c# - 按下并释放按钮时如何调用不同的方法？

Question

如何在按下按钮时调用方法并在释放按钮时调用另一个方法？

我正在使用 C# WinForms 应用程序中的 PTT（按下通话）按钮。

Answer 1

使用MouseDown和MouseUp 事件

Answer 2

private void button1_MouseDown(object sender, MouseEventArgs e)
{
   // button is being pressed
}

private void button1_MouseUp(object sender, MouseEventArgs e)
{
   // button was released
}

Answer 3

也许是这样的：

    private void btn1_MouseDown(object sender, MouseEventArgs e)
    {
        Console.WriteLine("Mouse Button was pressed down on the button");
    }

    private void btn1_MouseUp(object sender, MouseEventArgs e)
    {
        Console.WriteLine("Mouse button Button was released");
    }

单击按钮后查看输出窗口。

更新

好的，试试这个，在表单中添加一个文本框并将其命名为 TextBox1，然后将此代码添加到后面的代码中：

    private void btn1_MouseDown(object sender, MouseEventArgs e)
    {
        this.TextBox1.Text = "Mouse Button was pressed down on the button";
    }

    private void btn1_MouseUp(object sender, MouseEventArgs e)
    {
        this.TextBox1.Text = "Mouse button Button was released";
    }
