Answer 1

明白了，是因为前一个的逗号被匹配，导致后一个少一个逗号了
那其实改一下正则即可"rect.*?value":"218BE154127B426C96F251D325B09FDA"\}}}

Answer 2

第二个正则如下"path[^"]*":\{"from":"rect9c55044f-7312-5704-eacd-14c638f8fbc8",[^\}]*\},

Answer 3

明白了，是因为前一个的逗号被匹配，导致后一个少一个逗号了
那其实改一下正则即可"rect.*?value":"218BE154127B426C96F251D325B09FDA"\}}}这个把整个块都匹配到了。不行诶。如图

Answer 4

这样子就Ok啦~~~"rect((?!}}}).)*"218BE154127B426C96F251D325B09FDA"}}}

Answer 6

。。你好，这个匹配的是 from ，，我这个是要 匹配 to  的内容，已知道
to=  "rect98213e5a-681f-4b2c-4456-a8269d189cd0"  求所在块

Answer 7

。。你好，又碰到一个难题了，，我如果已知  红色  里面的内容，求紫色部分内容
类似的，把from改成to，后面跟上固定内容即可

Answer 8

你把下面这句：
string pattern = @"(?<=},\s*)""[^{]+{[^{}]+""rect9c55044f-7312-5704-eacd-14c638f8fbc8""[^{}]+},";
改成：
string pattern = @"(?<=},\s*)""[^{]+{[^{}]+to=  "”rect98213e5a-681f-4b2c-4456-a8269d189cd0""[^{}]+},";不就行了？

Answer 9

            MatchCollection mc = Regex.Matches(s, @"""[^,]*?,\s*?""to"":""rect44ae9ae5-b2c5-eaed-1892-2dede8217807[^,]*?,");
            foreach (Match m in mc)
            {
                Console.WriteLine(m.Value);
            }输出：
"pathe4c696f9-0ca9-077f-50cc-cf423925601d":{"from":"rect9c55044f-7312-5704-eacd-14c638f8fbc8","to":"rect44ae9ae5-b2c5-eaed-1892-2dede8217807"},

Answer 10

改一下            MatchCollection mc = Regex.Matches(s, @"""[^,]*?,[^:]*?:""rect44ae9ae5-b2c5-eaed-1892-2dede8217807[^,]*?,");
            foreach (Match m in mc)
            {
                Console.WriteLine(m.Value);
            }
输出：
"pathe4c696f9-0ca9-077f-50cc-cf423925601d":{"from":"rect9c55044f-7312-5704-eacd-14c638f8fbc8","to":"rect44ae9ae5-b2c5-eaed-1892-2dede8217807"},

Answer 11

最后正则(?<=},\s*)"[^{]+{[^{}]+"to":"rect9c55044f-7312-5704-eacd-14c638f8fbc8"谢谢各位的耐心帮忙

Answer 12

最后正则(?<=},\s*)"[^{]+{[^{}]+"to":"rect9c55044f-7312-5704-eacd-14c638f8fbc8""[^,]*?,[^:]*?:"rect44ae9ae5-b2c5-eaed-1892-2dede8217807"[^,]*?,?2个都可以感谢21楼朋友，我也试了下，少了个双引号！，还有尾巴逗号有时候出现在结尾就匹配不到。
其实我昨天就结贴过了，不知道为何失败，然后期间又发现第二个的问题，所以直接用了。100分太少了。。不好意思
