ReadOnlySpanMarshaller<T,TUnmanagedElement> Class

Definition

Namespace:

System.Runtime.InteropServices.Marshalling

Assembly:

System.Runtime.dll

Source:

ReadOnlySpanMarshaller.cs

Important

This API is not CLS-compliant.

Supports marshalling a ReadOnlySpan<T> from managed value to a contiguous native array of the unmanaged values of the elements.

Type Parameters

T

The managed element type of the span.

TUnmanagedElement

The unmanaged type for the elements of the span.

Remarks

A ReadOnlySpan<T> marshalled with this marshaller will match the semantics of GetReference<T>(ReadOnlySpan<T>). In particular, this marshaller will pass a non-null value for a zero-length span if the span was constructed with a non-null value.
