关键字如下:

我该如何使用C#Regular来获取:

Hi, please help me.

"At Apr 29 2011 13:12:45 UTC,happend an earthquake(near longitude 121.98,latitude 21.18) in TAIWAN REGION,the depth is about 177km."

how do i use the c# regular to get:

time:Apr 29 2011 13:12:45 UTC

非常感谢.

Thank you very much.

^at\s+(?<time>.+?),.+?\(.+?longitude\s+(?<longitude>.+?),latitude\s+(?<latitude>.+?)\)\s+in\s+(?<location>.+?),the depth.+?\s+(?<depth>\d+)

Regex r= new Regex(
      "^at\\s+(?<time>.+?),.+?\\(.+?longitude\\s+(?<longitude>.+?),"+
      "latitude\\s+(?<latitude>.+?)\\)\\s+in\\s+(?<location>.+?),th"+
      "e depth.+?\\s+(?<depth>\\d+)",
    RegexOptions.IgnoreCase
    | RegexOptions.Compiled
    );

string message = "At Apr 29 2011 13:12:45 UTC,happend an earthquake(near longitude 121.98,latitude 21.18) in TAIWAN REGION,the depth is about 177km";

Match m = r.Match(message);

if (m.Success)
{
  Console.WriteLine("time:" + m.Groups["time"].Value);
  Console.WriteLine("longitude:" + m.Groups["longitude"].Value);
  Console.WriteLine("latitude:" + m.Groups["latitude"].Value);
  Console.WriteLine("location:" + m.Groups["location"].Value);
  Console.WriteLine("depth:" + m.Groups["depth"].Value);
}

这将为您提供如下输出:

This will give you an output like this:

time:Apr 29 2011 13:12:45 UTC
longitude:121.98
latitude 21.18
location:TAIWAN REGION
depth: 177
