英文:
Split into string array only the key by comma and not values c#
问题
这是我的字符串，当我尝试使用逗号分隔键的字符串数组时，出现问题。
> { Yr = 2019, Mth = DECEMBER , SeqN = 0, UComment = tet,tet1, OComment = test,test1, FWkMth = WK, FSafety = Y, FCustConsign = Y, FNCNRPull = 0, FNCNRPush = 0, CreatedTime = 2020-01-03 06:16:53 }
当我尝试使用 string.Split(',') 时，我得到了 "Ucomment = tet","tet1" 作为单独的数组。
但我需要在逗号分隔时得到分割的字符串数组。
> UComment = tet,tet1
> OComment = test,test1
我尝试使用正则表达式 ,(?=([^"]"[^"]")[^"]$)"，但它没有起作用。
英文:
This is my String and i have problems when splitting into string array with comma seperated values for keys
> { Yr = 2019, Mth = DECEMBER , SeqN = 0, UComment = tet,tet1, OComment = test,test1, FWkMth = WK, FSafety = Y, FCustConsign = Y, FNCNRPull = 0, FNCNRPush = 0, CreatedTime = 2020-01-03 06:16:53 }
when i try to use string.Split(',') i get "Ucomment = tet","tet1" as seperate array.
But i need to have split string[] when seperated by comma
> UComment = tet,tet1
> OComment = test,test1
I have tried using the regex ,(?=([^"]"[^"]")[^"]$)" but it didnot work.

以下是已翻译的内容：
你可以尝试匹配正则表达式模式\S+\s*=\s*.*?(?=\s*,\s*\S+\s*=|\s*\}$)：
string input = "{ Yr = 2019, Mth = DECEMBER , SeqN = 0, UComment = tet,tet1, OComment = test,test1, FWkMth = WK, FSafety = Y, FCustConsign = Y, FNCNRPull = 0, FNCNRPush = 0, CreatedTime = 2020-01-03 06:16:53 }";Regex regex = new Regex(@"\S+\s*=\s*.*?(?=\s*,\s*\S+\s*=|\s*\}$)");var results = regex.Matches(input);foreach (Match match in results){Console.WriteLine(match.Groups[0].Value);}
这将打印：
Yr = 2019Mth = DECEMBERSeqN = 0UComment = tet,tet1OComment = test,test1FWkMth = WKFSafety = YFCustConsign = YFNCNRPull = 0FNCNRPush = 0CreatedTime = 2020-01-03 06:16:53
以下是正则表达式模式的解释：
\S+：匹配一个键（非空白字符的序列）。\s*：匹配可选的空格。=：匹配等号。.*?：匹配任何字符，直到看到下一个键/值对的开始或输入的结束。(?=\s*,\s*\S+\s*=|\s*\}$)：这部分是一个正向预查，它要求接下来的内容要么是下一个键/值对的开始，要么是输入的结束。
英文:
You may try matching on the regex pattern \S+\s*=\s*.*?(?=\s*,\s*\S+\s*=|\s*\}$):
string input = "{ Yr = 2019, Mth = DECEMBER , SeqN = 0, UComment = tet,tet1, OComment = test,test1, FWkMth = WK, FSafety = Y, FCustConsign = Y, FNCNRPull = 0, FNCNRPush = 0, CreatedTime = 2020-01-03 06:16:53 }";Regex regex = new Regex(@"\S+\s*=\s*.*?(?=\s*,\s*\S+\s*=|\s*\}$)");var results = regex.Matches(input);foreach (Match match in results){Console.WriteLine(match.Groups[0].Value);}
This prints:
Yr = 2019Mth = DECEMBERSeqN = 0UComment = tet,tet1OComment = test,test1FWkMth = WKFSafety = YFCustConsign = YFNCNRPull = 0FNCNRPush = 0CreatedTime = 2020-01-03 06:16:53
Here is an explanation of the regex pattern used:
\S+ match a key\s* followed by optional whitespace and= literal '='\s* more optional whitespace.*? match anything until seeing(?=\s*,\s*\S+\s*=|\s*\}$) that what follows is either the start of the next key/value ORis the end of the input
