问题描述

我有一个像下面这样的动态json对象,并试图用正则表达式解析它。

结果数组如{ID,1492,SourceID,AAA.A,Source,....}

 {
ID 1492
SourceID AAA.A
来源 1
SourceID 292
子项 JKLM
名称 KA PITAL YAT。
ChildName null
ListingDate 20140428
SeqNo 10000000
Average 3092,3248
SomeValue null
}



我的模式未获得null并获得,

如何处理任何建议?

我的尝试:



  string  pattern =  @  (?< = \)([^ \ s]。*?)(?= \  ; 
MatchCollection matches = Regex.Matches(item.ToString(),pattern);

解决方案

如果你坚持,试试这个:

 string pattern = @(?< = \)([^ \,]。*?)(?= \)| null; 



否则,探索将JSON解析为C#对象 [ ^ ]


这是Q& A中提到的常见问题。所以我写了一篇文章来回答这些类型的问题:在C#和amp中使用JSON ; VB [ ^ ]

I have a dynamic json objects like below and trying to parse it with regex.
result array like {ID,1492,SourceID,AAA.A,Source,....}

{
  "ID" : "1492", 
  "SourceID" : "AAA.A",  
  "Source" : 1,
  "SourceID" : "292",
  "Child" : "JKLM",
  "Name" : "KAPITAL YAT. ",
  "ChildName" : null, 
  "ListingDate" : "20140428", 
  "SeqNo" : "10000000", 
  "Average" : "3092,3248", 
  "SomeValue" : null
}


my pattern does not get "null" and get ","
How can i handle this any suggestions?

What I have tried:

 string pattern = @"(?<=\")([^\s].*?)(?=\")";
MatchCollection matches = Regex.Matches(item.ToString(), pattern);

解决方案

If you insist, try this:

string pattern = @"(?<=\"")([^\s,].*?)(?=\"")|null";


otherwise, explore Parse JSON into a C# Object[^]


This is a common question asked here in the Q&A. So I wrote an article to answer these types of questions: Working with JSON in C# & VB[^]
