老生常谈C# 中的 StreamReader 和 StreamWriter 类

class Program
{
    static void Main(string[] args)
    {
        Console.ForegroundColor = ConsoleColor.Green;
        Console.Title = "StreamReader and StreamWriter";
        WriteToFile();
        ReadFromFile();
        Console.ForegroundColor = ConsoleColor.Gray;
    }
    public static void ReadFromFile()
    {
        using (StreamReader sr = File.OpenText(@"E:\Programming Practice\CSharp\Console\table.tbl"))
        {
            string tables = null;
            while ((tables = sr.ReadLine()) != null)
            {
                Console.WriteLine("{0}", tables);
            }
            Console.WriteLine("Table Printed.");
        }
    }
    public static void WriteToFile()
    {
        using (StreamWriter sw = File.CreateText(@"E:\Programming Practice\CSharp\Console\table.tbl"))
        {
            sw.WriteLine("Please find the below generated table of 1 to 10");
            sw.WriteLine("");
            for (int i = 1; i <= 10; i++)
            {
                for (int j = 1; j <= 10; j++)
                {
                    sw.WriteLine("{0}x{1}= {2}", i, j, (i * j));
                }
                sw.WriteLine("==============");
            }
            Console.WriteLine("Table successfully written on file.");
        }
    }
}
