C# – Parsing CSV files in C#, with header

c++csvfile-ioheaderio

Is there a default/official/recommended way to parse CSV files in C#? I don't want to roll my own parser.

Also, I've seen instances of people using ODBC/OLE DB to read CSV via the Text driver, and a lot of people discourage this due to its "drawbacks." What are these drawbacks?

Ideally, I'm looking for a way through which I can read the CSV by column name, using the first record as the header / field names. Some of the answers given are correct but work to basically deserialize the file into classes.

Best Solution

A CSV parser is now a part of .NET Framework.

Add a reference to Microsoft.VisualBasic.dll (works fine in C#, don't mind the name)

using (TextFieldParser parser = new TextFieldParser(@"c:\temp\test.csv"))
{
    parser.TextFieldType = FieldType.Delimited;
    parser.SetDelimiters(",");
    while (!parser.EndOfData)
    {
        //Process row
        string[] fields = parser.ReadFields();
        foreach (string field in fields)
        {
            //TODO: Process field
        }
    }
}
