Tuple<T1, T2, T3, T4, T5, T6, T7, TRest>.IStructuralEquatable.GetHashCode Method

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Calculates the hash code for the current Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object by using a specified computation method.

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

int IStructuralEquatable.GetHashCode(
	IEqualityComparer comparer
)

Parameters

comparer
Type: System.Collections.IEqualityComparer
An object whose IEqualityComparer.GetHashCode method calculates the hash code of the current Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object.

Return Value

Type: System.Int32
A 32-bit signed integer hash code.

Implements

IStructuralEquatable.GetHashCode(IEqualityComparer)

This member is an explicit interface member implementation. It can be used only when the Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> instance is cast to an IStructuralEquatable interface.

The method simply wraps a call to the comparer object's IEqualityComparer.GetHashCode implementation.

The algorithm used to compute the hash code should return the same hash code for two Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> objects that are considered to be equal.
