.NET正則表達式來檢測和拆分字符串

Question

我想寫一個正則表達式來將下列字符串拆分成段。

#if [Customer.OrderQuantity] > 5 #then 1000 #if [Customer.OrderQuantity] < 5 #then 500 #else 100 


1st Segment: #if [Customer.OrderQuantity] > 5 #then 1000 
2nd Segment: #if [Customer.OrderQuantity] < 5 #then 500 
3rd Segment: #else 100 

您的建議非常感謝！

Answer 1

這是產生輸出你想

string source = "#if [Customer.OrderQuantity] > 5 #then 1000 #if [Customer.OrderQuantity] < 5 #then 500 #else 100"; 

string[] result = Regex.Split(source, @"\s*(?=#(?:if|else))"); 

foreach (string a in result) { 
    Console.WriteLine(a); 
} 

但我在一些點猜測，我不知道，如果這是在做你想要的其他案件。
