如何使用Newtonsoft JSON获取methodLog中的值？

Answer 1

您可以通过为子数据创建类来使用它，并将该子数据类用作父类中的数据类型，然后您可以使用它。

像...

public class MethodLog
{
    public int count { get; set; }
    public string methodName { get; set; }
    public string lastAccessTimestamp { get; set; }
    public bool firstAccessTimestamp { get; set; }
}

public class Data
{
    public string authType { get; set; }
    public string ipAddress { get; set; }
    public List<MethodLog> MethodLog{ get; set; }
    public string requesterGLN { get; set; }
    public string onBehalfOfGLN { get; set; }
    public int totalAccessCount { get; set; }
    public int accessCountPer24Hrs { get; set; }
    public string lastAccessTimestamp { get; set; }
    public string firstAccessTimestamp { get; set; }
    public string firstAccessWithin24hrsTimestamp { get; set; }
}

public class SingleData
{
    public Data data { get; set; }
}

  

注意： - 您可以根据需要更改数据类型

只需为对象创建类并使用DeserializeObject<T>：

void Main()
{
    var json = File.ReadAllText(@"C:\pathtojson.json");
    var result = JsonConvert.DeserializeObject<RootObject>(json);
    //Generic Linqpad output:
    result.methodLog.Dump();

}

public class MethodLog
{
    public int count { get; set; }
    public string methodName { get; set; }
    public long lastAccessTimestamp { get; set; }
    public long firstAccessTimestamp { get; set; }
}

public class RootObject
{
    public string authType { get; set; }
    public string ipAddress { get; set; }
    public List<MethodLog> methodLog { get; set; }
    public string requesterGLN { get; set; }
    public string onBehalfOfGLN { get; set; }
    public int totalAccessCount { get; set; }
    public int accessCountPer24Hrs { get; set; }
    public long lastAccessTimestamp { get; set; }
    public long firstAccessTimestamp { get; set; }
    public long firstAccessWithin24hrsTimestamp { get; set; }
}

结果：
