Question

On an NTFS file system, it is possible to have alternate data streams within a single file. Is it possible to access this information in a fully managed way?

EDIT: additionally, I want to read from the alternate stream in an existing file. How is this achieved (using PInvoke if not possible using managed code only)?

_{This question is similar, but is from early 2009 and the .Net answer uses PInvoke to write to a file, not read from it. Has support for this been added since then (to .Net 4.0?) that can do it without using PInvoke?}

Answer 1

Unfortunately no, there is still no access via a managed .Net Framework API.

Update

Here’s a library\source for an ADS access wrapper:
