string 返回数组问题

Question

string[] strArray = http.Split(new char[] { ',' });
  bean.url = strArray[1];
 lst.Add(bean);
 this.SetDataGrid(lst);
 this._urlList = lst;读取的文件格式是
1,需要的字符串
2,需要的字符串标红代码部分跟踪获取到的数组是"1""需要的字符串/r/n2" "需要的字符串/r/n3"而lst.Add(bean)
中只获取到
"需要的字符串/r/n2"
这一条数据 帮帮忙吧

Answer 1

string[] strArray = http.Split(','); 
foreach (string bean in strArray)
{
  lst.Add(bean); 
}

Answer 2

string[] strArray = http.Split(new string[] { ",","/r/n" }); 

Answer 3

少了个参数
string[] strArray = http.Split(new string[] { ",","/r/n" },StringSplitOptions.None); 

Answer 4

string[] strArray = http.Split(",","\r\n"); 

Answer 5

无法将类型“string”隐式转换为“char”

Answer 6

string[] strArray = System.Text.RegularExpressions.Regex.Split(http, @",|\r\n"); 

Answer 7

string[] strArray = System.Text.RegularExpressions.Regex.Split(http, @"/r/n\d,"); 

Answer 8

写个正则吧
System.Text.RegularExpressions.Regex.Split(http, @"/r/n\d,"); 
很好很强大

Answer 9

而lst.Add(bean) 
中只获取到 
"需要的字符串/r/n2" 
这一条数据 
5555各位大侠忽略了这个原本是while (xxx.Peek() >= 0)本地打开文件命令可以读取下一个字符而不使用他~~~~
string  我找不到方法搞定先谢谢wuyi8808 至少能循环了，你的两次回帖相当牛逼~~~啊哦 可是 我的lst.Add(bean)只能读到第一条数据，后面的就读取不到了

Answer 10

 ArrayList lst = new ArrayList();
                    urlBean bean = new urlBean();
                    string[] strArray = System.Text.RegularExpressions.Regex.Split(http,"\r\n");
                   
                    foreach (string i in strArray)
                        {
                            //this.dataGridView1["url", strArray.Length].Value = strArray.ToString();
                            bean.url = strArray[0].ToString();
                            //this.tishikuang.AppendText(strArray[0].ToString() + "\r\n");
                            lst.Add(bean);
                            this.SetDataGrid(lst);
                            this._urlList = lst;
                        }
                            this.tishikuang.AppendText("数据读取成功！\r\n");数据为
1234567
7654321
0000000
时
循环三次 读取出了第一条数据………………

Answer 12

Answer 13

0000000这既是我的实际文本原本想用,分割，但看了一些人的回复 发现可以直接用回车分割所以改了一点但是这样dataGridView1的url 只能循环输出第一条也就是 1234567

Answer 14

bean.url = strArray[0].ToString(); 把0改成i

Answer 15

谢谢楼上的兄弟回复郁闷ing改成i出错

Answer 16

看错了..
这里应该是:                  
                    foreach (string s in strArray) //把i改成s把,看着顺眼一些.
                        {                             bean.url = s;
                            lst.Add(bean); 
                            this.SetDataGrid(lst); 
                            this._urlList = lst; 
                        }
