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

Copies the characters in a specified substring in this instance to a Unicode character array.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)
Public Function ToCharArray ( _
	startIndex As Integer, _
	length As Integer _
) As Char()
public char[] ToCharArray(
	int startIndex,
	int length
)
public:
array<wchar_t>^ ToCharArray(
	int startIndex, 
	int length
)
member ToCharArray : 
        startIndex:int * 
        length:int -> char[] 
public function ToCharArray(
	startIndex : int, 
	length : int
) : char[]

Parameters

startIndex
Type: System..::..Int32
The starting position of a substring in this instance.
length
Type: System..::..Int32
The length of the substring in this instance.

Return Value

Type: array< System..::..Char>[]()[][]
A Unicode character array whose elements are the length number of characters in this instance starting from character position startIndex.

The startIndex parameter is zero-based. That is, the index of the first character in the string instance is zero.

If length is zero, the returned array is empty and has a zero length. If this instance is nullNothingnullptrunita null reference (Nothing in Visual Basic) or an empty string (""), the returned array is empty and has a zero length.
