我想将日历自定义为波斯语，但在将CultureInfo设置为以下内容后：

CultureInfo fa = new CultureInfo("fa-IR",true);
Thread.CurrentThread.CurrentCulture = fa;

月份和天数的名称未更改，因此决定覆盖默认日历

我该怎么做呢？

您可以创建

CultureInfo

的子类。它的属性将不是只读的，您可以分配给它。

您可以在呈现控件之前设置线程的CultureInfo，并在呈现控件之后恢复

输出：

下面的示例演示如何使用不同的CultureInfo呈现两个不同的日历

对于像我这样的初学者来说，最重要的是：

您的申请是什么？Winforms、WPF、ASP.Net？这个日历控件是什么？我使用ASP.NET 4和

ASP:calendar

在

PageLoad

或你说的地方使用这个代码有什么不同吗？不，PageLoad是一样的，我没有改变任何东西。这是阿拉伯语而不是波斯语。在我使用了你的代码之后，我再次出现了我所说的日历。@majidgeek-对不起m8！真是帮不上忙！我做winform的工作，我对WebForm一点也不熟悉谢谢。但是，在>=.NET4.5中，在
