Question

I have two arrays built while parsing a text file. The first contains the column names, the second contains the values from the current row. I need to iterate over both lists at once to build a map. Right now I have the following:

var currentValues = currentRow.Split(separatorChar); var valueEnumerator = currentValues.GetEnumerator();  foreach (String column in columnList) {     valueEnumerator.MoveNext();     valueMap.Add(column, (String)valueEnumerator.Current); } 

This works just fine, but it doesn’t quite satisfy my sense of elegance, and it gets really hairy if the number of arrays is larger than two (as I have to do occasionally). Does anyone have another, terser idiom?

Answer 1

if there are the same number of column names as there are elements in each row, could you not use a for loop?

var currentValues = currentRow.Split(separatorChar);  for(var i=0;i<columnList.Length;i++){    // use i to index both (or all) arrays and build your map }
