An example of mixed abstraction levels in a method

non-slap-code.cs

public class SomeClass
{
	string inputLine;
	List<string> extractedValues = new List<string>();
	
  	// We're assuming that inputFile is a .csv file
  	// containing input values.
	public void DoSomeWork(string inputFile)
	{
		using (var file = new StreamReader(inputFile))
		{
			while ((inputLine = file.ReadLine()) != null)
			{
				// do some work on the line
				var inputData = inputLine.Split(',');
				var desiredValue = inputData[3];
				extractedValues.Add(desiredValue);
			}
		}
	}
