Syntax

public static class EnumerableExtensions

Methods

AddRange<T>(ICollection<T>, IEnumerable<T>)

Adds the elements of the specified values to the end of the System.Collections.Generic.ICollection<T>.

Declaration

public static void AddRange<T>(this ICollection<T> collection, IEnumerable<T> values)

Parameters

System.Collections.Generic.ICollection<T> collection The collection to added values to.

IEnumerable<T> values The values that should be added to the end of the ICollection{T}. The values itself cannot be null, but it can contain elements that are null, if type T is a reference type.

Type Parameters

T The type of elements in the collection.

Each<T>(IEnumerable<T>, Action<T>)

Iterates all items and performs an action.

Declaration

public static void Each<T>(this IEnumerable<T> items, Action<T> action)

Parameters

IEnumerable<T> items The collection of items to iterate.

System.Action<T> action The action to perform for each item.

Type Parameters

T The type of item.

FindMissingNumbersInSequence<T>(IEnumerable<T>, Boolean)

Take a sequence of numbers and report the missing numbers.

Declaration

public static IEnumerable<T> FindMissingNumbersInSequence<T>(this IEnumerable<T> sequence, bool autoOrder = true)
    where T : struct, IComparable, IComparable<T>, IConvertible, IEquatable<T>, IFormattable

Parameters

IEnumerable<T> sequence Set of numbers

Boolean autoOrder True to autorder the sequence; otherwise false, the default value is true.

Returns

IEnumerable<T> Returns any missing numbers in the sequence.

Type Parameters

T

FindMissingNumbersInSequence<TSource, TResult>(IEnumerable<TSource>, Func<TSource, TResult>, Boolean)

Takes a collection of items and report the missing numbers in the collection.

Declaration

public static IEnumerable<TResult> FindMissingNumbersInSequence<TSource, TResult>(this IEnumerable<TSource> sequence, Func<TSource, TResult> selector, bool autoOrder = true)
    where TSource : class where TResult : struct, IComparable, IComparable<TResult>, IConvertible, IEquatable<TResult>, IFormattable

Parameters

IEnumerable<TSource> sequence A collection of items.

System.Func<TSource, TResult> selector A function used to transform a numeric property from each item in the collection.

Boolean autoOrder True to autorder the items; otherwise false, the default value is true.

Returns

IEnumerable<TResult> Returns any missing numbers in the collection.

Type Parameters

TSource

TResult

FindNumbersBeforeNumbersOutOfSequence<T>(IEnumerable<T>, Boolean)

Finds the last number in sequence before numbers that are out of sequence.

Declaration

public static IEnumerable<T> FindNumbersBeforeNumbersOutOfSequence<T>(this IEnumerable<T> sequence, bool autoOrder = true)
    where T : struct, IComparable, IComparable<T>, IConvertible, IEquatable<T>, IFormattable

Parameters

IEnumerable<T> sequence Set of numbers

Boolean autoOrder True to autorder the sequence; otherwise false, the default value is true.

Returns

IEnumerable<T> The list of break numbers which exist before the missing numbers.

Type Parameters

T

FindNumbersBeforeNumbersOutOfSequence<TSource, TResult>(IEnumerable<TSource>, Func<TSource, TResult>, Boolean)

Finds the last number in a collection of items before numbers that are out of sequence.

Declaration

public static IEnumerable<TSource> FindNumbersBeforeNumbersOutOfSequence<TSource, TResult>(this IEnumerable<TSource> sequence, Func<TSource, TResult> selector, bool autoOrder = true)
    where TSource : class where TResult : struct, IComparable, IComparable<TResult>, IConvertible, IEquatable<TResult>, IFormattable

Parameters

IEnumerable<TSource> sequence A collection of items.

System.Func<TSource, TResult> selector A function used to transform a numeric property from each item in the collection.

Boolean autoOrder True to autorder the items; otherwise false, the default value is true.

Returns

IEnumerable<TSource> The list of items which exist before the missing numbers.

Type Parameters
