I know it's awhile since you posted this but for any others that find this! 我知道距您发布此消息已经有一段时间了，但对于其他找到此消息的人来说！

Use a relative path for your images and then to find them relative to your aspx page you use the Server.MapPath and add the relative path to it. 为图像使用相对路径，然后使用Server.MapPath并找到相对于aspx页面的图像，并向其添加相对路径。

eg if (File.Exists( Server.MapPath ("\\Data\\Competitions\\CurrentSeason\\" + round + "\\Intermediate\\Scores.xml"))) 例如，如果（File.Exists（ Server.MapPath （“ \\ Data \\ Competitions \\ CurrentSeason \\” +回合+“ \\ Intermediate \\ Scores.xml”）））
