Splitting Sting with Multiple Quotation Marks.

Hi, I'm using C#.NET 2010. -- I have a Sting that looks much like the format below.
I need to split it on the following three characters >   ","   < .  I cannot simply split it on the comma, because some of the parts of the Sting has commas in it.

Example:

"item_1, item_2, item_3, and item_4","item_5 and item_6, and item_7","item_8, item_9, item10"

So, in essence I have 3 basic parts to the larger String:

string1 = "item_1, item_2, item_3, and item_4"
string2 = "item_5 and item_6, and item_7"
string3 = "item_8, item_9, item10"

All 3 sub-strings are enclosed with quotation marks (") and separated by a comma (,).

How do I split on ---   ","  ?

I tried --  ' \",\" '    and    ' " , " '   and also   @","    but none of those worked.

Can someone please assist?

Thank you,
Fulano

There are many exsisting good CSV parsers that you can use. E.g.,  Microsoft.VisualBasic.FileIO.TextFieldParser (you need to add a reference).

E.g., you have a simple file test.csv:
-------------------------------------------
id, description, quantity
1,"hello, world", 1000
2, "a,b,c",2000
---------------------------------------------------

Sample code:

        private void button4_Click(object sender, EventArgs e)
        {
            Microsoft.VisualBasic.FileIO.TextFieldParser parser = new Microsoft.VisualBasic.FileIO.TextFieldParser("test.csv");
            parser.SetDelimiters(new string[] { "<", ",", ">" });
            parser.HasFieldsEnclosedInQuotes = true;

            int counter = 0;
            while (true) // read line by line and check number of fields 
            {
                counter += 1;
                string[] fields = parser.ReadFields();
                if (fields == null)
                {
                    break;
                }
                // just print how many fields in each line
                System.Diagnostics.Debug.WriteLine("Line {0}: {1} field(s)", counter, fields.Length);
            }
        }

here an example:

 string str = "\"item_1, item_2, item_3, and item_4\",\"item_5 and item_6, and item_7\",\"item_8, item_9, item10\"";
var tokens = str.Split('"').Where((s, i) => i % 2 != 0);
