如何将json字符串转换为yaml

Question

I have the following code segment:

string stringXDoc = JsonConvert.SerializeObject(ConnectedItemOperations.GetConnectedItemById(id).Edits.EditableData);
var json = JsonConvert.DeserializeObject(stringXDoc);

this is the file that getting error : InvalidOperationException: Too much recursion when traversing the object graph. There are 2000+ products.

I want to convert json variable into yaml . stringXDoc is not same all time so that I cannot create class for DeserializeObject<> or can I ? Is there any way to convert this variable to yaml ?

The easiest way is to use the YamlDotNet library. Here's a code example to convert youe object to YAML format:

var yourObject = ConnectedItemOperations.GetConnectedItemById(id).Edits.EditableData;
var serializer = new SerializerBuilder().Build();
var yamlString = serializer.Serialize(yourObject);

I tested this with following code:

class User
{
    public string Name { get; set; }
    public Car[] Cars { get; set; }
}

class Car
{
    public string Make { get; set; }
    public int Year { get; set; }
}

var user = new User
{
    Name = "Me",
    Cars = new Car[]
    {
        new Car { Make = "Car1", Year = 2000 }, 
        new Car { Make = "Car2", Year = 2017 }
    }
};
var serializer = new SerializerBuilder().Build();
var asYaml = serializer.Serialize(user);

This produces following YAML string:

Name: Me

Cars:

• Make: Car1

  Year: 2000

• Make: Car2

  Year: 2017
