我想能夠使用c＃提取所有數據點sin下面的json。我需要所有StandardId的所有值。不只是一個單一的數據點，而是所有實例StandardIdc＃挑出數據表json

{ 
    "CreatedBy": null, 
    "CanBeRemoved": false, 
    "ConfigurationItems": [ "" ], 
    "ApprovalReasons": [ 
    { 
     "AssociatedCI": "", 
     "AssociatedRuleName": "BRS: ", 
     "AssociatedRuleApprovalType": null, 
     "AssociatedRulePartyType": "Group", 
     "AssociatedRulePartyName": "Digital ", 
     "AssociatedAdditionalComment": "Added to all " 
    } 
    ], 
    "PossibleApprovers": [ 
    { 
     "Approver": { 
     "Display": "Jag", 
     "StandardId": "I6", 
     "RoleName": null, 
     "FullName": null, 
     "LineOfBusiness": null, 
     "ErrorMessage": null 
     },

反序列化爲一個對象，然後只需訪問屬性 – maccettura

是，如何？我從來沒有使用json – kacalapy

可能的重複[如何解析JSON與C＃？]（https://stackoverflow.com/questions/6620165/how-can-i-parse-json-with-c） – NtFreX

最簡單的方法是通過@maccettura的一個份額。

創建一個C＃對象

打開json2csharp一個生成的類。 Visual Studio可以生成其對你太：

Foo foo = JsonConvert.DeserializeObject<Foo>(json);
