I just had a project that required us to download a file from a vendor and parse the CSV file and place it into an SQL database. Unfortunately, this is an issue in my case as the vendor is senting up the CSV file to have each row encased in double quotes. This is because their description has commas in it. To do this i had two options.
Option 1 was to code all of it by scratch and i found a very nice tutorial on how to do this here <a href="http://www.blackbeltcoder.com/Articles/files/reading-and-writing-csv-files-in-c"> Parse CSV file with Double quotes</a>
Option 2 is to use TextFieldParser in the Microsoft.VisualBasic namespace ( Yes you can implement this even in C#). Here is an example using TextFieldParser:
public void Parser()
string pathFile = @"C:\TestFolder\TestCatalog.txt";
string line = "";
TextFieldParser fieldParser = null;
fieldParser = new TextFieldParser(pathFile);
string array = fieldParser.ReadFields();
while ((line = fieldParser.ReadLine()) != null)
MessageBox.Show("This line: " + line);
catch (Exception ex)
MessageBox.Show("Caught Exception: " + ex);
if (fieldParser != null)
The above uses the comma as the delimiter because even though they are using the quotes, you still have the carriage return and the end of a line has no comma dictating end of row. For Example: "Gregg","Test","Software"
As you can see above, Software ends the row with no comma after the end double quote.
