.NET/C#:如何在"触发"事件时删除/最小化代码混乱

Question

我只是想知道是否有一种方法可以最大限度地减少我的应用程序中的代码混乱.

我编写的代码类似于:

   private void btnNext_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnNext.Opacity = 1;
    }

    private void btnNext_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnNext.Opacity = 0.5;
    }

    private void btnShowAll_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnShowAll.Opacity = 1;
    }

    private void btnShowAll_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnShowAll.Opacity = 0.5;
    }

    private void btnPrev_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnPrev.Opacity = 1;
    }

    private void btnPrev_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnPrev.Opacity = 0.5;
    }

    private void btnSearch_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnSearch.Opacity = 1;
    }

    private void btnSearch_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnSearch.Opacity = 0.5;
    }

    private void btnSearchStore_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnSearchStore.Opacity = 1;
    }

    private void btnSearchStore_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnSearchStore.Opacity = 0.5;
    }

    private void btnCloseSearch_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnCloseSearch.Opacity = 1;
    }

    private void btnCloseSearch_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnCloseSearch.Opacity = 0.5;
    }

    private void btnHome_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnHome.Opacity = 1;
    }

    private void btnHome_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        btnHome.Opacity = 0.5;
    }

等等等等...

我是否需要创建一个最初运行的"功能"？或者我是否必须创建另一个类才能"组织"它们？

有什么建议？

Answer 1

您可以将所有这些功能重写为2:

private void FadeBtn_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
{
    Button btn = (Button)sender;
    btn.Opacity = 1;
}

private void FadeBtn_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
{
    Button btn = (Button)sender;
    btn.Opacity = 0.5;
}

然后将MouseEnter和MouseLeave事件的所有按钮指向这些功能.
