如何使用正則表達式從複雜句子中提取特定數據？

Question

我想用一個正則表達式從一個log4net文本文件中抽取複雜句子中的數據。

4012 09:47:03 INFO QueueController - method GetData(), Start = 15-3-2017 09:47:01, ElapsedSeconds = 1,9023, Task = 7514, Thread = 9 

我需要準備以下數據：

Method = GetData() 
Time = 09:47:03 
Start = 15-3-2017 09:47:01 
ElapsedSeconds = 1,9023 
Task = 7514 
Thread = 9 

我在網上搜索，但我找不到怎麼做，在這種更復雜的情況。有誰知道解決方案？

非常感謝， 的Jordy

試試這個代碼...

string text = "4012 09:47:03 INFO QueueController - method GetData(), Start = 15-3-2017 09:47:01, ElapsedSeconds = 1,9023, Task = 7514, Thread = 9"; 
Regex pattern = new Regex(@"(.*\s+)(?<Time>.*)(\s+INFO QueueController*)(.*method\s+)(?<Method>.*)(, Start\s+)(?<Start>.*)(, ElapsedSeconds =*)(.*\s+)(?<ElapsedSeconds>.*)(, Task =*)(.*\s+)(?<Task>.*)(, Thread =)(.*\s+)(?<Thread>.*)(.*)"); 
Match match = pattern.Match(text); 

string method = match.Groups["Method"].Value; 
string time = match.Groups["Time"].Value; 
string start = match.Groups["Start"].Value.Replace("=",""); 
string elapsed = match.Groups["ElapsedSeconds"].Value; 
string task = match.Groups["Task"].Value; 
string thread = match.Groups["Thread"].Value; 

Console.WriteLine("Method = " + method); 
Console.WriteLine("Time = " + time); 
Console.WriteLine("Start = " + start); 
Console.WriteLine("Elapsed = " + elapsed); 
Console.WriteLine("Task = " + task); 
Console.WriteLine("Thread = " + thread); 
Console.ReadKey(); 

這會給這樣你的輸出。
