推荐答案

要获取Web root，请使用Server.MapPath并为其指定虚拟路径。

To get web root you use Server.MapPath and give it the virtual path.

String path = Server.MapPath("~/image_logo/ImageName.gif");

将返回L：\chikardarin WebSite \ WebApplication2 \ image_Logo \ ImageName.gif，假设WebApplication2是您的根。

will return L:\chikardarin WebSite\WebApplication2\image_Logo\ImageName.gif assuming that WebApplication2 is your root.

string filename = Server.MapPath("~/image_logo/" + ImgName);
if (System.IO.File.Exists(filename))
{
    System.IO.File.Delete(filename);
    Response.Write("Deleted");
}
