Definition

Namespace:

System.Runtime.CompilerServices

Assembly:

System.Runtime.dll

Source:

RuntimeHelpers.cs

Provides a fast way to access constant data stored in a module as a ReadOnlySpan<T>.

public:
generic <typename T>
 static ReadOnlySpan<T> CreateSpan(RuntimeFieldHandle fldHandle);

public static ReadOnlySpan<T> CreateSpan<T> (RuntimeFieldHandle fldHandle);

static member CreateSpan : RuntimeFieldHandle -> ReadOnlySpan<'T>

Public Shared Function CreateSpan(Of T) (fldHandle As RuntimeFieldHandle) As ReadOnlySpan(Of T)

Type Parameters

T

The type of the ReadOnlySpan data.

Parameters

fldHandle

RuntimeFieldHandle

A field handle that specifies the location of the data to be referred to by the ReadOnlySpan<T>. The Rva of the field must be aligned on a natural boundary of T.

Returns

ReadOnlySpan<T>

The data stored in the field.

Exceptions

ArgumentException

fldHandle refers to a field that's not an Rva or is misaligned, or T is of an invalid type.

Remarks

This method is intended for compiler use rather than use directly in code. T must be one of byte, sbyte, char, short, ushort, int, long, ulong, float, or double.
