RSCG–AMS – About My software –Reading csproj– part 6

Now it is time to put some more data – like authors and version. I have read a lot ( and tried a lot) about  CompilerVisibleProperty and  CompilerVisibleItemMetadata ( see https://github.com/dotnet/roslyn/blob/main/docs/features/source-generators.cookbook.md  ) . However,I was unable to get the data ( Authors and Version) from there .

So this is what I was get,to read the csproj near the program:

private ItemsFromCSPROJ TryGetPropertiesFromCSPROJ(GeneratorExecutionContext context)
{
    var ret= new ItemsFromCSPROJ();
    try
    {
        var dirFolder = ((dynamic)(context.Compilation)).Options?.SourceReferenceResolver?.BaseDirectory;
        if (string.IsNullOrWhiteSpace(dirFolder))
            return ret;

        var file = Directory.GetFiles(dirFolder,"*.csproj");
        if (file.Length != 1)
            throw new ArgumentException($"find files at {dirFolder} :{file.Length} ");

        var xmldoc = new XmlDocument();
        xmldoc.Load(file[0]);
        XmlNode node;
        node = xmldoc.SelectSingleNode("//Authors");
        ret.Authors = node?.InnerText;
        node = xmldoc.SelectSingleNode("//Version");
        ret.Version = node?.InnerText;
        return ret;
    }
    catch(Exception )
    {
        //maybe log warning? 
        return ret;
    }

}

Next time I will show how it looks
