文件读取：

            Console.WriteLine(Directory.Exists("H:\\CopyFiles1.java"));            return;            StreamReader objReader = new StreamReader("H:\\CopyFiles1.java");                                  string sLine = "";            ArrayList arrText = new ArrayList();            while (sLine != null)            {                sLine = objReader.ReadLine();                if (sLine != null)                    Console.WriteLine(sLine);                    //arrText.Add(sLine);            }            objReader.Close();            //foreach (string sOutput in arrText)            //    Console.WriteLine(sOutput);            Console.ReadLine();
