C# 单击c后删除对象#

我有一个用户可以点击的对象，点击后会显示一个messagebox，点击后的messagebox会希望删除该对象

有没有一个简单的方法可以做到这一点

我的代码

private void redballoon_click(object sender, MouseButtonEventArgs e)
{
    string red_balloon_question = System.Windows.Browser.HtmlPage.Window.Prompt("Question 5X2");

    if (red_balloon_question == "10")
    {
        MessageBox.Show("Well done that is correct, you gain 1 point", "Correct Answer", MessageBoxButton.OK);
        PopBalloonCount++;             
    }
    else
    {
        MessageBox.Show("Incorrect, you loose 1 point", "Wrong Answer", MessageBoxButton.OK);
        PopBalloonCount--;
    }

    score.Content = "Your Score" + " " + Convert.ToString(PopBalloonCount);
    this.lastBalloonClickColor = "red_balloon"; // register the last click
} 

MouseLeftButtonDown="redballoon_click"

XMAL代码

private void redballoon_click(object sender, MouseButtonEventArgs e)
{
    string red_balloon_question = System.Windows.Browser.HtmlPage.Window.Prompt("Question 5X2");

    if (red_balloon_question == "10")
    {
        MessageBox.Show("Well done that is correct, you gain 1 point", "Correct Answer", MessageBoxButton.OK);
        PopBalloonCount++;             
    }
    else
    {
        MessageBox.Show("Incorrect, you loose 1 point", "Wrong Answer", MessageBoxButton.OK);
        PopBalloonCount--;
    }

    score.Content = "Your Score" + " " + Convert.ToString(PopBalloonCount);
    this.lastBalloonClickColor = "red_balloon"; // register the last click
} 

MouseLeftButtonDown="redballoon_click"

因此，一旦消息框消失，我希望删除红色气球，有人知道如何执行此操作吗？

您应该尝试以下代码：

private void redballoon_click(object sender, MouseButtonEventArgs e)
{
    //react only when baloon is clicked by left mouse button
    if (e.LeftButton != MouseButtonState.Pressed)
        return;

    string red_balloon_question = System.Windows.Browser.HtmlPage.Window.Prompt("Question 5X2");

    if (red_balloon_question == "10")
    {
        MessageBox.Show("Well done that is correct, you gain 1 point", "Correct Answer", MessageBoxButton.OK);
        PopBalloonCount++;             
    }
    else
    {
        MessageBox.Show("Incorrect, you loose 1 point", "Wrong Answer", MessageBoxButton.OK);
        PopBalloonCount--;
    }

    score.Content = "Your Score" + " " + Convert.ToString(PopBalloonCount);
    this.lastBalloonClickColor = "red_balloon"; // register the last click

    //hide baloon
    redballoon.Visibility = Visibility.Hidden;
    //or
    redballoon.Opacity = 0.0;
}

您的阳台对象的具体类型是什么？那么为什么不添加

WPF

标记呢？我没有想到，谢谢。既然WPF中的

Image

类不提供

Click

事件，那么

redballoon\u Click

MouseDown

事件吗，您需要完全删除对象或只是隐藏它？只需要添加一些引用，并会让您知道，谢谢。我使用的silverlight不支持，但我正在努力解决这个问题。你也可以使用不透明度技巧，也应该适用于silverlight（在回答中添加）。谢谢，我现在正在解决一些参考问题，一旦我让它工作，我将接受答案。你的问题到底是什么？Visual Studio无法识别

Image

control？错误

“System.Windows.Input.MouseButtonEventArgs”不包含“LeftButton”的定义，并且找不到接受类型为“System.Windows.Input.MouseButtonEventArgs”的第一个参数的扩展方法“LeftButton”（是否缺少using指令或程序集引用？
