Read Csv using LINQ

Question

I am having a csv file like this

A, 22, 23, 12
B, 32, 4, 33
C, 34, 3 ,33

I want to print the sum and average of each row and skip the first

Answer 1

using System.IO

// turn file into IEnumerable (streaming works better for larger files)
IEnumerable> GetTypedEnumerator(string FilePath){
  var File = File.OpenText(FilePath);
  while(!File.EndOfStream) 
      yield return new Tuple(
          Int.Parse(File[1]), 
          Int.Parse(File[2], 
          Int.Parse(File[3])
      );
   File.Close();
}

// this lines would return the sum and avg for each line
var tot = GetTypeEnumerator(@"C:\file.csv").Select(l=>l.Item1 + l.Item2 + l.Item3);
var avg = GetTypeEnumerator(@"C:\file.csv").Select(l=> (l.Item1 + l.Item2 + l.Item3) / 3);

The streaming aporoach will let you handle laregr files because you wouldn;t need toload them into memeory first. Don't have VS here, haven't checked the syntax, might not compile as is.
