C# 当我按下并释放按钮时，如何调用不同的方法？

当我按下一个按钮时如何调用一个方法，当我松开按钮时如何调用另一个方法

我正在使用我的C WinForms应用程序中的PTT按键通话按钮。

使用和事件

使用和事件

可能类似于以下内容：

    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 确定尝试此操作，在表单中添加一个文本框，将其命名为TextBox1，然后将此代码添加到代码隐藏中：

    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";
    }

也许是这样的也许：

    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");
    }

    }

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