Tuple<T1, T2>.Item2 Property

Gets the value of the current Tuple<T1, T2> object's second component.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public T2 Item2 { get; }

Property Value

Type: T2
The value of the current Tuple<T1, T2> object's second component.

You can dynamically determine the type of the Item2 component in one of two ways:

  • By calling the GetType method on the value that is returned by the Item2 property.

  • By retrieving the Type object that represents the Tuple<T1, T2> object, and retrieving the second element from the array that is returned by its Type.GetGenericArguments method.

The example illustrates the use of the Item1 and Item2 properties to define a method that returns multiple values in the form of a 2-tuple.


using System;

public class Class1
{
   public static void Main()
   {
      int dividend, divisor;
      Tuple<int, int> result;

      dividend = 136945; divisor = 178;
      result = IntegerDivide(dividend, divisor);
      if (result != null)
         Console.WriteLine(@"{0} \ {1} = {2}, remainder {3}", 
                           dividend, divisor, result.Item1, result.Item2);
      else
         Console.WriteLine(@"{0} \ {1} = <Error>", dividend, divisor);

      dividend = Int32.MaxValue; divisor = -2073;
      result = IntegerDivide(dividend, divisor);
      if (result != null)
         Console.WriteLine(@"{0} \ {1} = {2}, remainder {3}", 
                           dividend, divisor, result.Item1, result.Item2);
      else
         Console.WriteLine(@"{0} \ {1} = <Error>", dividend, divisor);
   }

   private static Tuple<int, int> IntegerDivide(int dividend, int divisor)
   {
      try {
         int remainder;
         int quotient = Math.DivRem(dividend, divisor, out remainder);
         return new Tuple<int, int>(quotient, remainder);
      }   
      catch (DivideByZeroException) {
         return null;
      }      
   }
}
// The example displays the following output:
//       136945 \ 178 = 769, remainder 63
//       2147483647 \ -2073 = -1035930, remainder 757
