Name Description
LastIndexOf<T>(Span<T>, T)

Searches for the specified value and returns the index of its last occurrence.

LastIndexOf<T>(Span<T>, ReadOnlySpan<T>)

Searches for the specified sequence and returns the index of its last occurrence.

LastIndexOf<T>(ReadOnlySpan<T>, T)

Searches for the specified value and returns the index of its last occurrence.

LastIndexOf<T>(ReadOnlySpan<T>, ReadOnlySpan<T>)

Searches for the specified sequence and returns the index of its last occurrence.

LastIndexOf<T>(Span<T>, T)

Searches for the specified value and returns the index of its last occurrence.

public:
generic <typename T>
 where T : IEquatable<T>[System::Runtime::CompilerServices::Extension]
 static int LastIndexOf(Span<T> span, T value);
public static int LastIndexOf<T>(this Span<T> span, T value) where T : IEquatable<T>;
static member LastIndexOf : Span<'T (requires 'T :> IEquatable<'T>)> * 'T -> int (requires 'T :> IEquatable<'T>)
<Extension()>
Public Function LastIndexOf(Of T As IEquatable(Of T)) (span As Span(Of T), value As T) As Integer

Type Parameters

T

The type of the span and value.

Parameters

span
Span<T>

The span to search.

value
T

The value to search for.

Returns

The index of the last occurrence of the value in the span. If not found, returns -1.

Remarks

Values are compared using IEquatable{T}.Equals(T).

Applies to

LastIndexOf<T>(Span<T>, ReadOnlySpan<T>)

Searches for the specified sequence and returns the index of its last occurrence.

Type Parameters

T

The type of the span and value.

Parameters

span
Span<T>

The span to search.

value
ReadOnlySpan<T>

The sequence to search for.

Returns

The index of the last occurrence of the value in the span. If not found, returns -1.

Remarks

Values are compared using IEquatable{T}.Equals(T).
