MemoryMarshal.Write<T>(Span<Byte>, T) Method

Definition

Namespace:

System.Runtime.InteropServices

Assembly:

System.Memory.dll

Source:

MemoryMarshal.cs

Writes a structure of type T into a span of bytes.

public:
generic <typename T>
 where T : value class static void Write(Span<System::Byte> destination, T % value);

public static void Write<T> (Span<byte> destination, in T value) where T : struct;

static member Write : Span<byte> * 'T -> unit (requires 'T : struct)

Public Shared Sub Write(Of T As Structure) (destination As Span(Of Byte), ByRef value As T)

Type Parameters

T

The type of the structure.

Parameters

destination

Span<Byte>

The span of bytes to contain the structure.

value

T

The structure to be written to the span.

Exceptions

ArgumentException

T contains managed object references.

ArgumentOutOfRangeException

destination is too small to contain value.

Remarks

T cannot contain managed object references. The Write method performs this check at runtime and throws ArgumentException if the check fails.

Caution

This method copies raw binary data from the original span, including any private instance fields and other implementation details of type T. Callers should ensure that their code is resilient to changes in the internal layout of T.
