Tuple<T1, T2, T3, T4>.IStructuralEquatable.GetHashCode Method
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Calculates the hash code for the current Tuple<T1, T2, T3, T4> object by using a specified computation method.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Private Function GetHashCode ( _
comparer As IEqualityComparer _
) As Integer Implements IStructuralEquatable.GetHashCode
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> object.
Return Value
Type: System.Int32
A 32-bit signed integer hash code.

Remarks
This member is an explicit interface member implementation. It can be used only when the Tuple<T1, T2, T3, T4> 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> objects that are considered to be equal.
