将JSON字符串反序列化到列表时遇到问题

该项目如下：

[JsonObject(MemberSerialization.OptIn)]
    public class TCProject
    {
        public override string ToString()
        {
            return Name;
        }

        [JsonProperty(PropertyName = "archived")]
        public bool Archived { get; set; }

        [JsonProperty(PropertyName = "description")]
        public string Description { get; set; }

        [JsonProperty(PropertyName = "href")]
        public string Href { get; set; }

        [JsonProperty(PropertyName = "id")]
        public string Id { get; set; }

        [JsonProperty(PropertyName = "name")]
        public string Name { get; set; }

        [JsonProperty(PropertyName = "webUrl")]
        public string WebUrl { get; set; }
    }

{"project":[{"name":"GCUK","id":"project11","href":"/httpAuth/app/rest/projects/id:project11"},{"name":"Interiors In Spain","id":"project3","href":"/httpAuth/app/rest/projects/id:project3"}]}

public IEnumerable<TCProject> GetAllProjects()
        {
            var uri = _connection.CreateUri("/httpAuth/app/rest/projects");
            var request = _connection.Request(uri);

            var projects = JsonConvert.DeserializeObject<List<TCProject>>(request);

    return projects;
}

JSON字符串如下所示：

[JsonObject(MemberSerialization.OptIn)]
    public class TCProject
    {
        public override string ToString()
        {
            return Name;
        }

        [JsonProperty(PropertyName = "archived")]
        public bool Archived { get; set; }

        [JsonProperty(PropertyName = "description")]
        public string Description { get; set; }

        [JsonProperty(PropertyName = "href")]
        public string Href { get; set; }

        [JsonProperty(PropertyName = "id")]
        public string Id { get; set; }

        [JsonProperty(PropertyName = "name")]
        public string Name { get; set; }

        [JsonProperty(PropertyName = "webUrl")]
        public string WebUrl { get; set; }
    }

{"project":[{"name":"GCUK","id":"project11","href":"/httpAuth/app/rest/projects/id:project11"},{"name":"Interiors In Spain","id":"project3","href":"/httpAuth/app/rest/projects/id:project3"}]}

public IEnumerable<TCProject> GetAllProjects()
        {
            var uri = _connection.CreateUri("/httpAuth/app/rest/projects");
            var request = _connection.Request(uri);

            var projects = JsonConvert.DeserializeObject<List<TCProject>>(request);

    return projects;
}

转换字符串的代码如下所示：

[JsonObject(MemberSerialization.OptIn)]
    public class TCProject
    {
        public override string ToString()
        {
            return Name;
        }

        [JsonProperty(PropertyName = "archived")]
        public bool Archived { get; set; }

        [JsonProperty(PropertyName = "description")]
        public string Description { get; set; }

        [JsonProperty(PropertyName = "href")]
        public string Href { get; set; }

        [JsonProperty(PropertyName = "id")]
        public string Id { get; set; }

        [JsonProperty(PropertyName = "name")]
        public string Name { get; set; }

        [JsonProperty(PropertyName = "webUrl")]
        public string WebUrl { get; set; }
    }

{"project":[{"name":"GCUK","id":"project11","href":"/httpAuth/app/rest/projects/id:project11"},{"name":"Interiors In Spain","id":"project3","href":"/httpAuth/app/rest/projects/id:project3"}]}

public IEnumerable<TCProject> GetAllProjects()
        {
            var uri = _connection.CreateUri("/httpAuth/app/rest/projects");
            var request = _connection.Request(uri);

            var projects = JsonConvert.DeserializeObject<List<TCProject>>(request);

    return projects;
}

public IEnumerable GetAllProjects（）
{
var uri=_connection.CreateUri（“/httpAuth/app/rest/projects”）；
var request=\u connection.request（uri）；
var projects=JsonConvert.DeserializeObject（请求）；
返回项目；
}

我得到的例外情况是：

Newtonsoft.Json.JSONSerializationException:{“无法将Json对象反序列化为'System.Collections.Generic.List`1[TCProject]'类型。”

---

一定有一些我遗漏了的非常简单的东西-有人有什么想法吗？

我认为在这种情况下，您只需要获取JSON的数组部分即可反序列化到如下列表中：

    public IEnumerable<TCProject> GetAllProjects()
    {
        var uri = _connection.CreateUri("/httpAuth/app/rest/projects");
        var request = _connection.Request(uri);

        var projects = JsonConvert.DeserializeObject<List<TCProject>>(request.Substring(11, request.Length - 1));

        return projects;
    }

public IEnumerable GetAllProjects（）
{
var uri=_connection.CreateUri（“/httpAuth/app/rest/projects”）；
var request=\u connection.request（uri）；
var projects=JsonConvert.DeserializeObject（request.Substring（11，request.Length-1））；
返回项目；
}

我很确定，如果您创建了一个名为project的类，该类具有一个属性，该属性是一个列表，并反序列化到该对象，那么一切都会正常工作

        var p = JsonConvert.DeserializeObject<TCProjectWrapper>( s );
        s = "this"; //for easy breakpointing
    }
}

您接收此消息的方法是什么样子的？整个方法现在都存在了-connection.Request只返回一个JSON字符串-它对itOh没有任何特殊作用，我只是意识到这是一个Silverlight问题。。我从不做Silverlight。。。我不明白为什么我不能在VS中解析这个库…这里没有silverlight-它是纯c#-JsonConvert是Newtonsoft.Json库哦，你应该这么说。。。我在查MSDN JsonConvert的资料那。。。看起来有点不对劲。我认为装饰父对象会更容易。我不认为我可以指望子字符串和每次的长度不幸的是，你还可以创建另一个对象，并使用名为Project的属性反序列化到该对象中，该属性将为你提供一个列表。是的，这就是我最后做的：）这是我曾经做过的我能够下载正确的库。作为参考，我会用我使用的代码更新你的答案。很抱歉，我没有提供完整的示例，我还没有掌握这里的代码示例。
