【问题描述】：

这是我的字符串，我在拆分为字符串数组时遇到问题，键的逗号分隔值

{ 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 "Ucomment = tet","tet1" 作为单独的数组。但是当用逗号分隔时我需要拆分字符串[]

UComment = tet,tet1 OComment = test,test1

我尝试过使用正则表达式 ,(?=([^\"]\"[^\"]\")[^\"]$) " 但它没有用。

您的预期输出在这里是什么样的？
@tim-biegeleisen，它是 sring 数组，它会像 "Yr = 2019", "Mth = DECEMBER", "SeqN = 0", "UComment = tet,tet1"

【解决方案1】：

您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);
}

打印出来：

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

这里是使用的正则表达式模式的解释：

\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 OR
                           is the end of the input
