I\'m trying to use a powershell regex to pull version data from the AssemblyInfo.cs file. The regex below is my best attempt, however it only pulls the string [assembly:
For the generic solution of data between double quotes, the other answers are great. If I were parsing AssemblyInfo.cs for the version string however, I would be more explicit.
$versionString = [regex]::match($s, 'AssemblyVersion.*([0-9].[0-9].[0-9].[0-9])').Groups[1].Value
$version = [version]$versionString
$versionString
1.0.0.0
$version
Major Minor Build Revision
----- ----- ----- --------
1 0 0 0
Update/Edit:
Related to parsing the version (again, if this is not a generic question about parsing text between double quotes) is that I would not actually have a version in the format of M.m.b.r
in my file because I have always found that Major.minor are enough, and by using a format like 1.2.*
gives you some extra information without any effort.
See Compile date and time and Can I generate the compile date in my C# code to determine the expiry for a demo version?.
When using a * for the third and fourth part of the assembly version, then these two parts are set automatically at compile time to the following values:
third part is the number of days since 2000-01-01
fourth part is the number of seconds since midnight divided by two (although some MSDN pages say it is a random number)
Something to think about I guess in the larger picture of versions, requiring 1.2.*, allowing 1.2, or 1.2.3, or only accepting 1.2.3.4, etc.
