string path = Server.MapPath("~/Uploads/Chrysanthemum_3.jpeg");

推荐答案

(如果它是服务器端控件).您需要设置虚拟路径.

Server.MapPath(.")返回正在执行的文件(例如aspx)的当前物理目录.
Server.MapPath("..")返回父目录
Server.MapPath(〜")返回到应用程序根目录的物理路径.
Server.MapPath("/")返回到域名根的物理路径(不一定与应用程序的根相同)

使用

if its a server side control. you need to set the virtual path.

Server.MapPath(".") returns the current physical directory of the file (e.g. aspx) being executed
Server.MapPath("..") returns the parent directory
Server.MapPath("~") returns the physical path to the root of the application
Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

use

string path = Server.MapPath("~") + "/Uploads/Chrysanthemum_3.jpeg"; <br />
imgPicture.ImageUrl = path;
