推荐答案

这对您有所帮助，

你可以以下列方式获取复选框的值，

This may be helpfull to you,
you can get values of check box in following way,

bool didYouCheckTheBox = myCheckbox.IsChecked;  // returns true or false

现在剩下的就是那个，

只需按下按钮即可处理它。

所以你需要的完整代码可能是，

Now remaining is that,
Just handle it working on button click.
So full code you required may be like,

buttonClickFunction()
{
     bool didYouCheckTheBox = myCheckbox.IsChecked;  // returns true or false
     if(didYouCheckTheBox)
     {
         TextBox1.Text = "Checked";
         TextBox2.Text = "";
     }
     else
     {
        TextBox1.Text = "";
        TextBox2.Text = ""Un Checked";
     }
}

private void checkBox_CheckedChanged(object sender, EventArgs e)
{
    var checkboxes = from c in groupBox1.Controls.OfType<CheckBox>()
                        where c.Checked
                        orderby int.Parse(c.Name.Substring(8))
                        select c;

    sb.Clear();

    foreach (var cb in  checkboxes)
    {
        sb.Append(string.Format("This is checkbox {0}", cb.Name.Substring(8)));
        sb.Append(Environment.NewLine);
    }

    textBox1.Text = sb.ToString();
}
