I have two FileInfo[] Array's and i want compare the Files with identical Names about their File Size and Last Modified Date. But how can i select a File out of a FileInfo[] with a specific Name?

My Code doesnt work, because i cant use FileInfo.Select to get a new FileInfo out. Any clues?

        foreach (FileInfo origFile in fiArrOri6)

        {

            FileInfo destFile = fiArrNew6.Select(file => file.Name == origFile.Name);

            if (origFile.Length != destFile.Length || origFile.LastWriteTime != destFile.LastWriteTime)

            {

                //do sth.

            }

        }

Thanks for any help :)

Any other charming solution for this Problem would be great. btw. #2 : does someone has good learning material for FileInfo?

    Hi Jayprakash,

    You could use the FirstOrDefault that takes a filter

    FileInfo destFile = fiArrNew6.FirstOrDefault(file => file.Name == origFile.Name);

    Or, if you don't want the default, you can use the equivalent First that takes a filter

    FileInfo destFile = fiArrNew6.First(file => file.Name == origFile.Name);
