我是靠谱客的博主爱听歌时光，最近开发中收集的这篇文章主要介绍.NET Core Web API，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

.NET 实现

.NET Core：完全实现.NET Standard，可在Windows、macOS和Linux运行

.NET Framework：4.5以上实现.NET Standard，仅Windows。很多独有的框架，如WPF。

Mono：用于Android和所有Apple系统，驱动Xamarin和Unity

UWP：统一微软各类设备（Windows、Xbox、Windows Phone等）

https和http协议

Web API Post实例：

//路由
[ApiController]
public class ValuesController : ControllerBase
{
private static Dictionary<string, AddRequest> DB = new Dictionary<string, AddRequest>();
// POST api/<ValuesController>
[HttpPost]
public AddResponse Post([FromBody] AddRequest req)
{
AddResponse resp = new AddResponse();
try
{
DB.Add(req.ISBN,req);
resp.ISBN = req.ISBN;
resp.message = "交易成功";
resp.result = "success";
}catch(Exception ex)
{
Console.WriteLine(ex.ToString());
resp.ISBN = "";
resp.message = "交易失败";
resp.result = "fail";
}
return resp;
}
/* AddRequest
