Listing 20-23 demonstrates using the StreamReader class. Listing 20-23. Using the StreamReader Class using System; using System.IO; class Listing 23 { static void Main(string[] args) { // create a backing stream MemoryStream memStream = new MemoryStream(); // create a StreamWriter StreamWriter myWriter = new StreamWriter(memStream); // write some values to the stream myWriter.WriteLine("Hello, World"); myWriter.WriteLine(true); myWriter.WriteLine(20172); myWriter.WriteLine(12.345D); // flush the data myWriter.Flush(); // reposition the cursor in the backing stream memStream.Seek(0, SeekOrigin.Begin); // create a stream reader StreamReader myReader = new StreamReader(memStream); // read the strings string value; while ((value = myReader.ReadLine()) != null) { Console.WriteLine("Read Line: {0}", value); } // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } Listing 20-23 uses the StreamReader class to read back the string values written by the StreamWriter class. The ReadLine method returns the next string in the underlying stream or null if the end of the stream has been reached. Compiling and running Listing 20-23 produces the following results: Read Line: Hello, World

The Bitmap class provides the DrawText method, which you can use to put text onto your display. The method accepts the text to be drawn, as well as the font and color to use and the position in which to place the text. The coordinates specify the top-left corner of the text to be drawn. Listing 11-11 demonstrates how you can create a bitmap that s the size of the display, get an embedded font resource, and draw white text using the font (see Figure 11-11). Listing 11-11. Drawing Text ScreenMetrics metrics = ScreenMetrics.GetMetrics(); Bitmap bmp = new Bitmap(metrics.Width, metrics.Height); Font font = Resources.GetFont(Resources.FontResources.NinaB); bmp.DrawText("Hello world.", // text font, // font Color.White, // color 20, 20); // x and y of top left corner bmp.Flush();
