Creates a new Span<T> object over the entirety of a specified array.
public:
Span(cli::array <T> ^ array);public Span(T[]? array);public Span(T[] array);new Span<'T> : 'T[] -> Span<'T>Public Sub New (array As T())Parameters
- array
- T[]
The array from which to create the Span<T> object.
Exceptions
T is a reference type, and array is not an array of type T.
Remarks
If array is null, this constructor returns a null Span<T>.

Important
This API is not CLS-compliant.
Creates a new Span<T> object from a specified number of T elements starting at a specified memory address.
public:
Span(void* pointer, int length);[System.CLSCompliant(false)]
public Span(void* pointer, int length);[<System.CLSCompliant(false)>]
new Span<'T> : nativeptr<unit> * int -> Span<'T>Parameters
- pointer
- Void*
A pointer to the starting address of a specified number of T elements in memory.
- Attributes
Exceptions
T is a reference type or contains pointers and therefore cannot be stored in unmanaged memory.
length is negative.
Remarks
This constructor should be used with care, since it creates arbitrarily typed Ts from a void*-typed block of memory, and neither pointer nor length are validated by the constructor.

Creates a new Span<T> object that includes a specified number of elements of an array starting at a specified index.
public:
Span(cli::array <T> ^ array, int start, int length);public Span(T[]? array, int start, int length);public Span(T[] array, int start, int length);new Span<'T> : 'T[] * int * int -> Span<'T>Public Sub New (array As T(), start As Integer, length As Integer)Parameters
- array
- T[]
The source array.
Exceptions
array is null, but start or length is non-zero.
-or-
start is outside the bounds of the array.
-or-
start and length exceeds the number of elements in the array.
T is a reference type, and array is not an array of type T.
Remarks
This method returns default when array is null.
