What you're after is called the Package Code.

Here's an example to retrieve using VBscript (unfortunately I'm not familiar with .NET):

Dim installer, database

Set installer = CreateObject("WindowsInstaller.Installer")
Set database = installer.OpenDatabase ("my.msi", 0)

Dim sumInfo  : Set sumInfo = installer.SummaryInformation("my.msi", 0)
sPackageCode =  sumInfo.Property(9) ' PID_REVNUMBER = 9, contains the package code.

WScript.Echo sPackageCode
