如何在wpf中更改应用程序文化？

Question

这是我的代码。

double value = double.Parse(Utility.GetParamValueOrDefault(omRecord.paramList[i].value, "0"),CultureInfo.CurrentCulture);

这是我得到的错误FormatException：输入字符串格式不正确

我已经阅读了StackOverFlow的一些线程，说我需要将以下代码添加到我的WPF应用程序的main（）中。

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
FrameworkElement.LanguageProperty.OverrideMetadata(typeof(FrameworkElement), new FrameworkPropertyMetadata(
XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));

我仍然得到同样的错误，我的CurrentCulture仍然不是en-US。

Answer 1

试试这个

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("en-US");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-US");

Answer 2

在应用程序开始时，您可以通过这种方式设置CultureInfo

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-US");

如果要在运行时确定CultureInfo，请尝试以下操作：

System.Globalization.CultureInfo currentCulture = Thread.CurrentThread.CurrentCulture;
