As you can see one of the column contains , <= (Corvallis, OR)
update
Based on C# Regex Split - commas outside quotes
string[] result = Regex.Split(samplestring, ",(?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)");
Use the Microsoft.VisualBasic.FileIO.TextFieldParser
class. This will handle parsing a delimited file, TextReader
or Stream
where some fields are enclosed in quotes and some are not.
For example:
using Microsoft.VisualBasic.FileIO;
string csv = "2,1016,7/31/2008 14:22,Geoff Dalgas,6/5/2011 22:21,http://stackoverflow.com,\"Corvallis, OR\",7679,351,81,b437f461b3fd27387c5d8ab47a293d35,34";
TextFieldParser parser = new TextFieldParser(new StringReader(csv));
// You can also read from a file
// TextFieldParser parser = new TextFieldParser("mycsvfile.csv");
parser.HasFieldsEnclosedInQuotes = true;
parser.SetDelimiters(",");
string[] fields;
while (!parser.EndOfData)
{
fields = parser.ReadFields();
foreach (string field in fields)
{
Console.WriteLine(field);
}
}
parser.Close();
This should result in the following output:
2 1016 7/31/2008 14:22 Geoff Dalgas 6/5/2011 22:21 http://stackoverflow.com Corvallis, OR 7679 351 81 b437f461b3fd27387c5d8ab47a293d35 34
See Microsoft.VisualBasic.FileIO.TextFieldParser for more information.
You need to add a reference to Microsoft.VisualBasic
in the Add References .NET tab.
