Question

I have a list of string arrays:

List<string[]> parsedRaw = new List<string[]>();

This list contains lines read in from a CSV, where parsedRaw[3][5] would be the fifth item read off the third line of the CSV.

I know that I can find the number of rows in the list with:

parsedRaw.Count

But, given a row, how can I find the number of elements in that row? I’m trying to implement a test before entering a loop to read from the list, in order to avoid an “Index was outside the bounds of the array” error, where the loop is:

for (k = 0; k < nBytes; k++)
{
    TheseBytes[k] = (byte)parsedRaw[i][StartInt + k];
}

I’m encountering the error on a row in the CSV that has fewer elements than the others. Before entering this loop, I need to check whether parsedRaw[i] has at least “StartInt + nBytes” elements.

Thanks for any suggestions!

A row is just a string array string[], so you can find its size using the Length property of the array.

foreach (string[] row in parsedRaw) {
    for (int i = 0 ; i != row.Length ; i++) {
        // do something with row[i]
    }
}
