How Can I Programmatically Determine Open File Handles and Their Associated Filenames for a Specific Process in C#?

Programmatically Accessing Open File Handles and Filenames in C#

Determining which files a specific process has open, including their filenames, is a challenging task in C#. This requires interacting directly with the Windows API, particularly if you need the same level of detail as tools like Process Explorer.

Interoperability Challenges

While much of this can be done via interop, getting the filenames requires accessing the kernel's memory space. Process Explorer achieves this with an embedded driver, but integrating this driver into a C# application and handling both 32-bit and 64-bit systems presents significant difficulties.

CodeProject Reference and Complexity

A CodeProject example demonstrates the complexity involved. The code utilizes interop functions and requires careful handling of 32-bit and 64-bit architectures, making it a substantial undertaking.

Significant Complexity and Limitations

It's crucial to understand the inherent complexity. Using C# and interop to programmatically retrieve open file handles and their associated filenames is not straightforward. The lack of a simple, readily available solution underscores the difficulty of this task.
