netcore v2-模型綁定的七種用法

/**********************BindingController.cs**********************************/

using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace PocoDemo
{
    public class BindingController:Controller
    {
        //一基本類型綁定
        // binding/repeat?text=dino&number=2
        public IActionResult Repeat(string text,int number)
        {
            return Ok(string.Format("text={0} number={1}", text, number));
        }

        //二 強制從給定源綁定
        //binding/visit?city=newyork
        public IActionResult Visit([FromQuery] string city)
        {
            return Ok(city);
        }

        //三 從頭綁定
        //binding/culture
        public IActionResult Culture([FromHeader(Name ="Accept-Language")] string language)
        {
            return Ok(language);
        }

        //四 從請求體綁定
        public IActionResult Print([FromBody] string content)
        {
            return Ok(content);
        }

        //五 綁定複雜類型
        //binding/showperson?name=zs&age=5
        public IActionResult ShowPerson(Person person)
        {
            return Ok(person.Age + "  " + person.Name);
        }

        //六 綁定基本類型的數組
        public IActionResult ShowEmails([Bind(Prefix ="Email")] IList<string> Emails)
        {
            return Ok(string.Join("  ",Emails));
        }

        //七 綁定複雜類型的數組
        public IActionResult ShowPersons( IList<Person> persons)
        {
            return Ok(persons.Count);
        }

    }
}
