CreateInstance Method

2013-01-16

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Creates a one-dimensional Array of the specified Type and length, with zero-based indexing.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Shared Function CreateInstance ( _
    elementType As Type, _
    length As Integer _
) As Array

public static Array CreateInstance(
    Type elementType,
    int length
)

public:
static Array^ CreateInstance(
    Type^ elementType, 
    int length
)

static member CreateInstance : 
        elementType:Type * 
        length:int -> Array

public static function CreateInstance(
    elementType : Type, 
    length : int
) : Array

Parameters

elementType
Type: System. . :: . .Type
The Type of the Array to create.

length
Type: System. . :: . .Int32
The size of the Array to create.

Return Value

Type: System. . :: . .Array
A new one-dimensional Array of the specified Type with the specified length, using zero-based indexing.

Exceptions

Exception	Condition
ArgumentNullException	elementType is null Nothing nullptr unit a null reference (Nothing in Visual Basic) .
ArgumentException	elementType is not a valid Type.
NotSupportedException	elementType is not supported. For example, Void is not supported. -or- elementType is an open generic type.
ArgumentOutOfRangeException	length is less than zero.

Remarks

Unlike most classes, Array provides the CreateInstance method, instead of public constructors, to allow for late bound access.

Reference-type elements are initialized to null Nothing nullptr unit a null reference (Nothing in Visual Basic) . Value-type elements are initialized to zero.

This method is an O(n) operation, where n is length.

.NET Framework Security

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see dd66cd4c-b087-415f-9c3e-94e3a1835f74.
