Syntax

public readonly struct InvocationList<TDelegate> : IReadOnlyList<TDelegate>, IReadOnlyCollection<TDelegate>, IEnumerable<TDelegate>, IEnumerable where TDelegate : MulticastDelegate

Type Parameters

Name	Description
TDelegate	The type of delegates in the list.

Remarks

This type can be used to store a list of event handlers in situations when the delegate type allows variance. In this case, Combine(params Delegate[]) may not be applicable due to lack of variance support.

Constructors

InvocationList(TDelegate)

Creates a new list containing a single element.

Declaration

public InvocationList(TDelegate d)

Parameters

Type	Name	Description
TDelegate	d	The delegate to add.

Properties

Count

Gets the number of delegates in this list.

Declaration

public int Count { get; }

Property Value

Type	Description
int

Empty

Gets an empty list.

Declaration

public static InvocationList<TDelegate> Empty { get; }

Property Value

Type	Description
InvocationList<TDelegate>

IsEmpty

Indicates that this list is empty.

Declaration

public bool IsEmpty { get; }

Property Value

Type	Description
bool

this[int]

Gets the element at the specified index in the read-only list.

Declaration

public TDelegate this[int index] { get; }

Parameters

Type	Name	Description
int	index	The zero-based index of the element to get.

Property Value

Type	Description
TDelegate	The element at the specified index in the read-only list.

Span

Gets a span over list of delegates.

Declaration

Combine()

Combines the delegates in the list to a single delegate.

Declaration

public TDelegate? Combine()

Returns

Type	Description
TDelegate	A list of delegates combined as a single delegate.

GetEnumerator()

Gets enumerator over all delegates in this list.

Declaration

Returns

Type	Description
InvocationList<TDelegate>	The modified list of delegates.

Operators

operator +(InvocationList<TDelegate>, TDelegate?)

Addes the delegate to the list and returns modified list.

Declaration

public static InvocationList<TDelegate> operator +(InvocationList<TDelegate> list, TDelegate? d)

Parameters

Type	Name	Description
InvocationList<TDelegate>	list	The list of delegates.
TDelegate	d	The delegate to add.
