You need to use System.IO.File.Deletenot System.IO.Delete
您需要使用System.IO.File.Delete而不是 System.IO.Delete
string path = "~/Pics/Image1.jpg";
System.IO.File.Delete(Server.MapPath(path))

i would try:
我会尝试：
String FilePath;
FilePath = Server.MapPath("~/Pics/Image1.jpg");
File.Delete(FilePath);

The syntax is:
语法是：
System.IO.File.Delete(Server.MapPath("~/Pics/Image1.jpg"));
You will need to make sure the user your web app is running as has delete (change) permissions on the file you are deleting, however.
但是，您需要确保您的 Web 应用程序运行的用户对您要删除的文件具有删除（更改）权限。
