校正跨語言

正則表達式模式我發現這個正則表達式模式在http://gskinner.com/RegExr/校正跨語言

,(?=(?:[^"]*"[^"]*")*(?![^"]*"))

哪個模式匹配CSV分隔的值（更具體而言，分離逗號，可以在被分割），其在該網站上的作品與我的測試數據非常好。您可以在測試時看到我認爲是站點底部面板中的JavaScript實現。

但是，當我嘗試在C＃/ .net中實現這一點時，匹配不能正常工作。我的實現：

Regex r = new Regex(",(?=(?:[^\"]*\"[^\"]*\")*(?![^\"]*\"))", RegexOptions.ECMAScript); 
//get data... 
foreach (string match in r.Split(sr.ReadLine())) 
{ 
    //lblDev.Text = lblDev.Text + match + "<br><br><br><p>column:</p><br>"; 
    dtF.Columns.Add(match); 
} 

//more of the same to get rows

在某些數據行的結果上面的網站上所產生的結果完全一致，但在其他的頭6點左右的行失敗分裂或根本不存在分割陣列英寸

任何人都可以告訴我，爲什麼模式似乎不以相同的方式表現？

你的意思是前六行還是前六列？如果行;那麼你需要看看'sr.ReadLine（）'和圍繞它的循環，以確保你正在正確讀取數據。也;我注意到，您的測試數據在第二個數據行的產品描述列的中間包含一個換行符。換行符會影響你的結果。 – 2013-05-08 10:36:06
