推荐答案

我想你甚至不需要你可以使用的计数器一个布尔也可以做多种方式：

I think you don''t even need a counter you can use a boolean as well and you can do it numerous ways:

public class MyProg 
{
   private int counter = 0;

   //Button click event
   private void myButton_click(object sender, EventArgs e) {
      counter++;
   }
}

= OR =

考虑你的按钮''文字是0.

=OR=
consider your button''s text is 0.

protected void myButton_Click(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    btn.Text = (Int32.Parse(btn.Text) + 1).ToString();
}

====================== ====编辑==========================

这是一个更简化的代码。您可以将该函数写入MyButtonHandler。

==========================EDIT==========================
Here is a more simplified code for you. You can write that function to the MyButtonHandler.

Button b1 = CreateMyButton();
b1.Click += new EventHandler(this.MyButtonHandler);
...
void MyButtonHandler(object sender, EventArgs e) {
  ...
}

你好，

听起来你需要一个切换功能：

Hi,
Sounds like you need a toggle functions:

private bool _butonSelected = false;
private void button1_Click(object sender, EventArgs e)
{
   ToggleButtonText()
}

private void ToggleButtonText()
{
    if (_butonSelected)
    {
        button.Text = "Select";
        _butonSelected = false;
    }
    else
    {
 
        button.Text = "Un Select";
        _butonSelected = true;
    }
}

private void btnWhatever_Click(object sender, EventArgs e)
        {
            if(btnWhatever.Text == "Select")
            {
                btnWhatever.Text = "UN Select";
            }
            else if (btnWhatever.Text == "UN Select")
            {
                btnWhatever.Text = "Select";
            }

            // Your code goes here...
        }
