netcore用静态文件方式显示图片

　　利用静态文件的方式在浏览器中显示本地磁盘图片

在startup中写入如下

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            //判断是否有文件路径
            if (!Directory.Exists(Configuration["AppSettings:ImageUrl"]))
            {
                Directory.CreateDirectory(Configuration["AppSettings:ImageUrl"]);
            }

            app.UseStaticFiles(new StaticFileOptions()
            {
                FileProvider = new PhysicalFileProvider(Configuration["AppSettings:ImageUrl"]),//这里是实际的文件路径
                RequestPath = "/StaticFiles" //这里是虚拟的文件路径，这样可以不对外公布自己的实际路径
            }) ;
}

 
　　在页面调用显示

public IActionResult Index()
        {
            //"D:\\MetroDIS\\CX\\10.47.10.183\\20220611\\50.img"
            string s = "D:\\MetroDIS\\CX\\10.242.22.102\\20220608\\k4.jpg";
            string str = GetValue(s, "X", "g");
            string str2 = GetValue(str, "", "p");
            string str3 = str2 + "pg";

            string header = "http://";
           
            string url = $"{header}{_configuration["AppSettings:ApiHostAdress"]}/StaticFiles{str3}";
            ViewBag.URL = url;
            ViewBag.Con = s;
            return View();
        }
