EnumerableExtensions

Methods

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

Executes an action for each item of the given enumerable.

public static void ForEach<T>(this IEnumerable<T> source, Action<T> action)

Parameters

source IEnumerable<T>

Input enumerable to work on.

action Action<T>

Action performed for each item in the enumerable.

Type Parameters

T

Type of the item value in the enumerable.

Remarks

This extension method do not yield. It acts just like a foreach statement.

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

Executes an action for each (casted) item of the given enumerable.

public static void ForEach<T>(this IEnumerable source, Action<T> action)

Parameters

source IEnumerable

Input enumerable to work on.

action Action<T>

Action performed for each item in the enumerable.

Type Parameters

T

Type of the item value in the enumerable.

Remarks

This extension method do not yield. It acts just like a foreach statement, and performs a cast to a typed enumerable in the middle.

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

An IEnumerable<T> extension method that searches for the first match and returns its index.

[Pure]
public static int IndexOf<T>(this IEnumerable<T> source, Func<T, bool> predicate)

Parameters

source IEnumerable<T>

Input enumerable to work on.

predicate Func<T, bool>

The predicate.

Returns

int

The index of the first element matching.

Type Parameters

T

Generic type parameter.

IsNullOrEmpty(IEnumerable)

Tells whether a sequence is null or empty.

[Pure]
public static bool IsNullOrEmpty(this IEnumerable source)

Parameters

source IEnumerable

The source sequence.

Returns

bool

Returns true if the sequence is null or empty, false if it is not null and contains at least one element.

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

An IEnumerable<T> extension method that searches for the last match and returns its index.

[Pure]
public static int LastIndexOf<T>(this IEnumerable<T> source, Func<T, bool> predicate)

Parameters

source IEnumerable<T>

Input enumerable to work on.

predicate Func<T, bool>

The predicate.

Returns

int

The index of the last element matching.

Type Parameters

T

Generic type parameter.

NotNull<T>(IEnumerable<T?>)

Filters out null items from the enumerable.

[Pure]
public static IEnumerable<T> NotNull<T>(this IEnumerable<T?> source) where T : struct

Parameters

source IEnumerable<T?>

Input enumerable to work on.

Returns

IEnumerable<T>

An enumeration of all items in source that are not null.

Type Parameters

T

Generic type parameter.

NotNull<T>(IEnumerable<T>)

Filters out null items from the enumerable.

[Pure]
public static IEnumerable<T> NotNull<T>(this IEnumerable<T> source) where T : class

Parameters

source IEnumerable<T>

Input enumerable to work on.

Returns

IEnumerable<T>

An enumeration of all items in source that are not null.

Type Parameters

T

Generic type parameter.

ToHashCode<T>(IEnumerable<T>)

Calculates a combined hash code for items of the enumerbale.

[Pure]
public static int ToHashCode<T>(this IEnumerable<T> source) where T : class

Parameters

source IEnumerable<T>

Input enumerable to work on.

Returns

int

A combined hash code or 0 if the source is empty.

Type Parameters

T

Generic type parameter.
