引言

如你所知，更改文化后，所有控件都将使用新的文化。在这个控件中，你可以在一个页面上使用多个日历，并为每个日历更改文化。

重要的是，微软不支持波斯日历的UI。现在你可以非常容易地使用它。你可以从你想要的其他控件继承这个控件，并创建你自定义的控件。

Using the Code

代码非常简单，我只是重写了render方法。在渲染之前和之后，我更改文化，并且仅针对波斯日历，我使用反射来更改日历（夏姆斯日历）。

这是此控件中的重要函数，它向你展示了如何使用波斯日历来实现它。

{
DefaultCulture = new System.Globalization.CultureInfo(
    System.Threading.Thread.CurrentThread.CurrentUICulture.Name);
