public T1 Item1 { get; }

Property Value

Type: T1
The value of the current Tuple<T1, T2, T3, T4, T5> object's first component.

You can dynamically determine the type of the Item1 component in one of two ways:

  • By calling the GetType method on the value that is returned by the Item1 property.

  • By retrieving the Type object that represents the Tuple<T1, T2, T3, T4, T5> object, and retrieving the first element from the array that is returned by its Type.GetGenericArguments method.

The following example defines an array of Tuple<T1, T2, T3, T4, T5> objects whose components contain the name of a state in the United States, its population in 1990 and 2000, its population change in this 10-year period, and the percentage change in its population. It then iterates through the array and displays the value of each component in a tuple.
