How often did you have to read data separated, for example, by a comma (CSV format) from a file, process it and do something further with them?

Of course you can write the code yourself, but it will take time and not always be effective.

FileHelpers - a module that will help you. It can synchronously or asynchronously read data from a file into an object. It can also enter data back into the file with the specified delimiter. Can read data from a database. It has a bunch of all sorts of features, which can be found in more detail on the official website of this module.

Example of asynchronously reading data from a file

Suppose you have the following file with data separated by the "|" symbol:

10248 | VINET | 04071996 | 32.38
10249 | TOMSP | 05071996 | 11.61
10250 | HANAR | 08071996 | 65.83
10251 | VICTE | 08071996 | 41.34
...............

You need to create a class that describes the file data structure:

 [DelimitedRecord ("|")] // Define the separator
 public class Orders
 {
   public int OrderID;

   public string CustomerID;

   [FieldConverter (ConverterKind.Date, "ddMMyyyy")]
   public DateTime OrderDate;

   public decimal Freight;
 } * This source code was highlighted with Source Code Highlighter .

Now read the data asynchronously:

  FileHelperAsyncEngine engine = new FileHelperAsyncEngine (typeof (Orders));

  engine.BeginReadFile ("TestIn.txt");

  // The engine is IEnumerable
  foreach (Orders ord in engine)
  {
    // your code here
    Console.WriteLine (ord.CustomerID);
  }

  engine.Close ();

That's all.
