在另一个事件处理程序中调用事件处理程序？ [英] calling a event handler within another event handler?

问题描述

这是简短的示例代码：

private void txtbox1_DoubleClick(object sender, EventArgs e)
{
    button1_Click(object sender, EventArgs e); //can I call button1 event handler?
}

private void button1_Click(object sender, EventArgs e)
{
    MessageBox.Show(txtbox1.Text);
}

我想知道以上述方式编写代码是否可以？

I wonder if it would be okay to code in the above way?

推荐答案

您可以做到-尽管您提供的代码无法编译。看起来应该像这样：

You can do that - although the code you provide can't be compiled. It should look like this:

private void txtbox1_DoubleClick(object sender, EventArgs e)
{
    button1_Click(sender, e);
}

private void button1_Click(object sender, EventArgs e)
{
    MessageBox.Show(txtbox1.Text);
}

但是对于最佳实践和代码可读性，这样做可能更好，尤其是当您不使用发件人和 e 时：

But for best practice and code readability, you're probably better off doing this, especially as you are not making use of sender and e:

private void txtbox1_DoubleClick(object sender, EventArgs e)
{
    ShowMessageBox();
}

private void button1_Click(object sender, EventArgs e)
{
    ShowMessageBox();
}

private void ShowMessageBox()
{
    MessageBox.Show(txtbox1.Text);
}
