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... }
