C# 0 The Complete Reference

join

. Recall that in the previous version, a class called 

Temp

was needed to encapsulate the result of the 

join

. Through the use of an anonymous type, 

this “placeholder” class is no longer needed and no longer clutters the source code to the 

program. The output from the program is unchanged from before.

// Use an anonymous type to improve the join demo program.

using System;

using System.Linq;

// A class that links an item name with its number.

class Item {

  public string Name { get; set; }

  public int ItemNumber { get; set; }

  public Item(string n, int inum) {

    Name = n;

    ItemNumber = inum;

  }

}

// A class that links an item number with its in-stock status.

class InStockStatus {

  public int ItemNumber { get; set; }

  public bool InStock { get; set; }

  public InStockStatus(int n, bool b) {

    ItemNumber = n;

    InStock = b;

  }

}
