asp.net core 动态生成文件下载
一、创建action public class importController : BaseController { private IWebHostEnvironment _hostingEnvironment = null; public importController(IWebHostEnvironment hostingEnvironment ) { _hostingEnvironment = hostingasp.net api 下载文件与.net 5.0 下载文件
1.asp.net api 下载文件 [HttpGet] public HttpResponseMessage DownFile(string fileName) { try { string filefullPath = Path.Combine(System.Web.HttpContext.Current.Request.PhysicalApplicationPatasp.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 CoreASP.NET中Long-Running任务简析
首先,不推荐在ASP.NET后台中,启动Long-Running的任务。因为无论是用的Task还是ThreadPool.QueueUserWorkItem,ASP.NET不会知道它们在后台运行,这会产生一些问题,比如: 当修改web.config的时候,会触发Appdomain被回收(尽管此时IIS web服务器进程w3wp.exe仍然活着),IIS本身也会每29小时回收应.net core图片上传详解
首先有一点先确认下.net core 不存在Server.MapPath这个方法所以想引用服务器根目录或者web根目录应该在controller中引入IWebHostEnvironment对象 private readonly IWebHostEnvironment _hostingEnvironment; public AdvertisementsController(IWebHostEnvironment ho.netcore 获取项目相关路径
public class BorrowDataController : Controller { private readonly IHostingEnvironment _hostingEnvironment; public BorrowDataController(IHostingEnvironment hostingEnvironment) { _hostingEnvironment = hostingEnvironment
