C#的split（）函数的用法（原创）--王超C#

split（）函数是用来分隔一个字符串变成一个字符串数组：

1.用空格分隔字符串：（单个字符分隔）

string a = "i am a person";
            string[] b;
            b = a.Split(' ');
            foreach (string k in b)
            {
                Console.WriteLine(k);

            }

            Console.ReadKey();

2.多个字符分隔：用char数组

string a = "ixyamyaxperson";
            
            char[] c = {'x','y'};

            string[] b;
            
            b=a.Split(c);

            foreach (string k in b)
            {
                Console.WriteLine(k);

            }

            Console.ReadKey();

3.单个字符串分隔：

string a = "ixyamxyaxyperson";

            string[] c = {"xy"};

            string[] b;

            b = a.Split(c,StringSplitOptions.None);

            foreach (string k in b)
            {
                Console.WriteLine(k);

            }

            Console.ReadKey();

4.多个字符串：

string a = "ixyamxyhhaxyperson";

            string[] c = {"xy","hh"};

            string[] b;

            b = a.Split(c,StringSplitOptions.RemoveEmptyEntries);

            foreach (string k in b)
            {
                Console.WriteLine(k);

            }

            Console.ReadKey();

5.指定分成几部分：

string a = "ixybhhamxyhhaxyperson";

            string[] c = {"xy","hh"};

            string[] b;

            b = a.Split(c,2,StringSplitOptions.RemoveEmptyEntries);

            foreach (string k in b)
            {
                Console.WriteLine(k);

            }

            Console.ReadKey();
