Problems parsing CSV file row into Object Graph

Question

here's what my csv file looks like:

1,couchName1,“green”,“suede”
2,couchName2,“blue”,“suede”
3,couchName3,fail,“sued”
...etc.

I need to read this csv and convert each row into a couch object graph. So here is what I tried:

    public static IEnumerable<string[]> ReadCsvFile(string filePath)
    {
        IEnumerable<string[]> file = File.ReadLines(filePath).Select(a => a.Split(';'));
        return file;
    }


public static List<Couch> GetCouches(string csvFilePath)
{
    IEnumerable<string[]> fileRows = FileUtilities.ReadCsvFile(csvFilePath);

    if (fileRows == null) return new List<Couch>(); 
    int couchId;

    List<Couch> couches = fileRows.Select(row => new Couch
     {  
        CouchId = int.TryParse(row[0],  out couchId) ? couchId : 0,
        Name= row[1],
        Color= row[2],
        Fabric= row[3]
       }).ToList();

    return couches;
}

I get the error {"Index was outside the bounds of the array."} on the line with the LINQ select statement where I'm trying to parse them into my Couch instances and into a generic list that I want to return them by.

SOLUTION:

Here's how I got it working, solved it myself:

public static List<Couch> GetCouches(string csvFilePath)
{
    IEnumerable<string[]> fileRows = FileUtilities.ReadCsvFile(csvFilePath);
    List<Couch> couches = new List<Couch>(); // ADDED THIS

    if (fileRows == null) return new List<Couch>(); 
    int couchId;

    // NEW LOGIC, SPLIT OUT EACH ROW'S COLUMNS AND THEN MAKE THE OBJECT GRAPH
    foreach(string[] row in fileRows)
    {
        string[] rowColumnValues = row[0].Split(',').ToArray();

        couches.Add(new Couch
                            {
                              CouchId = int.TryParse(rowColumnValues[0],  out couchId) ? couchId : 0,
                              Name= rowColumnValues[1],
                              Color= rowColumnValues[2],
                              Fabric= rowColumnValues[3]
    }

    return couches;
}

Answer 1

我能想到的唯一原因是fileRows中的某些行可能没有预期的四个元素。

Answer 2

figured it out. I needed to split the rows into columns.
