Question

I currently have two arrays one the stores a file name and another that stores the file size. I need to show both the maximum file size and its name. I can get it to show the largest file by using this code.

        long[] fileSize;
        string[] fileName;
        fileSize = new long[fileCount];
        fileName = new string[fileCount];
        for (int index = 0; index < files.Length; index++)
        {
            fileSize[index] = files[index].Length;
            fileName[index] = files[index].Name;
        }
        long largestFile = fileSize.Max();
        string latestFileName = fileName[fileSize.Max()];
        Console.WriteLine("Total size of all files: {0}", totalSize);
        Console.WriteLine("Largest file: {1}, {0}", largestFile, latestFileName );

I have tried using google but it just tells me how to work out the maximum or minimum.

There’s no need for separate arrays for the name and size, just loop over your files array, and keep track of the current max file size and it’s name in separate variables. Something like this:

int max = 0;
string name = string.Empty;

for (int index = 0; index < files.Length; index++)
{
    int size = files[index].Length;
    //check if this file is the biggest we've seen so far
    if (size > max)
    {
        max = size; //store the size
        name = files[index].Name; //store the name
    }
}

//here, "name" will be the largest file name, and "max" will be the largest file size.
