清除Windows窗体中的复选框 [英] clearing checkbox in windows form

问题描述

foreach (Control ctrl in cc)
       {
           TextBox tb = ctrl as TextBox;
           if (tb != null)
               tb.Clear();
           else
               RecursiveClearTextBoxes(ctrl.Controls);
       }

以上我用于重置文本框的代码，有人可以为我提供类似于checkbox

above code i''ve used for resetting textbox, can anybody help me with something similar to this for checkbox

推荐答案

的帮助吗?只需将"TextBox"替换为"CheckBox"，将".Clear()"替换为".Checked = false"

我认为这是日常作业"吗?我似乎已经看过几次了……

If you have managed to do this for TextBoxes, then just replace "TextBox" with "CheckBox", and ".Clear()" with ".Checked = false"

I take it this is "homework of the day"? I seem to have seen this a couple of times already...

foreach (Control ctrl in cc)
       {
           checkbox cb = ctrl as checkbox;
           if (cb  != null)
               cb.Checked = false;
           else
               RecursiveClearTextBoxes(ctrl.Controls);
       }

您可以像上面一样使用as，也可以像下面那样使用is

you can use as like above or you can use is like below

foreach (Control ctrl in cc)
       {
           if (cb  is checkbox)
               cb.Checked = false;
           else
               RecursiveClearTextBoxes(ctrl.Controls);
}
