        }
        private void button3_Click(object sender, EventArgs e)

推荐答案

让我试着解密你的问题。



如果我理解，你有一系列的按钮和复选框。



你想带一个通用的例程，它会根据复选框的状态返回一条消息。



如果是这种情况，您可以创建一个新方法并传递控件名称（复选框）。这样的事情：

Let me try to decrypt your question.

If I understand, you have a series of buttons and checkboxes.

And you want to come with a generic routine which would return you a message based on the state of a checkbox.

If that's the case, you could create a new method and pass the control name (checkbox). Something like this:

private string GetMessage(string checkBoxName)
{
	if((CheckBox(this.Controls[checkBoxName])).Checked)
	{
		return string.Format("{0} is checked", checkBoxName);
	}
	else
	{
		return string.Format("{0} is not checked", checkBoxName);
	}
}

private void button1_Click(object sender, EventArgs e)
{
	MessageBox.Show(GetMessage("checkBox2"));
}

private void button2_Click(object sender, EventArgs e)
{
	MessageBox.Show(GetMessage("checkBox1"));
}

使用房产怎么样？它基本上就是你所拥有的：

What about using a property? It's basically what you have there already:

private string Test
{
    get
    {
        if (checkBox1.Checked)
        {
            return "text 1";
        }
        else
        {
            return "text 2";
        }
    }
}

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