StreamReader的几种常用方法

            string path = @"D:	est.txt";
            FileStream filestream = new FileStream(path, FileMode.Open);
            

            using (FileStream stream = File.OpenRead(path))
            {
                using (StreamReader reader = new StreamReader(stream))
                {
                    Console.Write(reader.ReadToEnd());
                    Console.WriteLine("
****************");
                }
             }

            using (FileStream stream = File.OpenRead(path))
            {
                using (StreamReader reader = new StreamReader(stream, Encoding.UTF8, false))
                {
                    Console.Write(reader.ReadToEnd());
                    Console.WriteLine("
****************");
                }
            }

            using (StreamReader reader = new StreamReader(path, Encoding.Default, false, 3))
            {
                Console.Write(reader.ReadToEnd());
                Console.WriteLine("
****************");
            }

            using (StreamReader reader = File.OpenText(path))
            {
                Console.Write(reader.ReadToEnd());
                Console.WriteLine("
****************");
            }

就方便而言，最后一种是最方便的。
