Parameters:sourceIEnumerable<T>

A sequence to return elements from.

otherT

An element to be included in the sequence.

Returns:

IEnumerable<T>

An System.Collections.Generic.IEnumerable(T) that contains the elements from the input sequences and appends it with the other element.

RemoveAll(IList, Predicate<object>)

Removes all elements from a list that match the condition defined by the specified predicate.

C#
public static int RemoveAll(this IList list, Predicate<object> match)
Parameters:listIList

The list, which elements will be removed.

matchPredicate<object>

The predicate delegate that defines the condition for the removed elements.

Returns:

int

Number of the removed elements.

RemoveAll<T>(ICollection<T>, Predicate<T>)

Removes all elements from a collection that match the condition defined by the specified predicate.

C#
public static int RemoveAll<T>(this ICollection<T> collection, Predicate<T> match)
Parameters:collectionICollection<T>

The collection, which elements will be removed.

matchPredicate<T>

The predicate delegate that defines the condition for the removed elements.

Returns:

int

Number of removed elements.

RemoveAll<T>(IList<T>)

Removes all elements from the given collection.

C#
public static void RemoveAll<T>(this IList<T> collection)
Parameters:collectionIList<T>

The collection, which will be emptied.

TakeAfter<T>(IEnumerable<T>, Func<T, bool>)

Bypasses elements from a sequence as long as a specified condition is true and then returns the remaining elements.

C#
public static IEnumerable<T> TakeAfter<T>(this IEnumerable<T> target, Func<T, bool> predicate)
Parameters:targetIEnumerable<T>

A sequence to return elements from.

predicateFunc<T, bool>

A function to test each element for a condition.

Returns:

IEnumerable<T>

An System.Collections.Generic.IEnumerable(T) that contains the elements from the input sequence that occur after the element at which the test no longer passes.

TakeBefore<T>(IEnumerable<T>, Func<T, bool>)

Bypasses elements from a sequence until the specified condition becomes true.

C#
public static IEnumerable<T> TakeBefore<T>(this IEnumerable<T> target, Func<T, bool> predicate)
Parameters:targetIEnumerable<T>

A sequence to return elements from.

predicateFunc<T, bool>

A function to test each element for a condition.

Returns:

IEnumerable<T>

An System.Collections.Generic.IEnumerable(T) that contains the elements from the input sequence that occur before the element at which the test no longer passes.

TakeBetween<T>(IEnumerable<T>, Func<T, bool>, Func<T, bool>)

Bypasses elements from a sequence as long as the first condition is false. Returns elements from the remaining elements as long the second condition is false.

C#
public static IEnumerable<T> TakeBetween<T>(this IEnumerable<T> target, Func<T, bool> predicate1, Func<T, bool> predicate2)
Parameters:targetIEnumerable<T>

A sequence to return elements from.

predicate1Func<T, bool>

A function to test each element for a condition.

predicate2Func<T, bool>

A function to test each element for a condition.

Returns:

IEnumerable<T>

An System.Collections.Generic.IEnumerable(T) that contains the elements from the input sequence that are between the elements that pass the test specified by the predicates.

TakeBetween<T>(IEnumerable<T>, T, T)

Returns elements from a sequence as long as they are between the two items.

C#
public static IEnumerable<T> TakeBetween<T>(this IEnumerable<T> target, T item1, T item2)
Parameters:targetIEnumerable<T>

A sequence to return elements from.

item1T

The first item.

item2T

The second item.

Returns:

IEnumerable<T>

An System.Collections.Generic.IEnumerable(T) that contains the elements between the two items including.

TakeFrom<T>(IEnumerable<T>, Func<T, bool>)

Bypasses elements from a sequence as long as a specified condition is false and then returns the element that satisfies the condition and the elements after.

C#
public static IEnumerable<T> TakeFrom<T>(this IEnumerable<T> target, Func<T, bool> predicate)
Parameters:targetIEnumerable<T>

A sequence to return elements from.

predicateFunc<T, bool>
