您可以安装 json 并使用 LINQ to JSON 来查询属性:

You could install json and use LINQ to JSON to query the properties:

var jsonString = @"{ ""Date"": ""2016-12-15"", ""Data"": { ""A"": 4.4023, ""AB"": 1.6403, ""ABC"": 2.3457 } }"; var root = JToken.Parse(jsonString); var properties = root // Select nested Data object .SelectTokens("Data") // Iterate through its children, return property names. .SelectMany(t => t.Children().OfType<JProperty>().Select(p => p.Name)) .ToArray(); Console.WriteLine(String.Join(",", properties)); // Prints A,AB,ABC
