I have this code :
using System;using System.Collections;using System.Diagnostics;using freetrain.world;namespace freetrain.framework.graphics{ /// <summary> /// Repository of pictures. /// </summary> public class PictureManager { /// <summary> /// Event fired when a DirectDraw surface is found to be lost. /// </summary> public static EventHandler onSurfaceLost; /// <summary> /// Dictionary of id->Picture /// </summary> private static readonly IDictionary dic = new Hashtable(); // prohibit instance creation private PictureManager() {} static PictureManager() { onSurfaceLost += new EventHandler(_onSurfaceLost); World.onNewWorld += new EventHandler(reset); } /// <summary> /// Get the picture with a given id, or throw an exception. /// </summary> /// <returns> /// Always return a non-null valid object. /// </returns> public static Picture get( string id ) { Picture pic = (Picture)dic[id]; if( pic == null ) throw new GraphicsException("unable to find picture of "+id); return pic; } /// <summary> /// Checks if a picture of the specified ID is already registered. /// </summary> public static bool contains( string id ) { return dic[id]!=null; } /// <summary> /// Add a new picture. /// </summary> public static void add( Picture pic ) { if( dic[pic.id]!=null ) throw new GraphicsException("picture "+pic.id+" is already registered"); dic.Add(pic.id,pic); } /// <summary> /// Called by Clock at sunrise and sunset. /// /// invalidates all the surfaces so that they will be reloaded. /// Since this is a static method, it cannot be registered as an ordinary clock handler. /// </summary> public static void reset() { foreach( Picture pic in dic.Values ) pic.setDirty(); } private static void reset( object sender, EventArgs e ) { reset(); } /// <summary> /// Called when DirectDraw surfaces are lost. This method releases the pictures. /// </summary> private static void _onSurfaceLost( object sender, EventArgs e ) { Debug.WriteLine("DirectDraw surfaces are lost"); foreach( Picture pic in dic.Values ) pic.release(); } // TODO: priodical surface eviction }} How can I use it?What I must do to run this code .. and obtain an result?pls some intruction..step by step like .. firt u must open --c# 2 ..3.. pls guys!
