C# Windows Phone App 7.1从代码隐藏更改按钮文本

我有5个按钮，它们通过显示一周中几天的名称而动态变化，忽略了周六和周日。我可以在Windows Phone中使用

按钮.Content

来实现这一点吗

现在我试着运行它，但当我想进入包含这些按钮的屏幕时，它不会加载，而是冻结，不会输出

我错过了什么或做错了什么

这是我的密码：

        DateTime datetoday = DateTime.Today;

        for (int i = 0; i < 5; )
        {

            if (datetoday.DayOfWeek == DayOfWeek.Sunday || datetoday.DayOfWeek == DayOfWeek.Saturday)
            {
                //it's saturday of sunday
            }
            else
            {
                if (i == 0)

这会冻结，因为循环会永远运行-

i

从不增加，因为您出现了

i++

行

您的代码可以大大简化。您可以通过以下方式实现相同的目标：

var buttons = new [] {firstButton, secondButton, thirdButton, fourthButton, fifthButton};
var date = DateTime.Now;
foreach (var button in buttons)
{
    while(date.DayOfWeek == DayOfWeek.Sunday || date.DayOfWeek == DayOfWeek.Saturday)
        date = date.AddDays(1);
    button.Content = date.ToString("dddd");
    date = date.AddDays(1);
}

或者，如果您需要特定语言的名称，请使用：

date.ToString("dddd", new CultureInfo("pl-PL"));
