Question

我有一个按钮数组，它在运行时动态生成。我的代码中有按钮单击功能，但我找不到在代码中设置按钮的单击名称的方法。所以，

XAML的等效代码是什么：

<Button x:Name="btn1" Click="btn1_Click">

或者，我应该为“????”放置什么在以下代码中：

Button btn = new Button() {
{1}} {
{1}}

Answer 1

Button btn = new Button();
btn.Name = "btn1";
btn.Click += btn1_Click;

private void btn1_Click(object sender, RoutedEventArgs e)
{
    // do something
}

Answer 2

以下应该可以解决问题：

btn.Click += btn1_Click;

Answer 3

// sample C#
public void populateButtons()
{
    int xPos;
    int yPos;

    Random ranNum = new Random();

    for (int i = 0; i < 50; i++)
    {
        Button foo = new Button();
        Style buttonStyle = Window.Resources["CurvedButton"] as Style;

        int sizeValue = ranNum.Next(50);

        foo.Width = sizeValue;
        foo.Height = sizeValue;
        foo.Name = "button" + i;

        xPos = ranNum.Next(300);
        yPos = ranNum.Next(200);

        foo.HorizontalAlignment = HorizontalAlignment.Left;
        foo.VerticalAlignment = VerticalAlignment.Top;
        foo.Margin = new Thickness(xPos, yPos, 0, 0);

        foo.Style = buttonStyle;

        foo.Click += new RoutedEventHandler(buttonClick);
        LayoutRoot.Children.Add(foo);
   }
}

private void buttonClick(object sender, EventArgs e)
{
  //do something or...
  Button clicked = (Button) sender;
  MessageBox.Show("Button's name is: " + clicked.Name);
}

Answer 4

我认为WPF不支持您要实现的目标，即使用方法名称或btn1.Click =“btn1_Click”为按钮分配方法。您将不得不使用上述答案中建议的方法，即使用适当的方法注册按钮点击事件 btn1。点击+ = btn1_Click;

Answer 5

你应该放在

之下

btn.Click = btn.Click + btn1_Click;

WPF按钮单击C＃代码
