解析JSON文件C#

Question

我有以下要解析成C#的JSON。我尽量避免使用外部库，但如果有必要，我可以使用它们。现在，我正在使用JavaScriptSerializer方法从一个JSON文件中解析出另一个stackoverflow question上的答案。不幸的是，我可以在参考资料下使用任意数量的objectX项，并且它们都有不同的名称。有没有其他方法可以做到这一点？

{
    "FormatVersion" : "2010-09-09",
    "Description" : "My JSON Description",
    "Parameters" : {
        "Product" : {
            "Description" : "Product name",
            "Type" : "String",
            "Default" : "cs42"
        },
        "DifferentObjectSize" : {
            "Description" : "DifferentObjectSize",
            "Type" : "String",
            "Default" : "large"
        },
        "ObjectSize" : {
            "Description" : "Worker size",
            "Type" : "String",
            "Default" : "medium"
        }
     },

    "Resources" : {

        "differentobject" : {
          "Type" : "MyType",
          "Properties" : {
            "InstanceType" : { "Ref" : "DifferentObjectSize" }
          }
        },

        "object1" : {
          "Type" : "MyType",
          "Properties" : {
            "InstanceType" : { "Ref" : "ObjectSize" }
          }
        },

        "object2" : {
          "Type" : "MyType",
          "Properties" : {
            "InstanceType" : { "Ref" : "ObjectSize" }
          }
        },

        "object3" : {
          "Type" : "MyType",
          "Properties" : {
            "InstanceType" : { "Ref" : "ObjectSize" }
          }
        },

        "object4" : {
          "Type" : "MyType",
          "Properties" : {
            "InstanceType" : { "Ref" : "ObjectSize" }
          }
        },

    }
}

如果您考虑使用Json.Net，可以按如下方式解析您的输入字符串

JObject myObj = (JObject)JsonConvert.DeserializeObject(jsonString);
foreach(var resource in myObj["Resources"])
{
    var props = resource.Children<JObject>().First();
    Console.WriteLine(props["Type"] + " " + props["Properties"]["InstanceType"]["Ref"]);
}
