目标拷贝
using System.IO;
               private static void CopyDirectory(DirectoryInfo OldDirectory, DirectoryInfo NewDirectory)
                {
                        string NewDirectoryFullName = NewDirectory.FullName + @"\" + OldDirectory.Name;                        if ( !Directory.Exists(NewDirectoryFullName) )
                                Directory.CreateDirectory(NewDirectoryFullName);
                        
                        FileInfo[] OldFileAry = OldDirectory.GetFiles();
                        foreach (FileInfo aFile in OldFileAry) 
                                File.Copy(aFile.FullName, NewDirectoryFullName +  @"\" +  aFile.Name, true);                        DirectoryInfo[]        OldDirectoryAry = OldDirectory.GetDirectories();
                        foreach ( DirectoryInfo aOldDirectory in OldDirectoryAry )
                        {
                                DirectoryInfo aNewDirectory = new DirectoryInfo(NewDirectoryFullName);
                                CopyDirectory(aOldDirectory, aNewDirectory);
                        }
                }                //CopyDirectory
                public static void CopyDirectory(string OldDirectoryStr, string NewDirectoryStr)
                {
                        DirectoryInfo OldDirectory = new DirectoryInfo( OldDirectoryStr );
                        DirectoryInfo NewDirectory = new DirectoryInfo( NewDirectoryStr );        
                        FileExec.CopyDirectory(OldDirectory,NewDirectory);
                }

用FileUpload.SaveAs不知道VS2002有沒有這個方法string name = FileUpload1.PostedFile.FileName;
                    FileInfo file = new FileInfo(name);
                    string fileName = file.Name;
                    webFilePath = Server.MapPath("Photo/" + fileName);
                    src = "Photo/" + fileName;
                    FileUpload1.SaveAs(webFilePath);
                    Image1.ImageUrl = src;
                    FileStream fs;
                    fs = File.OpenRead("" + webFilePath + "");
                    byte[] imagedata = new byte[fs.Length];
                    int count = (int)fs.Length;
                    fs.Read(imagedata, 0, count);
                    Conn.Open();
                    StrSql = "update product set imagedata=@imagedata,src=@src where pid='" + pid + "'";
                    cmd = new SqlCommand(StrSql, Conn);
                    cmd.Parameters.AddWithValue("@imagedata", imagedata);
                    cmd.Parameters.AddWithValue("@src", src);
