使用String.Split（）分割字符串

Question

Im trying to split a string into sub parts to pass into a linq database, but ive come up with a problem. The file is a .csv file so its split up by commas example :

1,Ms,Aleshia,Tomkiewicz,14 Taylor St,St. Stephens Ward,Kent,CT2 7PP,01835-703597,atomkiewicz@hotmail.com.

However some of the data contains commas in the data field like a county/address is split up with a comma however i dont want it to split i want it to keep that data all together for example address: London,Wimbledon.

im using this code currently to do the chopping:


 public static List<string> ReturnCSVFromWeb(string url)
        {
            System.Net.WebClient client = new WebClient();
            string CSVContent = client.DownloadString(url);

            List<string> splitted = new List<string>();
            string csvFile = CSVContent;
            string[] tempStr;

            tempStr = csvFile.Split(',','\n');

            foreach (string item in tempStr)
            {
                if (!string.IsNullOrWhiteSpace(item))
                {
                    splitted.Add(item);
                }
            }

            return splitted;

        }

Answer 1

There is no way to solve this problem unless you know ahead of time which data contains commas. A better option would be to have each entry in the csv surrounded by double quote, and then seperated by comma

Answer 2

If number of rows is fixed ( M ) and only address column has comma, you can do this:

1. Split row
2. Take first N1 columns before address
3. Take last N2 columns after address
4. Take M-N1-N2 columns from middle, join them - it's an address
