使用正则表达式模式并获取CS1003：C＃中的语法错误

Question

using @ but still error:

Does anyone see why this line:

String[] values = Regex.Split(line, @",(?! [\w\d\.\[\]\(\)\#\*\-_])(?=([^\"]*\"[^\"]*\")*[^\"]*$)");

Error CS1002 ; expected InsertLogtoDatabase D:\\MyProjects\\InsertLogWindowsApp\\WindowsFormsApplication1\\LogOrderi2trade.cs 119

Severity Code Description Project File Line Error CS1003 Syntax error, ',' expected InsertLogtoDatabase D:\\MyProjects\\InsertLogWindowsApp\\WindowsFormsApplication1\\LogOrderi2trade.cs 119

Answer 1

If you wanna use " with a verbatim string literal, you need to double it like ""

String[] values = Regex.Split(line, @",(?! [\w\d.[]()#*-_])(?=([^\""]\""[^\""]\"")[^\""]$)");

From C# spec $2.4.4.5 String literals :

quote-escape-sequence: ""
