使用C＃或Jobject或NewtonSoft连接2个JSON字符串

Question

Hi given I have 2 json files and I would like to join them

{
    "PropertyOne": "PropOne",
    "PropertyTwo": "PropTwo",
    "PropertyThree": "PropThree"
}

and

{
    "MyObject": {
        "PropertyOne": "PropOne",
        "PropertyTwo": "PropTwo",
        "PropertyThree": "PropThree"
    }
}

How can I join them get the below outcome and be a valid json?

{
"PropertyOne": "PropOne",
"PropertyTwo": "PropTwo",
"PropertyThree": "PropThree",
"MyObject": {
    "PropertyOne": "PropOne",
    "PropertyTwo": "PropTwo",
  "PropertyThree": "PropThree"
}

}

Answer 1

I would suggest using Newtonsoft. It is available via Nuget for easy install.

string json1 = @"{'PropertyOne': 'PropOne','PropertyTwo': 'PropTwo','PropertyThree': 'PropThree'}";
string json2 = @"{'MyObject': {'PropertyOne': 'PropOne','PropertyTwo': 'PropTwo','PropertyThree': 'PropThree'}}";

JObject j1 = JObject.Parse(json1);
JObject j2 = JObject.Parse(json2);

j1.Merge(j2, new JsonMergeSettings {
    MergeArrayHandling = MergeArrayHandling.Union
});

Here you would create your two JSON string objects, parse both of them using JObject. Then using the merge method you can let Newtonsoft take care of it behind the scenes. The resulting j1 object has your desired output.

try below thing

static void Main(string[] args)
    {

        string jsonText = @"
                          {
                            ""PropertyOne"": ""PropOne"",
                            ""PropertyTwo"": ""PropTwo"",
                            ""PropertyThree"": ""PropThree""
                        }";

        string jsonText2 = @"
                        {
                            ""MyObject"": {
                                ""PropertyOne"": ""PropOne"",
                                ""PropertyTwo"": ""PropTwo"",
                                ""PropertyThree"": ""PropThree""
                               }
                        }";

        var JsonObj = JObject.Parse(jsonText);
        var JsonObj2 = JObject.Parse(jsonText2);

        JObject MyObject = JsonObj as JObject;

        MyObject.Add("MyObject", JsonObj2["MyObject"]);

        Console.WriteLine(JsonObj.ToString());
}

it's working for me
