Equals(object?)

Determines whether two converted lists are same.

Declaration

public override bool Equals(object? other)

Parameters

Type	Name	Description
object	other	Other list to compare.

Returns

Type	Description
bool	true if this collection wraps the same source collection and contains the same converter as other collection; otherwise, false.

Overrides

ValueType.Equals(object)

GetEnumerator()

Returns enumerator over converted items.

Declaration

public IEnumerator<TOutput> GetEnumerator()

Returns

Type	Description
IEnumerator<TOutput>	The enumerator over converted items.

GetHashCode()
