I have about 1500 files on a share for which I need to collect FileVersionInfo string. So I created a Static method in my Gateway like this:

private static string GetVersionInfo(string filepath)
{
    FileVersionInfo verInfo = FileVersionInfo.GetVersionInfo(filepath);
    return string.Format("{0}.{1}.{2}.{3}", verInfo.ProductMajorPart, verInfo.ProductMinorPart,
                                            verInfo.ProductBuildPart, verInfo.ProductPrivatePart).Trim();
}

And then used FileAndVersion struct in a PLINQ call with DegreeOfParallelism as this is I/O related

resultList = dllFilesRows.AsParallel().WithDegreeOfParallelism(20)
                    .Select(r =>
                    {
                        var symbolPath = r.Filename;
                        return new FilenameAndVersion{Filename=symbolPath, Version=GetVersionInfo(symbolPath)};
                    })
                    .ToArray();

Later I modified the Struct, FileAndVersion as:

private struct FilenameAndVersion 
{
private string _version, _filename;
public string Version { get { return _version; } }
public string Filename { get { return _filename; } }

public void SetVersion()
{
    FileVersionInfo verInfo = FileVersionInfo.GetVersionInfo(this.Filename);
    this._version = string.Format("{0}.{1}.{2}.{3}", verInfo.ProductMajorPart, verInfo.ProductMinorPart,
                                                                                    verInfo.ProductBuildPart, verInfo.ProductPrivatePart).Trim();
}
public FilenameAndVersion(string filename, string version)
{
    this._filename = filename;
    this._version = string.Empty;
    SetVersion();
}
}           

And used it:

resultList = dllFilesRows.AsParallel().WithDegreeOfParallelism(20)
                    .Select(r =>
                    {
                        var symbolPath = r.Filename;
                        return new FilenameAndVersion(symbolPath, String.Empty);
                    })
                    .ToArray();

The question is, is this going to help me in anyway and is a good pattern to use ?
