ArrayExtensionsCastTFrom, TTo(TFrom) Method

Reinterprets the specified array by returning a CastArrayTFrom, TTo struct, so its element type is cast from TFrom to TTo. No heap allocation occurs when using this method.

C#

public static CastArray<TFrom, TTo> Cast<TFrom, TTo>(
	this TFrom[]? array
)
where TFrom : struct, new()
where TTo : struct, new()

VB

<ExtensionAttribute>
Public Shared Function Cast(Of TFrom As {Structure, New}, TTo As {Structure, New}) ( 
	array As TFrom()
) As CastArray(Of TFrom, TTo)

C++

public:
[ExtensionAttribute]
generic<typename TFrom, typename TTo>
where TFrom : value class, gcnew()
where TTo : value class, gcnew()
static CastArray<TFrom, TTo> Cast(
	array<TFrom>^ array
)

F#

[<ExtensionAttribute>]
static member Cast : 
        array : 'TFrom[] -> CastArray<'TFrom, 'TTo>  when 'TFrom : struct, new() when 'TTo : struct, new()

Parameters

array TFrom: The array to create the CastArrayTFrom, TTo from.

Type Parameters

TFrom: The actual element type of the specified array.
TTo: The reinterpreted element type after casting.

Return Value

CastArrayTFrom, TTo
A CastArrayTFrom, TTo instance for the specified array.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type TFrom. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

If the size of TTo cannot be divided by the size of TFrom, then the cast result may not cover the whole original array to prevent exceeding beyond the available buffer.
