Update DLL RC info from powershell - powershell

Question

I'm trying to update/add some RC information in DLL directly from the Powershell.
I have found how I can get it but I didn't found how set some field like SpecialBuild or PrivateBuild.
PS C:\> (gi .\mydll.dll).VersionInfo | fl
OriginalFilename : mydll.dll
FileDescription : mydll.dll
...............................
PrivateBuild : 32572
SpecialBuild : NOT_HOTFIX
FileVersionRaw : 17.3.0.12013
ProductVersionRaw : 17.3.0.12013
PS C:\> (gi .\mydll.dll).VersionInfo | gm
TypeName : System.Diagnostics.FileVersionInfo
Name MemberType Definition
---- ---------- ----------
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
Comments Property string Comments {get;}
.................................................
PrivateBuild Property string PrivateBuild {get;}
ProductBuildPart Property int ProductBuildPart {get;}
ProductMajorPart Property int ProductMajorPart {get;}
ProductMinorPart Property int ProductMinorPart {get;}
ProductName Property string ProductName {get;}
ProductPrivatePart Property int ProductPrivatePart {get;}
ProductVersion Property string ProductVersion {get;}
SpecialBuild Property string SpecialBuild {get;}
FileVersionRaw ScriptProperty System.Object FileVersionRaw {get=New-Object System.Version -ArgumentList #(...
ProductVersionRaw ScriptProperty System.Object ProductVersionRaw {get=New-Object System.Version -ArgumentList #(...
As you can see, properties are get only here.
So do you know how I can update theses fields ?
Thanks in advance for your help ;)

Answer 1

Update fields possible with a tool like Resource Hacker, or verpatch, but it's not recommended. If the dll is yours, it's much easier to update it before compilation.
One of the downsides of patching compiled dll is that if it's signed, the signature will no longer be valid. Also, sometimes patching may result in a corrupted dll.
Is there any particular reason why you want to change it after compilation?
