Searching for backslash in a string with Powershell

问题

I need to search for the amount of backslashes in a string to determine some file path parameters. I have not worked out a way to seach for a backslash without Powershell thinking it is an escapee character.

([regex]::Matches($FilePath, "\" )).count 

Or

$a -match "\"

These both come up with an error "Illegal \ at end of pattern"

Thanks!

You can escape a backslash with a backslash:

[Regex]::Matches($FilePath, "\\").Count
