我尝试在用户能够更改语言,日期格式等的地方实现多文化应用程序.我编写了core,但是它返回Exception: System.InvalidOperationException:实例为只读.
I try to implement multicultural application where users able to change language, date format and etc. I wrote core but it returns Exception: System.InvalidOperationException: Instance is read-only.
switch (culture) { case SystemCulture.English: Thread.CurrentThread.CurrentCulture = new CultureInfo(CultureCodes.English); Thread.CurrentThread.CurrentUICulture = new CultureInfo(CultureCodes.English); break; //another cultures here } switch (cultureFormat) { case SystemDateFormat.European: var europeanDateFormat = CultureInfo.GetCultureInfo(CultureCodes.Italian).DateTimeFormat; Thread.CurrentThread.CurrentCulture.DateTimeFormat = europeanDateFormat; Thread.CurrentThread.CurrentUICulture.DateTimeFormat = europeanDateFormat; break; //another cultures here }我在互联网上找到了一些信息,我必须使用我所在文化的新实例对象,我更改了代码,只是添加了以下内容:
I found some information on internet and i have to use new instance object of my culture, i changed my code just adding:
CultureInfo myCulture; switch (culture) { case SystemCulture.English: myCulture= new CultureInfo(CultureCodes.English); break; }下面是开关,下面是波纹管:
and bellow, out of switch :
Thread.CurrentThread.CurrentCulture = cultureInfo;我对线程不熟悉,不确定我使用的是否正确.你能建议我如何正确地做到这一点吗?
I'm not familiar with Threads and i'm not sure if i used is correctly. Could you please suggest me how to do this it right way ?
推荐答案您收到 Instance is read-only 错误,因为您试图通过下面的代码.
You get the Instance is read-only error because you are trying to alter a property on a a read-only culture, via the code below.
Thread.CurrentThread.CurrentCulture.DateTimeFormat = europeanDateFormat;您可以通过其 IsReadOnly 属性检查区域性是否为只读;内置的是.
You can check whether a culture is readonly via its IsReadOnly property; the built-in ones are.
相反,您必须对当前活动的区域性进行克隆/复制,在该克隆上进行任何更改,然后将其分配给的 CurrentCulture 和/或 CurrentUICulture 当前线程.
Instead, you must make a clone/copy of the currently active culture, apply any changes on that clone and assign that one to the CurrentCulture and/or CurrentUICulture of the current thread.
var clone = Thread.CurrentThread.CurrentCulture.Clone() as CultureInfo; clone.DateTimeFormat = CultureInfo.GetCultureInfo("it").DateTimeFormat; Thread.CurrentThread.CurrentCulture = clone; Thread.CurrentThread.CurrentUICulture = clone;更多推荐
实例是只读异常,而在asp.net中更改区域性
