Getting Files with batch by batch From Hard Disk

Question

hi,
I have lakhs of xml files in my hard disk, and there is no specific pattern in the file name, I have to load the xml files in iteration by iteration. For each iteration i have to load 200 files, is there is any way to do with DirectoryInfo.GetFiles() ?
with regards
Ahamed.

Hi,
This not possible with DirectoryInfo.GetFiles(), you can do your own custom solution by filling the
whole file name into a string array and then loop over by using ArraySegment, see below:
int count = 10;//hop size
            int offset =0;
            int segmentsize = 10;
            bool stop = false;
            string[] filePaths = Directory.GetFiles(@"yourpath", "*.xml", SearchOption.TopDirectoryOnly);
            do
                if ((offset + count) > filePaths.Length)//Validate that you not running over the array index
                    count = filePaths.Length - offset;
                    stop = true;
                var segment = new ArraySegment<string>(filePaths, offset, count);
                for (int i = segment.Offset; i <= segment.Count + segment.Offset - 1; i++)
                    Console.WriteLine(segment.Array[i]);//Do your work here over the files
                offset = offset + segmentsize;//increment the offset to read the next segment size,
            } while (stop == false);
