Answer 1

I would say, forget about regex. CSV can be parsed easily by TextFieldParser class. To do that, you need to be

using Microsoft.VisualBasic.FileIO;

Then you can use it:

  using (TextFieldParser parser = new TextFieldParser(Stream))
  {
    parser.TextFieldType = FieldType.Delimited;
    parser.SetDelimiters(",");

    while (!parser.EndOfData)
    {
      string[] fields = parser.ReadFields();
      foreach (string field in fields)
      {
         // Do your stuff here ...
      }
    }
  }
