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：
