当应用程序没有控制台或从文件重定向控制台输入时，无法读取密钥。试试Console.Read

Question

无法让程序读取文件，不知道我在这里做错了什么，欢迎任何建议。 尝试为地址簿执行项目，该文件包含所有人的姓名和地址以及电话号码。

 public Form1()
        {
            string filename = "Addresses.txt";
            ReadFile(filename);
            ReadTokens(filename);
        }//end of main

        static void ReadFile(string filename)
        {
            StreamReader readFile;
            readFile = File.OpenText(filename);
            while (!readFile.EndOfStream)
            {
                Console.WriteLine(readFile.ReadLine());
            }//end of while
            {
                readFile.Close();
                Console.ReadKey();
            }//End of read file
        }
        static void ReadTokens(string filename)
        {
            StreamReader readFile;
            string line;
            char[] delim = { ',' };
            readFile = File.OpenText(filename);
            while (!readFile.EndOfStream)
            {
                line = readFile.ReadLine(); // reads one line at a time
                string[] tokens = line.Split(delim);
                foreach (string str in tokens)
                {
                    Console.WriteLine(str + "\t\t");
                }//end of for each
            }
            Console.ReadKey();
            readFile.Close();
        }//end of ReadTokens
    }//end of program
}//end namespace
