Declaration

public static readonly char[] STRING_CHAR_ARRAY

Field Value

Type	Description
char[]

Methods

CompareArray(char[], int, char[], int)

Compare two arrays starting at the specified offsets.

Declaration

public static int CompareArray(char[] larray, int lstartIndex, char[] rarray, int rstartIndex)

Parameters

Type	Name	Description
char[]	larray	left array
int	lstartIndex	start offset into larray
char[]	rarray	right array
int	rstartIndex	start offset into rarray

Returns

Type	Description
int	0 if the arrays are equal，1 if larray > rarray, -1 if larray < rarray

CompareArrayByPrefix(char[], int, char[], int)

Compare two arrays, starting at the specified offsets, but treating shortArray as a prefix to longArray. As long as shortArray is a prefix of longArray, return 0. Otherwise, behave as CompareArray(char[], int, char[], int).

Declaration

public static int CompareArrayByPrefix(char[] shortArray, int shortIndex, char[] longArray, int longIndex)

Parameters

Type	Name	Description
char[]	shortArray	prefix array
int	shortIndex	offset into shortArray
char[]	longArray	long array (word)
int	longIndex	offset into longArray

Returns

Type	Description
int	0 if shortArray is a prefix of longArray, otherwise act as CompareArray(char[], int, char[], int).
