Definition

Namespace:

System

Assembly:

System.Runtime.dll

Source:

Tuple.cs

Gets the value of the current Tuple<T1,T2,T3,T4> object's third component.

public:
 property T3 Item3 { T3 get(); };

public T3 Item3 { get; }

member this.Item3 : 'T3

Public ReadOnly Property Item3 As T3

Property Value

T3

The value of the current Tuple<T1,T2,T3,T4> object's third component.

Examples

The following example defines an array of Tuple<T1,T2,T3,T4> objects whose components contain the name of a city, a month of the year, and the average high and low temperatures for that month. It then retrieves and displays the value of each component.

Remarks

You can dynamically determine the type of the Item3 component in one of two ways:

• By calling the GetType method on the value that is returned by the Item3 property.

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