C# 将TextBlock绑定到MouseEventHandler

我试图将一个简单的字符串绑定到一个文本块，但它没有任何作用

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

        this.MouseMove += new MouseEventHandler(window_MouseMove);
    }

    public void window_MouseMove (object sender, MouseEventArgs e)
    {
        Point mouseXY = Mouse.GetPosition(this);

        string mouseXYstring = mouseXY.ToString();
    }
}

还有XAML…：

<TextBlock x:Name="MousePosition" HorizontalAlignment="Right"
VerticalAlignment="Top" Width="200" Text="{Binding Path=mouseXYstring}" />

我试着把它放在一个文本框里，它能正常工作。这是我的代码

//mousemove inside my Textbox
    private void TextBox_MouseMove_1(object sender, MouseEventArgs e)
    {
        //txt is the name oh my textbox
        txt.Text = e.GetPosition(this).ToString();
    }

    //mousemove in my windows
    private void wn_MouseMove(object sender, MouseEventArgs e)
    {
        //txt is the name oh my textbox
        txt.Text = e.GetPosition(this).ToString();
    }

但是在你的例子中，你使用一个textblock并尝试这个代码

 public void window_MouseMove (object sender, MouseEventArgs e)
{
    MousePosition.text = e.GetPosition(this).ToString();
}

这就解决了问题，我在活动前错过了“e”，所以我并没有用我的GetPosition给MouseEventArgs打电话。

//mousemove inside my Textbox
    private void TextBox_MouseMove_1(object sender, MouseEventArgs e)
    {
        //txt is the name oh my textbox
        txt.Text = e.GetPosition(this).ToString();
    }

    //mousemove in my windows
    private void wn_MouseMove(object sender, MouseEventArgs e)
    {
        //txt is the name oh my textbox
        txt.Text = e.GetPosition(this).ToString();
    }

 public void window_MouseMove (object sender, MouseEventArgs e)
{
    MousePosition.text = e.GetPosition(this).ToString();
}
