C#教程之DevExpress之SplashScreen用法实例

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！
