I want to store version in database table and don’t want to use varchar(max)

  • 0

I want to store version in database table and don’t want to use varchar(max) for that. I want something fixed varchar(xxx)

Could you please tell, what’s the maximum possible length of FileVersionInfo.FileVersion on Windows Platforms?

Actually figured out how to get proper version:

var ver = FileVersionInfo.GetVersionInfo("D:\\oraociei11.dll").FileVersion;

This returns for Oracle lib:

oranipc11.dll - 11.2.0.2.0 Production

To get version of file in proper way:

var versionInfo = FileVersionInfo.GetVersionInfo("D:\\oraociei11.dll");
var properVersion = string.Format("{0}.{1}.{2}.{3}", versionInfo.FileMajorPart, versionInfo.FileMinorPart, versionInfo.FileBuildPart, versionInfo.FilePrivatePart);

Thanks guys for participating!

    No, FileVersion is a string and can contain anything. The Visual Studio resource editor allows entering a string of up to 300 characters. That is however not enforced by the resource compiler, longer strings can be entered by editing the .rc file by hand.

    What you’ll want to do is synthesize the version string yourself, like this:

            var info = System.Diagnostics.FileVersionInfo.GetVersionInfo(path);
        var version = string.Format("{0}.{1}.{2}.{3}", 
            info.FileMajorPart, info.FileMinorPart, info.FileBuildPart, info.FilePrivatePart);

    Which then ensures this string can never be larger than 23 characters.
