c# split函数

[lxm370832]

如果我想手动输入一些数字，用逗号隔开，然后再比较大小，用split函数可以实现吗？、如果可以把思路或者是代码打上，如果不能有没有别的办法、、

1、用字符串分隔：
using System.Text.RegularExpressions;
string str="aaajsbbbjsccc";
string[] sArray=Regex.Split(str,"js",RegexOptions.IgnoreCase);
foreach (string i in sArray) Response.Write(i.ToString() + "<br>");
输出结果：
aaa
bbb
ccc
2、用多个字符来分隔：
string str="aaajbbbscccjdddseee";
string[] sArray=str.Split(new char[2] {'j','s'});
foreach(string i in sArray) Response.Write(i.ToString() + "<br>");
输出结果：
aaa
bbb
ccc
ddd
eee
3、用单个字符来分隔：
string str="aaajbbbjccc";
string[] sArray=str.Split('j');
foreach(string i in sArray) Response.Write(i.ToString() + "<br>");
输出结果：
aaa
bbb
ccc


////////////////////////////////////////////////
string[] arr = str.Split("o");
这是一个具有语法错误的语句，Split 的 separator 参数应该是 char[] 或 string[]，不应是字符串。正确的示例：

string str = "technology";
char[] separator = { 'o' };
string[] arr = str.Split(separator);
////////////////////////////////////////////////////

String.Split 方法有6个重载函数：
程序代码
1) public string[] Split(params char[] separator)
2) public string[] Split(char[] separator, int count)
3) public string[] Split(char[] separator, StringSplitOptions options)
4) public string[] Split(string[] separator, StringSplitOptions options)
5) public string[] Split(char[] separator, int count, StringSplitOptions options)
6) public string[] Split(string[] separator, int count, StringSplitOptions options)

下边我们通过一些实例来说明下怎么使用(以下string words = "1,2.3,,4";)：
1. public string[] Split(params char[] separator)
程序代码
string[] split = words.Split(new Char[] { ',' });//返回:{"1","2.3","","4"}
string[] split = words.Split(new Char[] { ',', '.' });//返回:{"1","2","3","","4"}
2. public string[] Split(char[] separator, int count)ITPUB个人空间,n:H!C0M/S3U\u0002P
程序代码
string[] split = words.Split(new Char[] { ',', '.' }, 2);//返回:{"1","2.3,,4"}
string[] split = words.Split(new Char[] { ',', '.' }, 6);//返回:{"1","2","3","","4"}
3. public string[] Split(char[] separator, StringSplitOptions options)
程序代码
string[] split = words.Split(new Char[] { ',', '.' }, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2","3","4"} 不保留空元素
string[] split = words.Split(new Char[] { ',', '.' }, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素
4. public string[] Split(string[] separator, StringSplitOptions options)
程序代码
string[] split = words.Split(new string[] { ",", "." }, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2","3","4"} 不保留空元素
\u0002w1I+Ch%^\u0017}0string[] split = words.Split(new string[] { ",", "." }, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素
5. public string[] Split(char[] separator, int count, StringSplitOptions options)
程序代码
string[] split = words.Split(new Char[] { ',', '.' }, 2, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2.3,,4"} 不保留空元素ITPUB个人空间1K;e\u0007f\u0008f }\u0011C n
string[] split = words.Split(new Char[] { ',', '.' }, 6, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素
6. public string[] Split(string[] separator, int count, StringSplitOptions options)
程序代码
string[] split = words.Split(new string[] { ",", "." }, 2, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2.3,,4"} 不保留空元素
string[] split = words.Split(new string[] { ",", "." }, 6, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素
需要注意的是没有重载函数public string[] Split(string[] separator)，所以我们不能像VB.NET那样使用words.Split(",")，而只能使用words.Split(','）

[昵称不能为空噢噢噢噢]

string str =@"2,3,4,59,37,8"
string [] arr= str.Split(',');

int max =Int32.Parse(arr[0])
for(int i=1;i<arr.Length;i++)
{
if(max<Int32.Parse(arr[i]))
{
max=Int32.Parse(arr[i]);

}

如此这般
}

这个 看来已经有答案了

手动输入数组
string s+="输入的字符串";
string[] str=new string[]{};

str=s.split(',');

[cliu_beijing]

string[] split = words.Split(new Char[] { ',' }, 2, StringSplitOptions.RemoveEmptyEntries);//能去掉最一个空字符串

class Program
    {
        static void Main(string[] args)
        {
            string numStr = "10,8,20,56,23,40,99,120,33";
            string[] arr = numStr.Split(',');

            IntCompare compareMethod = new IntCompare();

            Array.Sort(arr, compareMethod);

            string newNumStr = "";
            for (int i = 0; i < arr.Length; i++)
            {
                newNumStr += arr[i] + ",";
            }

            Console.WriteLine(newNumStr);
            Console.ReadKey();
        }
    }

    public class IntCompare : IComparer<string>
    {
        public int Compare(string x, string y)
        {
            return int.Parse(x).CompareTo(int.Parse(y));
        }
    }

C# code
class Program
{
static void Main(string[] args)
{
string numStr = "10,8,20,56,23,40,99,120,33";
string[] arr = numStr.Split(',');
