服务器上的json文件如下所示：

{"status":"success","data":{"projectId":"572ca0cde163d","sensorId":"572ca2deea163b","createTime":1462514044,"updateTimeStamp":1462514044,"recognPicUrl":"http://192.168.1.115:8500/dddd.jpg","drawingModule":{"subjectTemplateId":"16","drawingUnits":[{"drawingUnitId":"572ca0c4f14c023cdeea163c",
"drawingResources":
[{"resourceUrl":"http://192.168.1.115:8300/dds.png","serviceProps":{},"resourceType":"IMG"}],"drawingComponentId":"1"}],
"templateConfig":{"isVertical":false}},"targetId":"ba0a0d83c657e49eb312"}}

如何读取"isVertical“值？

首先，您的Json是而不是有效。在:和"serviceProps"之间应该有一个“{},”。

以下是对Json数据的固定验证。

{"status":"success","data":{"projectId":"572ca0cde163d","sensorId":"572ca2deea163b","createTime":1462514044,"updateTimeStamp":1462514044,"recognPicUrl":"http://192.168.1.115:8500/dddd.jpg","drawingModule":{"subjectTemplateId":"16","drawingUnits":[{"drawingUnitId":"572ca0c4f14c023cdeea163c",
"drawingResources":
[{"resourceUrl":"http://192.168.1.115:8300/dds.png","serviceProps":{},"resourceType":"IMG"}],"drawingComponentId":"1"}],
"templateConfig":{"isVertical":false}},"targetId":"ba0a0d83c657e49eb312"}}

要回答您的问题，您可以轻松地提取isVertical，方法是创建一个表示所有键的类，然后从该类中提取isVertical。

在Json 5.3发行版中添加对的本机支持。下面的解决方案要求您有5.3及以上版本，并且应该可以工作。使用5.4.0b13进行测试，它可以在5.3上工作。

[System.Serializable]
public class ServiceProps
{
}

[System.Serializable]
public class DrawingResource
{
    public string resourceUrl;
    public ServiceProps serviceProps;
    public string resourceType;
}

[System.Serializable]
public class DrawingUnit
{
    public string drawingUnitId;
    public List<DrawingResource> drawingResources;
    public string drawingComponentId;
}

[System.Serializable]
public class TemplateConfig
{
    public bool isVertical;
}

[System.Serializable]
public class DrawingModule
{
    public string subjectTemplateId;
    public List<DrawingUnit> drawingUnits;
    public TemplateConfig templateConfig;
}

[System.Serializable]
public class Data
{
    public string projectId;
    public string sensorId;
    public int createTime;
    public int updateTimeStamp;
    public string recognPicUrl;
    public DrawingModule drawingModule;
    public string targetId;
}

[System.Serializable]
public class PlayerInfo
{
    public string status;
    public Data data;
}

读取isVertical Json值的代码：

void test()
{
    string messageFromServer = "";
    messageFromServer = "{\"status\":\"success\",\"data\":{\"projectId\":\"572ca0cde163d\",\"sensorId\":\"572ca2deea163b\",\"createTime\":1462514044,\"updateTimeStamp\":1462514044,\"recognPicUrl\":\"http://192.168.1.115:8500/dddd.jpg\",\"drawingModule\":{\"subjectTemplateId\":\"16\",\"drawingUnits\":[{\"drawingUnitId\":\"572ca0c4f14c023cdeea163c\",\r\n    \"drawingResources\":\r\n    [{\"resourceUrl\":\"http://192.168.1.115:8300/dds.png\",\"serviceProps\":{},\"resourceType\":\"IMG\"}],\"drawingComponentId\":\"1\"}],\r\n    \"templateConfig\":{\"isVertical\":false}},\"targetId\":\"ba0a0d83c657e49eb312\"}}";



     PlayerInfo playerInfo;
     playerInfo = new PlayerInfo();
     playerInfo.data = new Data();
     playerInfo.data.drawingModule = new DrawingModule();

     playerInfo.data.drawingModule.drawingUnits = new List<DrawingUnit>();

     for (int i = 0; i < playerInfo.data.drawingModule.drawingUnits.Count; i++)
     {
         playerInfo.data.drawingModule.drawingUnits[i].drawingResources = new List<DrawingResource>();
     }


     playerInfo.data.drawingModule.templateConfig = new TemplateConfig();


     playerInfo = JsonUtility.FromJson<PlayerInfo>(messageFromServer);
     Debug.Log("Status: " + playerInfo.status);
     Debug.Log("Vertical: " + playerInfo.data.drawingModule.templateConfig.isVertical);
 }

像这样

// read your json data into a variable
var jsonData = {"status":"success","data":{"projectId":"572ca0cde163d","sensorId":"572ca2deea163b","createTime":1462514044,"updateTimeStamp":1462514044,"recognPicUrl":"http://192.168.1.115:8500/dddd.jpg","drawingModule":{"subjectTemplateId":"16","drawingUnits":[{"drawingUnitId":"572ca0c4f14c023cdeea163c",
                "drawingResources":[{"resourceUrl":"http://192.168.1.115:8300/dds.png","serviceProps"{},"resourceType":"IMG"}],"drawingComponentId":"1"}],
                "templateConfig":{"isVertical":false}},"targetId":"ba0a0d83c657e49eb312"}};   

//then read it like this
var isVertical = jsonData.templateConfig.isVertical

编辑

它应该是你想要的方式

bool isVertical = (bool)jsondata["drawingModule"]["templateConfig"]["isVertical"];
