Tuple<T1, T2, T3, T4, T5, T6>.Item3 Property
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets the value of the current Tuple<T1, T2, T3, T4, T5, T6> object's third component.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public ReadOnly Property Item3 As T3
public T3 Item3 { get; }
Property Value
Type: T3
The value of the current Tuple<T1, T2, T3, T4, T5, T6> object's third 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, T5, T6> object, and retrieving the first element from the array that is returned by its Type.GetGenericArguments method.
Examples
The following example defines an array of Tuple<T1, T2, T3, T4, T5, T6> objects whose components contain population data for three U.S. cities (New York, Chicago, and Los Angeles) from 1960 through 2000. It then displays a table that lists the data. To display the population in 1970, it retrieves the value of the Item3 property for each Tuple<T1, T2, T3, T4, T5, T6> object.
