方法一、program.cs 中先启动欢迎窗体,然后注册程序运行空闲去执行主程序窗体相应初始化代码 1 static void Main(string[] args) 2 { 3 Application.EnableVisualStyles(); //样式设置 4 Application.SetCompatibleTextRenderingDefault(false); //样式设置 5 6 7 UIForm.WelcomeForm sp = new UIForm.WelcomeForm(); //启动窗体 8 sp.Show(); //显示启动窗体 9 context = new ApplicationContext(); 10 context.Tag = sp; 11 Application.Idle += new EventHandler(Application_Idle); //注册程序运行空闲去执行主程序窗体相应初始化代码 12 Application.Run(context); 13 }
1 //初始化等待处理函数 2 private static void Application_Idle(object sender, EventArgs e) 3 { 4 5 Application.Idle -= new EventHandler(Application_Idle); 6 if (context.MainForm == null) 7 { 8 MainForm mw = new MainForm(_args); 9 context.MainForm = mw; 10 mw.InitForm(); //主窗体要做的初始化事情在这里,该方法在主窗体里应该申明为public 11 UIForm.WelcomeForm sp = (UIForm.WelcomeForm)context.Tag; 12 sp.Close(); //关闭启动窗体 13 mw.Show(); //启动主程序窗体 14 } 15 16 17 }
方法二、实现一个Splasher类,由主窗体操作欢迎窗体(受益于大神:键盘敲击者cncxz http://www.cnblogs.com/cncxz/archive/2006/07/14/450987.html) 首先创建一个名为ISplashForm的接口,该接口包含一个名为SetStatusInfo的方法以用来在启动屏幕上设置系统加载状态,代码如下: 1 public interface ISplashForm 2 { 3 void SetStatusInfo(string statusInfo); 4 } 然后实现一个Splasher类,负责欢迎窗体的Show、Close和Status更新,代码如下: 1 public class Splasher 2 { 3 private static Form splashForm = null; 4 private static ISplashForm splashInterface = null; 5 private static System.Threading.Thread splashThread = null; 6 private static string tempStatus = string.Empty; 7 8 public static void Show(Type splashFormType) 9 { 10 if (splashThread != null) 11 { 12 return; 13 } 14 if (splashFormType == null) 15 { 16 throw new Exception("必须设置启动窗体"); 17 } 18 splashThread = new System.Threading.Thread(new System.Threading.ThreadStart(delegate() 19 { 20 createInstance(splashFormType); 21 Application.Run(splashForm); 22 })); 23 splashThread.IsBackground = true; 24 splashThread.SetApartmentState(System.Threading.ApartmentState.STA); 25 splashThread.Start(); 26 } 27 public static void Close() 28 { 29 if (splashThread == null || splashForm == null) return; 30 try 31 { 32 splashForm.Invoke(new MethodInvoker(splashForm.Close)); 33 } 34 catch (Exception ex) 35 { 36 Controller.MessageConsole.WriteLog(ex); 37 HttpProxy.LogProxy.DoTask(ex, Controller.SQLiteController.Biz.GetAuthor()); 38 } 39 splashThread = null; 40 splashForm = null; 41 } 42 public static string Status 43 { 44 set 45 { 46 { 47 if (splashInterface == null || splashForm == null) 48 { 49 tempStatus = value; 50 return; 51 } 52 splashForm.Invoke( 53 new splashStatusChangedHandle(delegate(string str) { splashInterface.SetStatusInfo(str); }), 54 new object[] { value } 55 ); 56 } 57 } 58 } 59 private static void createInstance(Type FormType) 60 { 61 object obj = FormType.InvokeMember(null, System.Reflection.BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.CreateInstance, null, null, null); 62 splashForm = obj as Form; 63 splashInterface = obj as ISplashForm; 64 if (splashForm == null) 65 { 66 throw new Exception("启动窗体类型必须是System.Windows.Forms.Form的子类"); 67 } 68 if (splashInterface == null) 69 { 70 throw new Exception("启动窗体必须实现ISplashForm接口"); 71 } 72 if (!string.IsNullOrEmpty(tempStatus)) 73 { 74 splashInterface.SetStatusInfo(tempStatus); 75 } 76 } 77 private delegate void splashStatusChangedHandle(string NewStatusInfo); 78 } 欢迎窗体代码如下: 1 public partial class WelcomeForm : DevExpress.XtraEditors.XtraForm, ISplashForm 2 { 3 public WelcomeForm() 4 { 5 InitializeComponent(); 6 this.FormBorderStyle = FormBorderStyle.None;//取消窗体边框 7 this.ShowInTaskbar = false;//取消任务栏图标显示 8 } 9 10 public void SetStatusInfo(string statusInfo) 11 { 12 this.lbInfo.Text = statusInfo; 13 } 14 } 主窗体需要初始化的地方调用代码如下: Splasher.Status = "正在初始化窗体..."; InitializeComponent(); //一系列初始化操作。。。 //为Splasher.Status复制实现消息通知 Splasher.Close(); program.cs Main函数中实现代码如下: 1 UI.UIForm.Splasher.Show(typeof(UIForm.WelcomeForm)); 2 Application.Run(new MainForm(args));
