string str = "帥哥,TXT,03/12/2009,13:22:19,4,111,192.192.192.192,"; string[] strArray = str.Split(','); Response.Write(strArray[0] + "<br>"); Response.Write(strArray[3] + "<br>"); Response.Write(strArray[6] + "<br>");

如果我要用上面的code然後去取出
"帥哥","TXT",03/12/2009,13:22:19,4,"111",192.192.192.192,
該怎麼去做修改

string a = "\"帥哥\",\"TXT\",03/12/2009,13:22:19,4,\"111\",192.192.192.192,"; string reg = "^\"(?<chinese>.[^a-z]).+(?<time>\\d{2}:\\d{2}:\\d{2}).+(?<ip>\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3})"; string[] strArray = a.Split(','); foreach (Match item in Regex.Matches(a, reg)) { Response.Write("這是中文：" + item.Groups["chinese"].Value + "<br/>"); Response.Write("這是時間：" + item.Groups["time"].Value + "<br/>"); Response.Write("這是IP：" + item.Groups["ip"].Value + "<br/>"); }
這是利用正規表示式來抓的
不過我參數寫的很鳥，還可以再優化^^

馬上來修正....
^"(?<chinese>.[^a-z]).+(?<time>\d{2}:\d{2}:\d{2}).+?(?<ip>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})

public partial class CountOnLineMember : System.Web.UI.Page { StringBuilder txtSB; System.Collections.Hashtable MemberCount_h = new System.Collections.Hashtable(); string LoggerPath = ConfigurationSettings.AppSettings["LoggerFilePath"]; string OutLoggerPath = ConfigurationSettings.AppSettings["OutLoggerFilePath"]; /* 下面是我txt檔的資料，每一行都是這樣個樣 "test","RAS",日期,13:35:57,4,"名字",,,"IP",,"192.168.2.32",,"192.168.2.202",128,,"192.168.2.202",,1236836157,,5,,1,2,,,0,"311 1 192.168.2.202 03/11/2009 06:42:23 9",,,,,1,,,,"1894",3,,,,,"17",1,,1,1,"122.116.69.181",,,,,,,,"MSRASV5.20",311,,"0x0053554E504C5553",4,,"Use Windows authentication for all users",,,,"MSRAS-0-RALF-PC-Q6600","MSRASV5.20" */ protected void Page_Load(object sender, EventArgs e) { string fName = ""; try { //Delete Temp.txt fName = OutLoggerPath + "Temp.txt"; string fPath = Path.GetFullPath(fName); FileInfo fileInfo = new FileInfo(fPath); fileInfo.Delete(); //Copy Log to Temp.txt txtSB = new StringBuilder(); //Get yesterday data fName = LoggerPath + "IN" + DateYear.Now.ToString("yyMMdd") + ".log"; //取得完整檔名及路徑 fPath = Path.GetFullPath(fName); //傳回絕對路徑 fileInfo = new FileInfo(fPath); fileInfo.CopyTo(OutLoggerPath + "Temp.txt"); AppendTodayData(); fName = OutLoggerPath + "Temp.txt"; fPath = Path.GetFullPath(fName); fileInfo = new FileInfo(fPath); FileStream fs = fileInfo.Open(FileMode.Open,FileAccess.Read); StreamReader sr = new StreamReader(fs, System.Text.Encoding.Default); if (fs.Length > 0) do { string srReadLine = sr.ReadLine(); txtSB.Append(srReadLine + "\r\n"); MainTainStringLine(srReadLine); } while (sr.Peek() != -1); fs.Close(); DataTable dt = new DataTable(); dt.Columns.Add(new DataColumn("Resource", typeof(string))); dt.Columns.Add(new DataColumn("Time", typeof(string))); dt.Columns.Add(new DataColumn("IP", typeof(string))); dt.Columns.Add(new DataColumn("ID", typeof(string))); dt.Columns.Add(new DataColumn("User", typeof(string)));

要怎麼改成讀出名字、IP、日期

ip有一堆 你要抓的是哪一個ip?
依據是啥?

"test","RAS",日期,13:35:57,4,"名字",,,"IP",,"192.168.2.32",,"192.168.2.202",128,,"192.168.2.202",,1236836157,,5,,1,2,,,0,"311 1 192.168.2.202 03/11/2009 06:42:23 9",,,,,1,,,,"1894",3,,,,,"17",1,,1,1,"122.116.69.181",,,,,,,,"MSRASV5.20",311,,"0x0053554E504C5553",4,,"Use Windows authentication for all users",,,,"MSRAS-0-RALF-PC-Q6600","MSRASV5.20"
我要抓有寫「IP」二個字的資料，因該是抓「,」第五個的資料

如#1所寫,用split()將字串切成array後,就可以取得某段的值,應該是可行的,不知您有沒有試過

看你的需求是註定要split後算位置抓資料了=.=

陣列我不太會用能否教一下該如何修改

split的相關說明可以google一下,我找了幾篇,您參考一下
