How Can I Efficiently Parse CSV Data in .NET?

Parsing CSV Data in .NET

Reading CSV (Comma-Separated Value) files is a common task when dealing with data in .NET applications. There are several approaches you can consider:

Using Microsoft.VisualBasic.FileIO.TextFieldParser:

This built-in class offers a straightforward way to parse CSV files without relying on third-party components. To use it, follow these steps:

1. Import the Microsoft.VisualBasic assembly.
2. Create an instance of TextFieldParser, specifying the file to be parsed.
3. Set the TextFieldType to Delimited.
4. Define the delimiters used in the CSV file (e.g., ",", ";").

Once configured, you can iterate through the file's rows using the ReadFields() method and access the individual values in each row.

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

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