I am trying to setup a PowerShell script that would replace a matching string from my GlobalAssemblyInfo.cs file. I am basically looking to update the Version number via powershell so I can do that in a post build automatically. Anyways, the input string from the cs file is this:
//------------------------------------------------------------------------------// <auto-generated>// This code was generated by a tool.// Runtime Version:4.0.30319.42000//// Changes to this file may cause incorrect behavior and will be lost if// the code is regenerated.// </auto-generated>//------------------------------------------------------------------------------using System.Runtime.InteropServices;[assembly: System.Reflection.AssemblyVersion("1.1.31.0")][assembly: System.Reflection.AssemblyCompany("Name")][assembly: System.Reflection.AssemblyProduct("Name")][assembly: System.Reflection.AssemblyCopyright("Name")]// Setting ComVisible to false makes the types in this assembly not visible// to COM components. If you need to access a type in this assembly from// COM, set the ComVisible attribute to true on that type.[assembly: ComVisible(false)]My PowerShell script that I am attempting is this:
$file = "C:\users\konrad\desktop\GlobalAssemblyInfo.cs"$pattern = '^\[assembly: System\.Reflection\.AssemblyVersion\("(.*)"\)\]'$version = '2.0.0.0_delta'(Get-Content $file).replace($pattern, "$1 $version") | Set-Content $fileAgain, the idea is to get the version number that is between the ("") and replace it with a string called $version. I am not getting any errors with the above code. It simply doesn't work. Any ideas would be appreciated.
Cheers!
EDIT:
@Abraham Zinala suggested using -replace instead. I tried that.
(Get-Content $file) -replace $pattern, "$1$version" | Set-Content $file
This replaces this:
[assembly: System.Reflection.AssemblyVersion("1.1.31.0")]
into this:
2.0.0.0_delta
What I want is this:
[assembly: System.Reflection.AssemblyVersion("2.0.0.0_delta")]

Abraham's helpful comment already pointed out the key issue, .Replace(..) string method is not regex compatible, you can use the -replace operator for regex replacements. As for your desired output, you could use the following pattern:
$pattern = '(?m)(^\[assembly: System\.Reflection\.AssemblyVersion\(")[\d.]+'$version = '2.0.0.0_delta'(Get-Content $file -Raw) -replace $pattern, "`${1}$version" | Set-Content ...See https://regex101.com/r/VLoUN2/1 for explanation.
You might want to change [\d.]+ for [\w\d.]+ in case the version you're looking to replace could also contain word characters and underscores.
