C# || How To Parse A Delimited CSV File Using C#

Print Friendly, PDF & Email

The following is a module with functions which demonstrates how to parse a delimited CSV file using VB.NET.

This function parses a CSV file and returns its results as a List. Each List index represents a line in the CSV file, with each item in the list representing a record contained on that line.

The function demonstrated on this page uses FileIO.TextFieldParser to parse values in a CSV file.

Note: To use the function in this module, make sure you have a reference to ‘Microsoft.VisualBasic‘ in your project.

One way to do this is, in your Solution Explorer (where all the files are shown with your project), right click the ‘References‘ folder, click ‘Add Reference‘, then type ‘Microsoft.VisualBasic‘ in the search box, and add the reference titled Microsoft.VisualBasic in the results Tab.
