MemoryMarshal.Read<T>(ReadOnlySpan<Byte>) Method

Definition

Reads a structure of type T out of a read-only span of bytes.

public:
generic <typename T>
 where T : value class static T Read(ReadOnlySpan<System::Byte> source);
public static T Read<T> (ReadOnlySpan<byte> source) where T : struct;
static member Read : ReadOnlySpan<byte> -> 'T (requires 'T : struct)
Public Shared Function Read(Of T As Structure) (source As ReadOnlySpan(Of Byte)) As T

Type Parameters

T

The type of the item to retrieve from the read-only span.

Parameters

source
ReadOnlySpan<Byte>

A read-only span.

Returns

T

The structure retrieved from the read-only span.

Exceptions

T contains managed object references.

source is smaller than T's length in bytes.

Remarks

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

Caution

This method initializes an instance of T, including private instance fields and other implementation details, from the raw binary contents of the source span. Callers must ensure that the contents of the source span are well-formed with regard to T's internal invariants.
