Question

This seems like a really simple thing to do but I cant’t seem to get my ahead around it. I have 10 documents entitled 1.txt to 10.txt. I just want to count the number of lines in each doc and end up with the final summation of the line counts.

This is where I got to.

    for (int i = 1; i < 11; i++)
    {
        int lineCount = File.ReadLines(@i + ".txt").Count();
        lineCount += lineCount; 
        Console.WriteLine("Total IDs: " + lineCount);
    }

UPDATE
My docs have carriage returns at the bottom of them which I do not want to include in the count.

Answer 1

You are reinitializing lineCount every time. Change it like so:

int lineCount = 0;
for (int i = 1; i < 11; i++)
{
    lineCount += File.ReadLines(@i + ".txt").Count();
}
Console.WriteLine("Total IDs: " + lineCount);

This way you don’t reinitialize lineCount every time, and you are simply adding the Count to it for each iteration.
