Syntax

public static class EnumerableExtensions

Methods

NonNull<T>(IEnumerable<T>)

LINQ-style extension method that filters null elements out of an enumeration.

Declaration

public static IEnumerable<T> NonNull<T>(this IEnumerable<T> self)
    where T : class

Parameters

Type	Name	Description
IEnumerable<T>	self	the enumeration to filter

Returns

Type	Description
IEnumerable<T>	a filtered enumerable

Type Parameters

Name	Description
T	the type of the enumeration

NonNull<T>(IEnumerable<Nullable<T>>)

LINQ-style extension method that filters null elements from an enumeration of nullable types.

Declaration

public static IEnumerable<T> NonNull<T>(this IEnumerable<T?> self)
    where T : struct

Parameters

Type	Name	Description
IEnumerable<Nullable<T>>	self	the enumeration to filter

Returns

Type	Description
IEnumerable<T>	a filtered enumerable

Type Parameters

Name	Description
T	the underlying type of the nullable enumeration

NonNull<T, U>(IEnumerable<T>, Func<T, U>)

LINQ-style extension method that filters null elements out of an enumeration based on a converter.

Declaration

public static IEnumerable<T> NonNull<T, U>(this IEnumerable<T> self, Func<T, U> pred)
    where U : class

Parameters

Type	Name	Description
IEnumerable<T>	self	the enumeration to filter
Func<T, U>	pred	the predicate to select for filtering

Returns

Type	Description
IEnumerable<T>	a filtered enumerable

Type Parameters

Name	Description
T	the type of the enumeration
U	the type to compare to null

NonNull<T, U>(IEnumerable<T>, Func<T, Nullable<U>>)

LINQ-style extension method that filters null elements out of an enumeration based on a converter to a nullable type.

Declaration

public static IEnumerable<T> NonNull<T, U>(this IEnumerable<T> self, Func<T, U?> pred)
    where U : struct

Parameters

Type	Name	Description
IEnumerable<T>	self	the enumeration to filter
Func<T, Nullable<U>>	pred	the predicate to select for filtering

Returns

Type	Description
IEnumerable<T>	a filtered enumerable

Type Parameters

Name	Description
T	the type of the enumeration
U	the type of the predicate's resulting nullable
