StreamRead和StreamWriter的使用

1  //StreamRead来读取一个文件
2             using (StreamReader sr = new StreamReader(@"C:\Users\enle\Desktop\新建文本文档.txt", Encoding.Default))
3             {
4                 while (!sr.EndOfStream)//循环的去读文件
5                 {
6                     Console.WriteLine(sr.ReadLine());
7                 }
8             }
9             Console.ReadKey();

  //StreamWriter写入一个文本文件
            using (StreamWriter strw = new StreamWriter(@"C:\Users\wbrm\Desktop\新建.txt",true  ))//true 表示追加
            {
                //strw.Write("别再能吃苦的年纪选择安逸");
                strw.Write("看我有某有把你覆盖掉");
            }
            Console.WriteLine("写入成功");
            Console.ReadKey();
