How to Read a CSV File with Native .NET Functionality

Question:

How can I read a CSV file using C# without relying on third-party components?

Answer:

The .NET Framework provides the Microsoft.VisualBasic.FileIO.TextFieldParser class for parsing CSV files. To use this class, import the Microsoft.VisualBasic assembly.

Here's how to use the TextFieldParser to read a CSV file:

using Microsoft.VisualBasic.FileIO;

var parser = new TextFieldParser(file);
parser.TextFieldType = FieldType.Delimited;
parser.SetDelimiters(new string[] { ";" });

while (!parser.EndOfData)
{
    string[] row = parser.ReadFields();
    // Process the current row
}

The ReadFields method returns an array of strings representing the values of the current row in the CSV file.
