String Constructor (SByte*, Int32, Int32, Encoding)

 

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, a length, and an Encoding object.

This API is not CLS-compliant.

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

        enc:Encoding -> String

Parameters

value
Type: System.SByte*

A pointer to an array of 8-bit signed integers.

startIndex
Type: System.Int32

The starting position within value.

length
Type: System.Int32

The number of characters within value to use.

enc
Type: System.Text.Encoding

An object that specifies how the array referenced by value is encoded. If enc is null, ANSI encoding is assumed.

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 as specified by enc.

AccessViolationException

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