本文實例展示了DevExpress中SplashScreen的用法，對于C#初學者來說有一定的參考借鑒價值，具體用法如下：

關鍵代碼部分如下：

using DevExpress.XtraSplashScreen;using System;namespace DevExpressUtilHelpV3{  /// <summary>  /// 基于.NET 3.0的 SplashScreen工具類  /// </summary>  public static class SplashScreenToolV3  {    private const bool FadeIn = false;    private const bool FadeOut = true;    private const bool ThrowExceptionIfIsAlreadyShown = false;    private const bool ThrowExceptionIfIsAlreadyClosed = false;    /// <summary>    /// ShowSplashScreen    /// </summary>    /// <param name="type">WaitForm</param>    public static void ShowSplashScreen(Type type)    {      CloseSplashScreen();      SplashScreenManager.ShowForm(null, type, FadeIn, FadeOut, ThrowExceptionIfIsAlreadyShown);    }    /// <summary>    /// CloseSplashScreen    /// </summary>    public static void CloseSplashScreen()    {      if (SplashScreenManager.Default != null)      {        //Thread _task = new Thread(() =>        //{        SplashScreenManager.CloseForm(ThrowExceptionIfIsAlreadyClosed);        //});        //_task.Start();      }    }    /// <summary>    /// SetCaption    /// </summary>    /// <param name="caption">需要設置的Title</param>    public static void SetCaption(string caption)    {      if (SplashScreenManager.Default != null && !string.IsNullOrEmpty(caption))      {        SplashScreenManager.Default.SetWaitFormCaption(caption);      }    }    /// <summary>    /// SetDescription    /// </summary>    /// <param name="description">需要設置的文字提示信息</param>    public static void SetDescription(string description)    {      if (SplashScreenManager.Default != null && !string.IsNullOrEmpty(description))      {        SplashScreenManager.Default.SetWaitFormDescription(description);      }    }  }}

測試代碼如下：

try{ SplashScreenToolV3.ShowSplashScreen(typeof(WaitForm1)); Thread.Sleep(5000); throw new Exception("ccccccccc"); ////Thread.Sleep(5000); //SplashScreenToolV3.SetCaption("正在開始下載...."); ////SplashScreenController.ShowSplashScreen(); //Thread _task1 = new Thread(() => //{ //  for (int i = 0; i < 100; i++) //  { //    SplashScreenToolV3.SetDescription(i.ToString() + "%"); //    Thread.Sleep(1000); //  } //}); //Thread _task2 = new Thread(() => //{ //  for (int i = 0; i < 100; i++) //  { //    SplashScreenToolV3.SetCaption("測試.." + i); //    Thread.Sleep(500); //  } //}); //_task1.Start(); //_task2.Start();}catch (Exception ex){ MessageBox.Show(ex.Message);}finally{ // SplashScreenController.HideSplashScreen();}

測試效果如下圖所示：
