问题描述

我想在第二次单击时取消选中(单选按钮). (例如，我单击一次，它会打一个勾号-我再次单击它会删除它).

I want to uncheck a (radio button) on the 2nd click. (e.g. I click once, it puts a check mark - I click a second time, it removes it).

推荐答案

bool blnState;

public Form1()
{
    InitializeComponent();
}

private void radioButton1_MouseDown(object sender, MouseEventArgs e)
{
    blnState = radioButton1.Checked;
}

private void radioButton1_MouseUp(object sender, MouseEventArgs e)
{
    radioButton1.Checked = !blnState;
}

其中radioButton1是您正在使用的单选按钮的名称.
我已经使用了此控件的mousedown和mouseup事件.

where radioButton1 is the name of the radio button that you are using.
I have used the mousedown and mouseup events of this control.
