CS后台代码
private void Button_Click(object sender, RoutedEventArgs e)
{
    // 获取所有的checkbox 再根据checkbox的属性ischeck是否为true，如果为true证明选中需要获取文本
 
    // 1 获取当前窗口grid下所有控件
    UIElementCollection c1 = grid.Children;
 
    // 2 遍历c1下所有的控件
    // UIElement 控件的类
    string s = "";
    foreach (UIElement element in c1)
    {
        // 3 判断element是不是多选框并且多选
        if (element is CheckBox && ((CheckBox)element).IsChecked == true)
        {
            s += ((CheckBox)element).Content;
        }
    }
    MessageBox.Show(s);
