asp.net Core webapi 获取应用程序所在目录的三种方式

1. string basePath1 = AppContext.BaseDirectory;

例如：D:\后端项目\testCore\test.WebApi\bin\Debug\net6.0\

2.string basePath2 =Path.GetDirectoryName(typeof(Program).Assembly.Location);

例如：D:\后端项目\testCore\test.WebApi\bin\Debug\net6.0\

3.从ASP.NET Core RC2开始，可以通过依赖注入 IHostingEnvironment 服务对象来取得Web根目录和内容根目录的物理路径，如下所示：

using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
 
namespace AspNetCorePathMapping
{
    public class HomeController : Controller
    {
        private readonly IHostingEnvironment _hostingEnvironment;
 
        public HomeController(IHostingEnvironment hostingEnvironment)
        {
            _hostingEnvironment = hostingEnvironment;
        }
 
        public ActionResult Index()
        {
            string webRootPath = _hostingEnvironment.WebRootPath;
            string contentRootPath = _hostingEnvironment.ContentRootPath;
            //webRootPath: D:\后端项目\testCore\test.WebApi\wwwroot

          // contentRootPath: D:\后端项目\testCore\test.WebApi

            return Content(webRootPath + "\n" + contentRootPath);
        }
    }
}
