如何分配点击事件

发布于 2024-10-19 00:37:41 字数 290 浏览 3 评论 0原文

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

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？在下面的代码中：

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

原文

I have an array of button which is dynamically generated at run time. I have the function for button click in my code, but I can't find a way to set the button's click name in code. So,

what is the code equivalent for XAML:

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

Or, what should I place for "????" in the following Code:

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

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

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

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

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

以下应该可以解决问题：

btn.Click += btn1_Click;

The following should do the trick:

btn.Click += btn1_Click;
