How to change Application Culture in wpf?

Question

Here is my code.

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

this is the error i'm getting FormatException: Input string was not in a correct format

i have read some threads of StackOverFlow saying i need to add into main() of my WPF application the following code.

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)));

i still get the same error and my CurrentCulture is still not en-US.

Answer 1

try this

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

Answer 2

At the start of your application you can set CultureInfo in this way

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

If you want to determine the CultureInfo at runtime try this:

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