c# - How to avoid System.IO.PathTooLongException?

Question

We constantly run into this problem...

Example:

if I have a file that I want to copy it into an another directory or UNC share and if the length of the path exceeds 248 (if I am not mistaken), then it throws PathTooLongException. Is there any workaround to this problem?

PS: Is there any registry setting to set this path to a longer char set?

Answer 1

As described in Jeremy Kuhne's blog, .NET Framework 4.6.2 removes the MAX_PATH limitation where possible, without breaking backwards compatibility.
