Converting string to timespan - powershell

Question

Im new to powershell and Ive been trying to convert this string to a timespan object:
"2 Days 1 Hour 15 Minutes"
Ive tried several ways to input the format using parseexact but I cant seem to get the right format down.
Ive tried something like this :
[TimeSpan]::ParseExact('2 Days 1 Hour 15 Minutes', 'd \Days h \Hour MM \Minutes', $null)

Answer 1

The TimeSpan parser is very sensitive, you need to escape everything that isn't a format string specifier:
[TimeSpan]::ParseExact('2 Days 1 Hour 15 Minutes', '%d\ \D\a\y\s\ %h\ \H\o\u\r\ %m\ \M\i\n\u\t\e\s', $null)
(I used the percent-sign notation for the specifiers (%d instead of d) to make them stand out in amongst all the \'s, but they're not required)

Answer 2

The string version normally looks like this: '2.01:15:00', so [timespan]'2.01:15' works.

Answer 3

I am glad to see you have an answer. Another way would be to use named captures in a regex.
PS C:\> '2 Days 1 Hour 15 Minutes' -match '^(?<Days>\d+)\D*(?<Hours>\d+)\D*(?<Minutes>\d+)\D*'
True
PS C:\> $matches
Name Value
---- -----
Hours 1
Minutes 15
Days 2
0 2 Days 1 Hour 15 Minutes
PS C:\> $Matches.Days
2
PS C:\> $Matches.Hours
1
PS C:\> $Matches.Minutes
15
PS C:\> $Ts = New-TimeSpan -days $Matches.Days -Hours $Matches.Hours -Minutes $Matches.Minutes
PS C:\> $Ts
