Asp.Net Core JsonPatch使用

實體類

    public class School
    {
        public string Location { get; set; }
        public string Country { get; set; }
        public List<Student> Students { get; set; }
    }

    public class Student
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }

服務端程序

        [HttpPatch]
        public ActionResult Patch([FromBody]JsonPatchDocument<School> jsonPatch)
        {
            if (!ModelState.IsValid)
                return Ok(ModelState.Values);
            var s = new School
            {
                Location = "CN",
                Country = "SH",
            };
            jsonPatch.ApplyTo(s);
            return Ok(s);
        }
