Initializes a new instance of the String class to the value indicated by a specified pointer to an array of 8-bit signed integers, a starting position within that array, and a length.

This API is not CLS-compliant.

Visual Basic does not support APIs that consume or return unsafe types.

Parameters

value
Type:

A pointer to an array of 8-bit signed integers. The integers are interpreted using the current system code page encoding (that is, the encoding specified by ).

startIndex
Type:

The starting position within value.

length
Type:

The number of characters within value to use.

Exception Condition
ArgumentNullException

value is null.

ArgumentOutOfRangeException

startIndex or length is less than zero.

-or-

The address specified by value + startIndex is too large for the current platform; that is, the address calculation overflowed.

-or-

The length of the new string to initialize is too large to allocate.

ArgumentException

The address specified by value + startIndex is less than 64K.

-or-

A new instance of String could not be initialized using value, assuming value is encoded in ANSI.

AccessViolationException

value, startIndex, and length collectively specify an invalid address.
