static void Main(string[] args)
        {
          string s;            
          string dir;
          Console.WriteLine("输入文件路径和名字");
          dir = Console.ReadLine();
            StreamReader srd;
            try
            {
                srd = File.OpenText(dir);
            }
            catch
            {
                Console.WriteLine("File open failed");
                return; }
            while (srd.Peek() != 1)
            {
                string str = srd.ReadLine();
                Console.WriteLine(str);
                           }
                           srd.Close();
为什么编译说"srd.Close();
错误    1    只有 assignment、call、increment、decrement 和 new 对象表达式可用作语句    F:\pjq\c#\zzc1\zzc1\Program.cs    35    28    zzc1

StreamReader srd 好象要实例化吧?
