通过本文主要向大家介绍了devexpress实例,devexpress用法,splashscreenmanager,cordova splashscreen,wpf splashscreen等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
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);
}
}
}
}
</div>
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();
}
</div>
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！
