Syntax

public static class IEnumerableExtensions : Object

Methods

ContainsVoucherApplicationResultingToZeroAmount(IEnumerable<ReceiptItem>)

Declaration

public static bool ContainsVoucherApplicationResultingToZeroAmount(this IEnumerable<ReceiptItem> items)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<ReceiptItem>	items

Returns

Type	Description
System.Boolean

DistinctBy<TSource, TKey>(IEnumerable<TSource>, Func<TSource, TKey>)

Returns all distinct elements of the given source, where "distinctness" is determined via a projection and the default equality comparer for the projected type.

Declaration

public static IEnumerable<TSource> DistinctBy<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<TSource>	source	Source sequence
System.Func<TSource, TKey>	keySelector	Projection for determining "distinctness"

Returns

Type	Description
System.Collections.Generic.IEnumerable<TSource>	A sequence consisting of distinct elements from the source sequence, comparing them by the specified key projection.

Type Parameters

Name	Description
TSource	Type of the source sequence
TKey	Type of the projected element

Remarks

This operator uses deferred execution and streams the results, although a set of already-seen keys is retained. If a key is seen multiple times, only the first element with that key is returned.

DistinctBy<TSource, TKey>(IEnumerable<TSource>, Func<TSource, TKey>, IEqualityComparer<TKey>)

Returns all distinct elements of the given source, where "distinctness" is determined via a projection and the specified comparer for the projected type.

Declaration

public static IEnumerable<TSource> DistinctBy<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector, IEqualityComparer<TKey> comparer)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<TSource>	source	Source sequence
System.Func<TSource, TKey>	keySelector	Projection for determining "distinctness"
System.Collections.Generic.IEqualityComparer<TKey>	comparer	The equality comparer to use to determine whether or not keys are equal. If null, the default equality comparer for TSource is used.

Returns

Type	Description
System.Collections.Generic.IEnumerable<TSource>	A sequence consisting of distinct elements from the source sequence, comparing them by the specified key projection.

Type Parameters

Name	Description
TSource	Type of the source sequence
TKey	Type of the projected element

Remarks

This operator uses deferred execution and streams the results, although a set of already-seen keys is retained. If a key is seen multiple times, only the first element with that key is returned.
