菜鸟求助！"TestForWpf.mainWindow"不包含"button1_Click"的定义,并且找不到可接受类型为"TestForWpf.mainWi

[Joanna_yan]

我用的是VS2010的WPF。。。

这是从网上找的，但是这个错误是为什么啊？
"TestForWpf.mainWindow"不包含"button1_Click"的定义,并且找不到可接受类型为"TestForWpf.mainWindow"的第一个参数的扩展方法“button1_Click”(是否缺少 using 指令或程序集引用?)

MainWindow.xaml

<Window x:Class="TestForWpf.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="517" Width="842" Background="White" WindowStartupLocation="CenterScreen">
    <Grid>
        <Button Content="Pop up" Height="23" HorizontalAlignment="Left" Margin="58,38,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>
</Window>

namespace aaa
{
    /// <summary>

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void InitializeComponent()
        {
            throw new NotImplementedException();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            PopupWindow win = new PopupWindow();
            win.Show();
        }
    }
}

这是要弹出的窗口

            timer.Elapsed += new ElapsedEventHandler(timer_Elapsed);
