Question

我有一个带有进度条的启动画面，一旦完全加载，主窗口就会打开。但是主窗口根本不打开，并且在进度条完全加载后，启动窗口仍然保持不变。有什么问题？

在App.xaml中，我设置了StartupUri =＆＃34; SplashWindow.xaml＆＃34;

启动窗口代码：

using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
using System.Threading;
using System.Windows.Media.Animation;

namespace Project_1
{
/// <summary>
/// Interaction logic for SplashWindow.xaml
/// </summary>
public partial class SplashWindow : Window
{
    public SplashWindow()
    {
        this.InitializeComponent();


       Duration duration = new Duration(System.TimeSpan.FromSeconds(10));
       DoubleAnimation doubleanimation = new     DoubleAnimation(splash_load.Maximum, duration);
       splash_load.BeginAnimation(ProgressBar.ValueProperty, doubleanimation); 

        if (splash_load.Value==100) //If progress bar (Name = "splash_load") loads completely
        {

        // Close splash window
        this.Close();

        // Open main window
        var mw = new revised_mainwindow();
        mw.Show();

        }

        // Insert code required on object creation below this point.
    }   
}
}

问题与你的逻辑有关。

当if语句执行时splash_load.Value不是100，因为动画已启动但直到此时才结束。完成动画后，您将如何检查此条件。使用Completed Animation事件检查条件并显示主窗口。
