如何使用C＃在我的Windows窗体中一次按钮 [英] how to buttonwork at once in my windows form using C#

问题描述

我的问题是按钮形式。

如果我填写数字并单击按钮意味着它显示答案，如果我再次点击它显示我的答案的两倍...这里如何阻止按钮点击不超过一次。或者它只执行一次。

这里是我的编码：

hi here my problem is button in form.
if i fill the number and click the button mean it shows answer, if i click again it show double of my answer... here how to block button click not more than one time. or it execute at only once.
here is my coding:

 if (chk_yoga.Checked)
  {
if (cb_duration.Text == "DAY")
{
    day = 1;
    nday = Convert.ToInt32(cb_days.Text);
    inetamt = inetamt + yoga * nday * day;
    txt_inetamt.Text = inetamt.ToString();
}

 if (cb_duration.Text == "MONTH")
{
     day = 30;
     nday = Convert.ToInt32(cb_days.Text);
    inetamt = inetamt + yoga * nday * day;
    txt_inetamt.Text =inetamt.ToString();
}

这里我带有一些像yoga = 200的值，我有3种类型的值计算...每天，每月，每个会话。

here i carry some value in like yoga= 200, i have 3 type of value calculate ...per day , per month, per session.

推荐答案

如果你真的希望它只执行一次，那么设置

If you truly want it to execute only once, then set

myButton.Enabled = false;

。然后，您可以在发生某些事情时将其设置为再次启用，这样可以重新计算值 - 例如，ComboBox选择中的更改，或者 yoga 的值的更改，或者 nday 等等。

at the end of the routine. You can then set it to enabled again when something happens which makes recalculation worth while - a change in the ComboBox selection for example, or a change in the value of yoga, or nday and so forth.
