C# 编程如何标记间距和“,”通过正则表达式？
我有一个 C# 程序，它接收日志字符串并尝试将其标记为各种数组。
用于示例的字符串为“Tue Oct 26 2010 23:48:54,664,macb,d/drwxrwxrwx,0,0,33-144-1,C:/WINDOWS/system32/ras”，我需要两个间距（ ' ') 和 "," 被分隔成数组。运行我的程序的结果将是这样的：
Tue Oct 26 2010 23:48:54
664
macb
d/drwxrwxrwx
0
0
33-144-1
C:/WINDOWS/system32/ras
这个结果仅部分正确，因为“，”被过滤，但空格（''）未被过滤。因此我也需要过滤掉时间 23:48:54。有人可以告诉我代码吗？谢谢！
我的代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.IO;
using System.Text.RegularExpressions;
namespace Testing
{
class Program
{
static void Main(string[] args)
{
//System.Collections.Generic.IEnumerable<String> lines = File.ReadLines
("C:\\Test\\ntfs2.txt");
String value = "Tue Oct 26 2010 23:48:54,664,macb,d/drwxrwxrwx,0,0,33-144-
1,C:/WINDOWS/system32/ras";
//
// Split the string on line breaks.
// ... The return value from Split is a string[] array.
//
String rex = @"(\t)|,";
String[] lines = Regex.Split(value, rex);
foreach (String line in lines)
{
Console.WriteLine(line);
}
}
}
}
I have a C# program which takes in a log string and tries to tokenize it into various arrays.
The string used for the example would be "Tue Oct 26 2010 23:48:54,664,macb,d/drwxrwxrwx,0,0,33-144-1,C:/WINDOWS/system32/ras" which I need both Spacing (' ') and "," to be seperated into arrays. The results from running my programs would be this:
Tue Oct 26 2010 23:48:54
664
macb
d/drwxrwxrwx
0
0
33-144-1
C:/WINDOWS/system32/ras
This result is only partially right as the "," is being filtered but not the spacing (' '). Therefore I need the time 23:48:54 to be filtered out as well. Can someone please advise me on the codes please? Thanks!
My Codes:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.IO;
using System.Text.RegularExpressions;
namespace Testing
{
class Program
{
static void Main(string[] args)
{
//System.Collections.Generic.IEnumerable<String> lines = File.ReadLines
("C:\\Test\\ntfs2.txt");
String value = "Tue Oct 26 2010 23:48:54,664,macb,d/drwxrwxrwx,0,0,33-144-
1,C:/WINDOWS/system32/ras";
//
// Split the string on line breaks.
// ... The return value from Split is a string[] array.
//
String rex = @"(\t)|,";
String[] lines = Regex.Split(value, rex);
foreach (String line in lines)
{
Console.WriteLine(line);
}
}
}
}

您可以使用
代替
正则表达式。
You can use
instead of
regular expressions.
正如 Jens 指出的，您可以只使用 String.Split 方法。然而，正则表达式将是这样的：
As Jens pointed out, you can get away with just using the String.Split method. However, the regular expression will be like this:
