Parsing a CSV with comma in data [duplicate]

Answer 1

You can't just split on comma. To implement a proper parser for that case, you need to loop through the string yourself, keeping track of whether you are inside quotes or not. If you are inside a quoted string, you should keep on until you find another quote.

IEnumerable LineSplitter(string line)
{
    int fieldStart = 0;
    for(int i = 0; i < line.Length; i++)
    {
        if(line[i] == ',')
        {    
            yield return line.SubString(fieldStart, i - fieldStart);
            fieldStart = i + 1;
        }
        if(line[i] == '"')
            for(i++; line[i] != '"'; i++) {}
    }
}
