问题描述
我有一个 OnClick=Button_Click 的按钮.我想从另一个函数调用 Button_Click 但问题是我需要给它:
I have a button with OnClick=Button_Click. I want to call Button_Click from another function but the problem is that I need to give it:
(object sender, EventArgs e)
我应该为这些参数输入什么?有什么办法解决吗?
What should I enter for those parameters? Is there any way around it?
推荐答案
你可以这样做
Button_Click(null,EventArgs.Empty);
虽然我同意最好提取可以从任何地方调用的函数.
although I agree that it's better to extract function that could be called from anywhere.
例如，如果你有
protected void Button_Click(object sender, EventArgs e)
{
//some list of code
}
这段代码应该放在一些新方法中，然后从 Button_Click 或任何其他方法中调用
this code should be put in some new method and then called from Button_Click or any other method
private void ExtractedMethod()
{
//some list of code
}
protected void Button_Click(object sender, EventArgs e)
{
ExtractedMethod();
}
我建议您阅读Martin Fowler 所著的重构:改进现有代码的设计一书.这是架子上的必备品.你会不时回到那本书，它是永恒的.
I recommend you to read a book Refactoring: Improving the Design of Existing Code by Martin Fowler. It's a must on a shelf. You will come back to that book from time to time, it's timeless.
