RestSharp：ItemChoice始终为null(RestSharp: ItemChoice always null)
我是RestSharp的新手，并尝试通过subsonic -api访问我的亚音速服务器。 包含在亚音速响应标签中的每个响应，例如
<subsonic-response xmlns="http://subsonic.org/restapi" status="ok" version="1.10.1"> <artists ignoredArticles="The El La Los Las Le Les"> <index name="A"> <artist id="5449" name="A-Ha" coverArt="ar-5449" albumCount="4"/> <artist id="5421" name="ABBA" coverArt="ar-5421" albumCount="6"/> <artist id="5432" name="AC/DC" coverArt="ar-5432" albumCount="15"/> <artist id="6633" name="Aaron Neville" coverArt="ar-6633" albumCount="1"/> </index> <index name="B"> <artist id="5950" name="Bob Marley" coverArt="ar-5950" albumCount="8"/> <artist id="5957" name="Bruce Dickinson" coverArt="ar-5957" albumCount="2"/> </index> </artists>Xsd为序列化生成了以下类：
public partial class Response { private object itemField; private ItemChoiceType itemElementNameField; private ResponseStatus statusField; private string versionField; [System.Xml.Serialization.XmlChoiceIdentifierAttribute("ItemElementName")] public object Item { get { return this.itemField; } set { this.itemField = value; } } [System.Xml.Serialization.XmlIgnoreAttribute()] public ItemChoiceType ItemElementName { get { return this.itemElementNameField; } set { this.itemElementNameField = value; } } public ResponseStatus status { get { return this.statusField; } set { this.statusField = value; } } public string version { get { return this.versionField; } set { this.versionField = value; } } } public partial class ArtistsID3 { private List<IndexID3> indexField; public ArtistsID3() { this.indexField = new List<IndexID3>(); } public List<IndexID3> index { get { return this.indexField; } set { this.indexField = value; } } } public enum ItemChoiceType { /// <remarks/> album, /// <remarks/> albumList, --- snip ----当我尝试反序列化为Response-Object时，字段Item始终为null，ItemElementName从枚举ItemChoiceType中获取第一个值，但正确设置了版本和状态。 检索到的xml输出看起来像预期的（参见示例）。 虽然有效的是反序列化为ArtistsID3，但后来我失去了地位。
这是代码：
SubsonicApi api = new SubsonicApi(); var request = new RestRequest(); request.Resource = "getArtists.view"; request.AddParameter("v", "1.10.2"); request.AddParameter("c", "no name yet"); // Item always null! // var response = api.Execute<Response>(request); var response = api.Execute<ArtistsID3>(request); public T Execute<T>(RestRequest request) where T : new() { var client = new RestClient(); client.BaseUrl = new System.Uri(BaseUrl); client.Authenticator = new HttpBasicAuthenticator(_accountSid, _secretKey); var response = client.Execute<T>(request); Console.WriteLine("RESPONSE-DATA: " + response.Content); return response.Data; }如果有人能指出正确的方向，我会很高兴，因为我认为正确的方法应该是通过Response对象访问数据。 真的不知道如何调试这种不期望的行为。
I'm new to RestSharp and trying to access my subsonic server through the subsonic-api. Every Response in wrapped in a subsonic-response Tag, e.g.
<subsonic-response xmlns="http://subsonic.org/restapi" status="ok" version="1.10.1"> <artists ignoredArticles="The El La Los Las Le Les"> <index name="A"> <artist id="5449" name="A-Ha" coverArt="ar-5449" albumCount="4"/> <artist id="5421" name="ABBA" coverArt="ar-5421" albumCount="6"/> <artist id="5432" name="AC/DC" coverArt="ar-5432" albumCount="15"/> <artist id="6633" name="Aaron Neville" coverArt="ar-6633" albumCount="1"/> </index> <index name="B"> <artist id="5950" name="Bob Marley" coverArt="ar-5950" albumCount="8"/> <artist id="5957" name="Bruce Dickinson" coverArt="ar-5957" albumCount="2"/> </index> </artists>Xsd generated the following classes for serialization:
public partial class Response { private object itemField; private ItemChoiceType itemElementNameField; private ResponseStatus statusField; private string versionField; [System.Xml.Serialization.XmlChoiceIdentifierAttribute("ItemElementName")] public object Item { get { return this.itemField; } set { this.itemField = value; } } [System.Xml.Serialization.XmlIgnoreAttribute()] public ItemChoiceType ItemElementName { get { return this.itemElementNameField; } set { this.itemElementNameField = value; } } public ResponseStatus status { get { return this.statusField; } set { this.statusField = value; } } public string version { get { return this.versionField; } set { this.versionField = value; } } } public partial class ArtistsID3 { private List<IndexID3> indexField; public ArtistsID3() { this.indexField = new List<IndexID3>(); } public List<IndexID3> index { get { return this.indexField; } set { this.indexField = value; } } } public enum ItemChoiceType { /// <remarks/> album, /// <remarks/> albumList, --- snip ----When I'm trying to deserialize into a Response-Object the field Item is always null and ItemElementName gets the first value from the enum ItemChoiceType but version and status are correctly set. The retrieved xml-output looks like expected (see sample). What works though is deserializing into ArtistsID3 but then I loose the status.
Here's the code:
SubsonicApi api = new SubsonicApi(); var request = new RestRequest(); request.Resource = "getArtists.view"; request.AddParameter("v", "1.10.2"); request.AddParameter("c", "no name yet"); // Item always null! // var response = api.Execute<Response>(request); var response = api.Execute<ArtistsID3>(request); public T Execute<T>(RestRequest request) where T : new() { var client = new RestClient(); client.BaseUrl = new System.Uri(BaseUrl); client.Authenticator = new HttpBasicAuthenticator(_accountSid, _secretKey); var response = client.Execute<T>(request); Console.WriteLine("RESPONSE-DATA: " + response.Content); return response.Data; }I'd be glad if somebody could point me in the right direction as I think the right way should be accessing the data through an Response object. Really don't know how to debug this not expected behaviour.
