本文实例展示了DevExpress中SplashScreen的用法，对于C#初学者来说有一定的参考借鉴价值，具体用法如下：

关键代码部分如下：

using DevExpress.XtraSplashScreen;using System;namespace DevExpressUtilHelpV3{ /// <summary> /// 基于.NET 3.0的 SplashScreen工具类 /// </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">需要设置的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">需要设置的文字提示信息</param> public static void SetDescription(string description) { if (SplashScreenManager.Default != null && !string.IsNullOrEmpty(description)) { SplashScreenManager.Default.SetWaitFormDescription(description); } } }}

测试代码如下：

try{ SplashScreenToolV3.ShowSplashScreen(typeof(WaitForm1)); Thread.Sleep(5000); throw new Exception("ccccccccc"); ////Thread.Sleep(5000); //SplashScreenToolV3.SetCaption("正在开始下载...."); ////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("测试.." + i); // Thread.Sleep(500); // } //}); //_task1.Start(); //_task2.Start();}catch (Exception ex){ MessageBox.Show(ex.Message);}finally{ // SplashScreenController.HideSplashScreen();}

测试效果如下图所示：

希望本文所述方法对打击的C#程序设计能有所帮助！
