Regex.Match簡單數組

這是我正在使用的。Regex.Match簡單數組

{"allCharacters":[{"id":"410199","name":"D4rkness1939pwnz","gender":"1","skipLevel":"1","role":"alt","level":"30","generation":"1","xp":"4420578","gold":"2593","xpNextLevel":8735843},{"id":"250004","name":"Fallen_Sir_Illuminati","gender":"0","skipLevel":"0","role":"alt","level":"1","generation":"1","xp":"0","gold":"100","xpNextLevel":3000},{"id":"402615","name":"PRO_Illuminati","gender":"0","skipLevel":"0","role":"alt","level":"1","generation":"1","xp":"0","gold":"100","xpNextLevel":3000},{"id":"146314","name":"PRO_Illuminati_BRD","gender":"1","skipLevel":"0","role":"main","level":"25","generation":"17","xp":"1897767","gold":"375492","xpNextLevel":1929158},{"id":"342584","name":"PRO_Sir_Illuminati","gender":"0","skipLevel":"0","role":"alt","level":"1","generation":"1","xp":"2000","gold":"200","xpNextLevel":3000},{"id":"252818","name":"Sir_Ashton_of_Illuminati","gender":"0","skipLevel":"0","role":"alt","level":"1","generation":"1","xp":"2000","gold":"200","xpNextLevel":3000},{"id":"336515","name":"Sir_Illuminati","gender":"0","skipLevel":"0","role":"alt","level":"1","generation":"1","xp":"0","gold":"100","xpNextLevel":3000}],"currentCharacter":0}

我試圖得到一個PRO_Illuminati_BRD，與角色「：」主要部分是正則表達式匹配的最具體的部分。所以基本上這條線具體。

{"id":"146314","name":"PRO_Illuminati_BRD","gender":"1","skipLevel":"0","role":"main","level":"25","generation":"17","xp":"1897767","gold":"375492","xpNextLevel":1929158},

下面都是我已經使用了Regex.Match，但他們對D4rkness1939pwnz都只匹配。

Match RealMain = Regex.Match(RawRes, "\"id\":\"(.*?)\",\"name\":\"(.*?)\",\"gender\":\"[0-9]\",\"skipLevel\":\"0\",\"role\":\"main\"");

和

Match RealMain = Regex.Match(RawRes, "\"id\":\"(.*?)\",\"name\":\"(.*?)\",\"gender\":\"(.*?)\",\"skipLevel\":\"0\",\"role\":\"main\"");

和

Match RealMain = Regex.Match(RawRes, "\"id\":\"(.*?)\",\"name\":\"(.*?)\",\"gender\":\"[0-9]\",\"skipLevel\":\"0\",\"role\":\"main\",\"level\":\"(.*?)\",\"generation\":\"(.*?)\",\"xp\":\"(.*?)\",\"gold\":\"(.*?)\",\"xpNextLevel\"");

和

Match RealMain = Regex.Match(RawRes, "\"id\":\"(.*?)\",\"name\":\"(.*?)\",\"gender\":\"(.*?)\",\"skipLevel\":\"0\",\"role\":\"main\",\"level\":\"(.*?)\",\"generation\":\"(.*?)\",\"xp\":\"(.*?)\",\"gold\":\"(.*?)\",\"xpNextLevel\"");

，但他們總是返回D4rkness1939pwnz之一。：S

我哪裏錯了？

這看起來像JSON給我。爲什麼不使用JSON解析器，如[JSON.NET]（http://json.net）？ – Adam

我只是想用正則表達式來抓住那條線，你能幫忙嗎？ –

我不擅長正則表達式。我強烈建議使用諸如[Regex Tester]（http://regexpal.com/）之類的工具來幫助找到正確的表達式。 – Adam

你所面臨的問題是，你只讀了第一場比賽。

要遍歷你應該使用相匹配的所有比賽：

MatchCollection matches = Regex.Matches(RawRes, "\"id\":\"(.*?)\",\"name\":\"(.*?)\",\"gender\":\"[0-9]\",\"skipLevel\":\"0\",\"role\":\"main\""); 
foreach(Match item in matches) 
{ 
    if (item.Groups[2].Value == "PRO_Illuminati_BRD") 
     return item; 
}

另外，您應該將正則表達式改變這樣的事情：

Regex.Matches(RawRes, "^.*\"id\":\"(.*?)\",\"name\":\"PRO_Illuminati_BRD\",\"gender\":\"[0-9]\",\"skipLevel\":\"0\",\"role\":\"main\"");

這回答了你的問題，但我建議你如果您需要更多項目而不僅僅是單個項目，請使用其他人已經描述的JSON解析器。

當我使用時，MatchCollection匹配= Regex.Matches（RawRes，「\」id \「：\」[0-9] {1,20 } \」，\ 「名稱\」：\ 「\」 \ 「性別\（*？）」：\ 「[0-9] {1} \」，\ 「skipLevel \」：\ 「0 \」，「角色」：\「main」）; 這場比賽在比賽中獲得了所有這些廢話[0] .ToString（）; –

如何使用json parser，而不是正則表達式

string json = @"{""allCharacters"":[{""id"":""410199"",""name"":""D4rkness1939pwnz"",""gender"":""1"",""skipLevel"":""1"",""role"":""alt"",""level"":""30"",""generation"":""1"",""xp"":""4420578"",""gold"":""2593"",""xpNextLevel"":8735843},{""id"":""250004"",""name"":""Fallen_Sir_Illuminati"",""gender"":""0"",""skipLevel"":""0"",""role"":""alt"",""level"":""1"",""generation"":""1"",""xp"":""0"",""gold"":""100"",""xpNextLevel"":3000},{""id"":""402615"",""name"":""PRO_Illuminati"",""gender"":""0"",""skipLevel"":""0"",""role"":""alt"",""level"":""1"",""generation"":""1"",""xp"":""0"",""gold"":""100"",""xpNextLevel"":3000},{""id"":""146314"",""name"":""PRO_Illuminati_BRD"",""gender"":""1"",""skipLevel"":""0"",""role"":""main"",""level"":""25"",""generation"":""17"",""xp"":""1897767"",""gold"":""375492"",""xpNextLevel"":1929158},{""id"":""342584"",""name"":""PRO_Sir_Illuminati"",""gender"":""0"",""skipLevel"":""0"",""role"":""alt"",""level"":""1"",""generation"":""1"",""xp"":""2000"",""gold"":""200"",""xpNextLevel"":3000},{""id"":""252818"",""name"":""Sir_Ashton_of_Illuminati"",""gender"":""0"",""skipLevel"":""0"",""role"":""alt"",""level"":""1"",""generation"":""1"",""xp"":""2000"",""gold"":""200"",""xpNextLevel"":3000},{""id"":""336515"",""name"":""Sir_Illuminati"",""gender"":""0"",""skipLevel"":""0"",""role"":""alt"",""level"":""1"",""generation"":""1"",""xp"":""0"",""gold"":""100"",""xpNextLevel"":3000}],""currentCharacter"":0}"; 
var obj = new JavaScriptSerializer().Deserialize<Root>(json); 

//var character = obj.allCharacters.First(i => i.name == "PRO_Illuminati_BRD"); 
var character = obj.allCharacters.First(i => i.role == "main");

我將使用什麼參考C＃.net 4.0窗體？看起來很棒。 –

@AshtonSchultz [System.Web.Script.Serialization]（http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx） –

我發現它：D命名空間：System .Web.Script.Serialization 程序集：System.Web.Extensions（在System.Web.Extensions.dll中） –
