                    string path = Server.MapPath("~");
                    string folder = "images\\LmImg\\";
                    string filename = FileUpload1.FileName;
                    FileUpload1.SaveAs(path + folder + filename);

Answer 1

估计你用的是虚拟目录
Server.MapPath("/你的网站文件夹/")

Answer 2

 string path = Server.MapPath("~/images/LmImg/");
  string filename = FileUpload1.FileName;
  FileUpload1.SaveAs(path + filename);

Answer 3

string path = Server.MapPath("~/images/LmImg/");
string filename = FileUpload1.FileName;
FileUpload1.SaveAs(path + filename);

Answer 5

string folder = System.Web.HttpContext.Current.Server.MapPath("/") + "/images/LmImg".Replace("/", "\\") + "\\";你为什么要替换呢？string folder = System.Web.HttpContext.Current.Server.MapPath("~/") + "/images/LmImg/";
