在mvc应用上使用相对路径定位文件

Question

I want to access to the file on my web project under content folder, and I want to use relative path. Can someone confirm me that I'm using right approach

string file = System.Web.Hosting.HostingEnvironment.MapPath("~/Content/myfile.txt");   

Answer 1

yes its 100% right. When you execute the code outside the context of a http request then HttpContext.Current is null and your code crashes. HostingEnvironment.MapPath always works

Answer 2

In this scenario i have used this approach to get multiple files and it worked fine ,so i recommend this . try it once

 String[] files = Directory.GetFiles(@HostingEnvironment.ApplicationPhysicalPath + "\\Videos\\");
