Summary

Encapsulates an IEqualityComparer<T> that uses an equality comparison function provided as a delegate.

Generic type parameters

T	The type of elements to be compared for equality.

Constructors

CustomEqualityComparer<T>(Func<T, T, bool> comparison, Func<T, int> getHashCode)	Constructor.
CustomEqualityComparer<T>(Func<T, T, bool> comparison)	Constructor which re-uses the default hash function. Use this overload only if using the objects’ original hash function is appropriate for this equality comparison.

Static methods

CustomEqualityComparer<T>	By(Func<T, string> selector, bool ignoreCase)	Creates and returns an equality comparer that compares the equality of objects by comparing the equality of the result of a string selector function.
CustomEqualityComparer<T>	By<TBy>(Func<T, TBy> selector, IEqualityComparer<TBy> comparer)	Creates and returns an equality comparer that compares the equality of objects by comparing the equality of the result of a selector function.
CustomEqualityComparer<T>	By<TBy>(Func<T, TBy> selector, Func<TBy, TBy, bool> comparison = null, Func<TBy, int> getHashCode = null)

Instance methods

bool	Equals(T x, T y) Implements: IEqualityComparer<T>.Equals(T, T)	Compares two elements for equality. (see also remarks)
int	GetHashCode(T obj) Implements: IEqualityComparer<T>.GetHashCode(T)	Returns a hash code for an element. (see also remarks)
