我怎样才能把regex.matches到一个数组？ [英] How can i put regex.matches into an array?

问题描述

我有多个正则表达式匹配，我怎么可以把它们放到一个数组并分别打电话给他们每个例如 ID [0] ID [1]

 字符串值=（{\\ID \\：\\（[A-ZA-Z0-9 _，] +）\\）;
字符串ID = Regex.Matches（textt，@value）;`
 

解决方案

您可以做到这一点已经，因为<一href=\"http://msdn.microsoft.com/en-us/library/system.text.regularex$p$pssions.matchcollection.aspx\"><$c$c>MatchCollection有一个<一个href=\"http://msdn.microsoft.com/en-us/library/system.text.regularex$p$pssions.matchcollection.item.aspx\">int索引，让您通过索引来访问比赛。这是完全正确的：

  MatchCollection匹配= Regex.Matches（textt，@value）;
比赛firstMatch =比赛[0];
 

但如果你真的想要把比赛放到一个数组，你可以这样做：

 匹配[]匹配= Regex.Matches（textt，@value）
                       .Cast＆LT;匹配和GT;（）
                       .ToArray（）;
 

I have multiple Regex Matches, how can i put them into an array and call them each individually for example ID[0] ID[1]

string value = ("{\"ID\":\"([A-Za-z0-9_., ]+)\",");
string ID = Regex.Matches(textt, @value);`

解决方案

You can do that already, since MatchCollection has an int indexer that lets you access matches by index. This is perfectly valid:

MatchCollection matches = Regex.Matches(textt, @value);
Match firstMatch = matches[0];

But if you really want to put the matches into an array, you can do:

Match[] matches = Regex.Matches(textt, @value)
                       .Cast<Match>()
                       .ToArray();
