Represents a contiguous region of memory.

generic <typename T>
public value class Memory : IEquatable<Memory<T>>
generic <typename T>
public value class Memory
public readonly struct Memory<T> : IEquatable<Memory<T>>
public readonly struct Memory<T>
type Memory<'T> = struct
Public Structure Memory(Of T)
Implements IEquatable(Of Memory(Of T))
Public Structure Memory(Of T)

Type Parameters

T

The type of items in the Memory<T>.

Inheritance
Object
ValueType
Memory<T>
Implements
IEquatable<Memory<T>>

Remarks

Like Span<T>, Memory<T> represents a contiguous region of memory. Unlike Span<T>, however, Memory<T> is not a ref struct. This means that Memory<T> can be placed on the managed heap, whereas Span<T> cannot. As a result, the Memory<T> structure does not have the same restrictions as a Span<T> instance. In particular:

  • It can be used as a field in a class.

  • It can be used across await and yield boundaries.

In addition to Memory<T>, you can use System.ReadOnlyMemory<T> to represent immutable or read-only memory.

Constructors

Memory<T>(T[], Int32, Int32)

Creates a new Memory<T> object that includes a specified number of elements of an array beginning at a specified index.
Memory<T>(T[])

Creates a new Memory<T> object over the entirety of a specified array.

Properties

Empty

Returns an empty Memory<T> object.
IsEmpty

Indicates whether the current instance is empty.
Length

Gets the number of items in the current instance.
Span

Returns a span from the current instance.

Methods

CopyTo(Memory<T>)

Copies the contents of a Memory<T> object into a destination Memory<T> object.
Equals(Memory<T>)

Determines whether the specified Memory<T> object is equal to the current object.
Equals(Object)

Determines whether the specified object is equal to the current object.
GetHashCode()

Returns the hash code for this instance.
Pin()

Creates a handle for the Memory<T> object.
Slice(Int32, Int32)

Forms a slice out of the current memory starting at a specified index for a specified length.
Slice(Int32)

Forms a slice out of the current memory that begins at a specified index.
ToArray()

Copies the contents from the memory into a new array.
ToString()

Returns the string representation of this Memory<T> object.
TryCopyTo(Memory<T>)

Copies the contents of the memory into a destination Memory<T> instance.

Operators

Implicit(ArraySegment<T> to Memory<T>)

Defines an implicit conversion of an ArraySegment<T> object to a Memory<T> object.
Implicit(Memory<T> to ReadOnlyMemory<T>)

Defines an implicit conversion of a Memory<T> object to a ReadOnlyMemory<T> object.
Implicit(T[] to Memory<T>)

Defines an implicit conversion of an array to a Memory<T> object.

Extension Methods

Trim<T>(Memory<T>, T)

Removes all leading and trailing occurrences of a specified element from a memory region.
Trim<T>(Memory<T>, ReadOnlySpan<T>)

Removes all leading and trailing occurrences of a set of elements specified in a read-only span from a memory region.
TrimEnd<T>(Memory<T>, T)

Removes all trailing occurrences of a specified element from a character memory region.
TrimEnd<T>(Memory<T>, ReadOnlySpan<T>)

Removes all trailing occurrences of a set of elements specified in a read-only span from a memory region.
TrimStart<T>(Memory<T>, T)

Removes all leading occurrences of a specified element from a memory region.
TrimStart<T>(Memory<T>, ReadOnlySpan<T>)

Removes all leading occurrences of a set of elements specified in a read-only span from a memory region.
