检查目录中是否存在文件，忽略扩展名

DirectoryInfo root = new DirectoryInfo("your_directory_path");FileInfo[] listfiles = root.GetFiles("dummy.*");if (listfiles.Length > 0){  //File exists  foreach (FileInfo file in listfiles)        { //Get Filename and link download here        }}else{  //File does not exist  //Upload}

希望这行得通
