Tuple<T1,T2>.IStructuralEquatable.GetHashCode(IEqualityComparer) Method

Definition

Namespace:

System

Assembly:

System.Runtime.dll

Source:

Tuple.cs

Calculates the hash code for the current Tuple<T1,T2> object by using a specified computation method.

 virtual int System.Collections.IStructuralEquatable.GetHashCode(System::Collections::IEqualityComparer ^ comparer) = System::Collections::IStructuralEquatable::GetHashCode;

int IStructuralEquatable.GetHashCode (System.Collections.IEqualityComparer comparer);

abstract member System.Collections.IStructuralEquatable.GetHashCode : System.Collections.IEqualityComparer -> int
override this.System.Collections.IStructuralEquatable.GetHashCode : System.Collections.IEqualityComparer -> int

Function GetHashCode (comparer As IEqualityComparer) As Integer Implements IStructuralEquatable.GetHashCode

Parameters

comparer

IEqualityComparer

An object whose GetHashCode(Object) method calculates the hash code of the current Tuple<T1,T2> object.

Returns

Int32

A 32-bit signed integer hash code.

Implements

GetHashCode(IEqualityComparer)

Remarks

This member is an explicit interface member implementation. It can be used only when the Tuple<T1,T2> 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> objects that are considered to be equal.
