Solution 1

You can make use of the System.Reflection library to get the information about any assembly. The property you're looking for is Version property of the AssemblyName class.

For more details check out this MSDN article.

Have a good day.

Solution 2

If all you are after is information about the file version; use the FileVersionInfo[^] class. It does exactly what the name suggests. For instance, if you want the file version, you would do this:

C#

FileVersionInfo versionInfo = FileVersionInfo.GetVersionInfo(filePath);
string productVersion = versionInfo.FileVersion;
