaac 0 Dec 28 00:56 .. lrwx------ 1​  Long ago it was impossible to reliably get the list of processes locking a file because Windows simply did not track that information. To support the Restart Manager API, that information is now tracked. I put together code that takes the path of a file and returns a List<Process> of all processes that are locking that file.

C# OpenFileDialog control allows us to browse and select files on a computer in an application. A typical Open File Dialog looks like Figure 1 where you can see Windows Explorer like features to navigate through folders and select a file.

You can also specify a particular process by process name or process ID (PID) or pass a process object through the pipeline to this cmdlet. By default, this cmdlet returns a process object that has detailed information about the process and supports
