Definition

Namespace:

System

Assembly:

System.Memory.dll

Overloads

Contains(ReadOnlySpan<Char>, ReadOnlySpan<Char>, StringComparison)	Indicates whether a specified value occurs within a read-only character span.
Contains<T>(ReadOnlySpan<T>, T)	Indicates whether a specified value is found in a read-only span. Values are compared using IEquatable{T}.Equals(T).
Contains<T>(Span<T>, T)	Indicates whether a specified value is found in a span. Values are compared using IEquatable{T}.Equals(T).

Contains(ReadOnlySpan<Char>, ReadOnlySpan<Char>, StringComparison)

Source:

MemoryExtensions.Globalization.cs

Indicates whether a specified value occurs within a read-only character span.

public:
[System::Runtime::CompilerServices::Extension]
 static bool Contains(ReadOnlySpan<char> span, ReadOnlySpan<char> value, StringComparison comparisonType);

public static bool Contains (this ReadOnlySpan<char> span, ReadOnlySpan<char> value, StringComparison comparisonType);

static member Contains : ReadOnlySpan<char> * ReadOnlySpan<char> * StringComparison -> bool

<Extension()>
Public Function Contains (span As ReadOnlySpan(Of Char), value As ReadOnlySpan(Of Char), comparisonType As StringComparison) As Boolean

Parameters

span

ReadOnlySpan<Char>

The source span.

value

ReadOnlySpan<Char>

The value to seek within the source span.

comparisonType

StringComparison

An enumeration value that determines how the characters in span and value are compared.

Returns

Boolean

true if value occurs within the span, false otherwise.

Contains<T>(ReadOnlySpan<T>, T)

Source:

MemoryExtensions.cs

Indicates whether a specified value is found in a read-only span. Values are compared using IEquatable{T}.Equals(T).

public:
generic <typename T>
 where T : IEquatable<T>[System::Runtime::CompilerServices::Extension]
 static bool Contains(ReadOnlySpan<T> span, T value);

public static bool Contains<T> (this ReadOnlySpan<T> span, T value) where T : IEquatable<T>;

static member Contains : ReadOnlySpan<'T (requires 'T :> IEquatable<'T>)> * 'T -> bool (requires 'T :> IEquatable<'T>)

<Extension()>
Public Function Contains(Of T As IEquatable(Of T)) (span As ReadOnlySpan(Of T), value As T) As Boolean

Type Parameters

T

The type of the span.

Parameters

span

ReadOnlySpan<T>

The span to search.

value

T

The value to search for.

Returns

Boolean

true if found, false otherwise.

Contains<T>(Span<T>, T)

Source:

MemoryExtensions.cs

Indicates whether a specified value is found in a span. Values are compared using IEquatable{T}.Equals(T).

public:
generic <typename T>
 where T : IEquatable<T>[System::Runtime::CompilerServices::Extension]
 static bool Contains(Span<T> span, T value);

public static bool Contains<T> (this Span<T> span, T value) where T : IEquatable<T>;

static member Contains : Span<'T (requires 'T :> IEquatable<'T>)> * 'T -> bool (requires 'T :> IEquatable<'T>)

<Extension()>
Public Function Contains(Of T As IEquatable(Of T)) (span As Span(Of T), value As T) As Boolean

Type Parameters

T

The type of the elements in the span.

Parameters

span

Span<T>

The span to search.

value

T

The value to search for.

Returns

Boolean

true if found, false otherwise.
