Determines whether two converted collections are same.

Declaration

public override bool Equals(object? other)

Parameters

Type	Name	Description
object	other	Other collection to compare.

Returns

Type	Description

Parameters

Type	Name	Description
ReadOnlyCollectionView<TInput, TOutput>	first	The first collection to compare.
ReadOnlyCollectionView<TInput, TOutput>	second	The second collection to compare.

Returns

Type	Description
bool	true if the first view wraps the same source collection and contains the same converter as the second view; otherwise, false.

operator !=(in ReadOnlyCollectionView<TInput, TOutput>, in ReadOnlyCollectionView<TInput, TOutput>)

Determines whether two collections are not same.

Declaration
