如何跟踪按钮按下情况

Question

我是一个建筑物的电力外壳形式，触发继电器开关，并想要保持跟踪哪些按钮被使用，并多次按下每个按钮。

Answer 1

您需要将事件操作块附加到按钮的Click事件，在那里递增您的计数器：

# Create a hashtable to store the button counters at the start of the script
$buttonClickCounters = @{}

# define form components here etc...

# Assuming $button1 contains a System.Windows.Forms.Button:
$button1.add_Click({
  # someone clicked the button, increment counter
  $buttonClickCounters['button1']++

  # implement whatever the button is actually supposed to affect down here
})

表单运行后，您可以通过检查存储在哈希表中的值来检查单个按钮的点击次数：

$buttonClickCounters['button1'] -as [int] # this expression will now resolve to the number of times the first button was clicked
