让我很郁闷的问题！！

[CQ_alex]

string str ="1,2,3,4,5";
怎么变成
int 的1,2,3,4,5啊？
谢谢！！

C#的！

用Split函数 这个是他的用法

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) Respon……

哥们，干嘛呢？这么详细？

[mayanly]

问题都没太看明白，我也很郁闷！

[porschev]

split切开成数组。。。

再转

[hongjiaoli]

string str = "1,2,3,4,5";
string[] strList = str.Split(',');
List<int> nums = new List<int>();
for (int i = 0; i < strList.Length; i++)
{
nums.Add(int.Parse(strList[i].ToString()));
}

[打一壶酱油]

int[] idList = Convert.toint32(str.split(","));

[早安您好]

不错 学习了 。。

split好啊！我刚学那会也郁闷，用的多了，就好了！

[Quote=引用 5 楼 hrabeyond 的回复:]

using System.Linq;

string str = "1,2,3,4,5";
string[] s = str.Split(',');
int[] i = s.Select(j => Convert.ToInt32(j)).ToArray<int>();

[yuxh81]

试试：

int[] idList = str.split(",");

[guozhaoyou1]

string [] ary=str.spilt(',')
foreach(string s in ary)
{
response.write(s)
int v=int.paser(s)
}

[勤奋的阿拉丁]

string str = "1,2,3,4,5";
string[] values = str.Split(',');
List<int> results = new List<int>();
foreach (string v in values)
{
try
{
results.Add(Convert.ToInt32(v));
}
catch (Exception)
{


}

}

[手抓宝]

using System.Linq;

string str = "1,2,3,4,5";
string[] s = str.Split(',');
int[] i = s.Select(j => Convert.ToInt32(j)).ToArray<int>();

[tashiwoweiyi]

      string str = "1,2,3,4,5";
      string[] strList = str.Split(',');
      List<int> nums = new List<int>();
      for (int i = 0; i < strList.Length; i++)
      {
        nums.Add(int.Parse(strList[i].ToString()));
      }

这是最基本的东西了 这都郁闷?

用Split函数 这个是他的用法

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(','）


先多看点书吧

谢谢大伙啦！！！
