使用RestSharp到deserialise JSON阵列

Question

我也正在从超出了我的控制API调用返回了以下JSON对象：

{ 
    "GetBusinessGroupsRestResult": [ 
    { 
    "BgId": 1, 
    "NodeLevel": 1, 
    "BusinessDescription": "Business Groups", 
    "BusinessName": "Root", 
    "nodegroupid": 2, 
    "nodegroupname": "Root", 
    "nodegroupdesc": "Root", 
    "sorkkey": "Root", 
    "Marked": 2 
    }, 
    { 
    "BgId": 2, 
    "NodeLevel": 2, 
    "BusinessDescription": "Business A", 
    "BusinessName": "Business A", 
    "ParentID": 1, 
    "nodegroupid": 3, 
    "nodegroupname": "Business A", 
    "nodegroupdesc": "Business A", 
    "sorkkey": "Business A", 
    "Marked": 2 
    }, 
    ... 
] 
} 

我已经在尝试将其deserialise到C＃对象实例创建以下类的结构：

public class GetBusinessGroupsRestResult 
{ 
    public List<BusinessGroup> BusinessGroups { get; set; } 
} 

public class BusinessGroup 
{ 
    [DeserializeAs(Name = "BgId")] 
    public int BusinessGroupId { get; set; } 

    public int NodeLevel { get; set; } 
    public string BusinessDescription { get; set; } 
    public string BusinessName { get; set; } 

    [DeserializeAs(Name = "ParentID")] 
    public int ParentId { get; set; } 

    [DeserializeAs(Name = "nodegroupid")] 
    public int NodeGroupId { get; set; } 

    [DeserializeAs(Name = "nodegroupname")] 
    public string NodeGroupName { get; set; } 

    [DeserializeAs(Name = "sorkkey")] 
    public string SortKey { get; set; } 

    public int Marked { get; set; } 
} 

我想它使用RestSharp，指定rootElement的为GetBusinessGroupsRestResult到deserialise。当尝试使用RestSharp的IRestResponse<T> Execute<T>(RestRequest)，我收到以下错误deserialisation：

System.InvalidCastException: Unable to cast object of type 'RestSharp.JsonArray' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'. 

我已经成功地从deserialise此API不返回之前列出的反应，例如：

{ 
    "AcquireSecurityTokenRestResult": { 
    "SecurityToken": "SECURITY-TOKEN", 
    "SessionLength": 600000, 
    "APIVersion": "VERSION" 
    } 
} 

随着以下POCO：

public class AcquireSecurityTokenRestResult 
{ 
    public string SecurityToken { get; set; } 
    public int SessionLength { get; set; } 
    [DeserializeAs(Name = "APIVersion")] 
    public string ApiVersion { get; set; } 
} 

任何人都可以在正确的方向指向我吗？谢谢！

管理使其工作。该Execute部分：

var client = new RestClient("http://localhost:3000/"); 
var request = new RestRequest("main", Method.GET); 
var response = client.Execute<RootObject>(request); 

及其类别：

public class RootObject 
{ 
    public List<BusinessGroup> GetBusinessGroupsRestResult { get; set; } 
} 

public class BusinessGroup 
{ 
    [DeserializeAs(Name = "BgId")] 
    public int BusinessGroupId { get; set; } 

    public int NodeLevel { get; set; } 
    public string BusinessDescription { get; set; } 
    public string BusinessName { get; set; } 

    [DeserializeAs(Name = "ParentID")] 
    public int ParentId { get; set; } 

    [DeserializeAs(Name = "nodegroupid")] 
    public int NodeGroupId { get; set; } 

    [DeserializeAs(Name = "nodegroupname")] 
    public string NodeGroupName { get; set; } 

    [DeserializeAs(Name = "nodegroupdesc")] 
    public string NodeGroupDesc { get; set; } 

    [DeserializeAs(Name = "sorkkey")] 
    public string SortKey { get; set; } 

    public int Marked { get; set; } 
} 

由于主要反应是包含数组称为GetBusinessGroupsRestResult一个对象，你需要在你的根对象为好。

基本上可以通过在GetBusinessGroupsRestResult类中添加一个DeserializeAs属性来BusinessGroups物业解决您的例子：

public class GetBusinessGroupsRestResult 
{ 
    [DeserializeAs(Name = "GetBusinessGroupsRestResult")] 
    public List<BusinessGroup> BusinessGroups { get; set; } 
}

超过一个答案，忠告。为什么不使用Json.NET，而不是使用RESTSharp？

我碰到了RESTSharp的问题，这个问题在Json.NET中非常有效。
