How to iterate over two arrays at once?

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 list

Answer 1

Use IEnumerator for both would be nice

var currentValues = currentRow.Split(separatorChar);
using (IEnumerator valueEnum = currentValues.GetEnumerator(), columnEnum = columnList.GetEnumerator()) {
    while (valueEnum.MoveNext() && columnEnum.MoveNext())
        valueMap.Add(columnEnum.Current, valueEnum.Current);
}

Or create an extension methods

public static IEnumerable Zip(this IEnumerable source, IEnumerable other, Func selector) {
    using (IEnumerator sourceEnum = source.GetEnumerator()) {
        using (IEnumerator otherEnum = other.GetEnumerator()) {
            while (sourceEnum.MoveNext() && columnEnum.MoveNext())
                yield return selector(sourceEnum.Current, otherEnum.Current);
        }
    }
}

Usage

var currentValues = currentRow.Split(separatorChar);
foreach (var valueColumnPair in currentValues.Zip(columnList, (a, b) => new { Value = a, Column = b }) {
    valueMap.Add(valueColumnPair.Column, valueColumnPair.Value);
}
