C# 分割字符串（开发人员如何使用）

string sentence = "Hello, world! Welcome to C# programming.";
char separator = ''; // Space character
string [] words = sentence.Split(separator); // returned array

Dim sentence As String = "Hello, world! Welcome to C# programming."
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'char separator = ''; string [] words = sentence.Split(separator); ' returned array

string fruits = "apple,,banana,orange";
char separator = ',';

string [] fruitArray = fruits.Split(new char [] { separator }, StringSplitOptions.RemoveEmptyEntries); // stringsplitoptions options

Dim fruits As String = "apple,,banana,orange"
Dim separator As Char = ","c

Dim fruitArray() As String = fruits.Split(New Char () { separator }, StringSplitOptions.RemoveEmptyEntries) ' stringsplitoptions options

string fruits = "apple;banana orange";
char [] separators = { ';', ' ' };
// split string delimited
string [] fruitArray = fruits.Split(separators);

Dim fruits As String = "apple;banana orange"
Dim separators() As Char = { ";"c, " "c }
' split string delimited
Dim fruitArray() As String = fruits.Split(separators)

string longString = "one,two,three,four,five";
char separator = ',';
int maxSubstrings = 3;

string [] firstThreeItems = longString.Split(separator, maxSubstrings);

Dim longString As String = "one,two,three,four,five"
Dim separator As Char = ","c
Dim maxSubstrings As Integer = 3

Dim firstThreeItems() As String = longString.Split(separator, maxSubstrings)
