我如何用C＃字符串编写json格式：

using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string strNJson = @"{to:'topics/extrafx',notification:{title:{0},text:{1},sound: 'default'}}";

            strNJson = string.Format(strNJson, not_title, not_body);
            streamWriter.Write(strNJson);
            streamWriter.Flush();
        }

请咨询？

Answer 1

Json是对象的文本序列化。因此，您只需要使用这些属性创建一个对象并将其序列化即可。要创建代表您对象的类，您只需将Valid Json粘贴到Json 2 C#。

public class Notification
{
    public string title { get; set; }
    public string text { get; set; }
    public string sound { get; set; }
}

public class RootObject
{
    public string to { get; set; }
    public Notification notification { get; set; }
}

并像这样使用它：

var item = new RootObject {
    to = "topics/extrafx",
    notification = new Notification  {
        title = variableFoo,
        text = variableBar,
        sound = "default"

    }
};
var result = JsonConvert.SerializeObject(item);

尝试此版本：

string not_title, not_body;
not_title = "title";
not_body = "body";  
string strNJson = @"{{'to':'topics/extrafx','notification':{{'title':'{0}','text':'{1}','sound': 'default'}}}}";

strNJson = string.Format(strNJson, not_title, not_body);

Answer 3

    private const string DATA = @"{
                    ""uuid"": ""27c0f81c-23bc-4878-a6a5-49da58cd30dr"",
                    ""status"": ""Work"",
                    ""job_address"": ""Somewhere"",
                    ""job_description"": ""Just a Test API CALL, John Mckinley's Job""}";

“”将数据调用到此

content = new StringContent(DATA, Encoding.UTF8, "application/json");

您可以尝试一下。
