Error converting DateTime in WebService Method parameter

[Rich Robinson]

Hi,

I have a web service method which takes a DateTime type as a parameter.
The service is UK based, and the dates are passed in to the service in the
UK format dd/MM/yyyy.

On a recent install, the web service method will not accept the UK date
format, erroring with a System.Argument exception, but would take US
formatted dates.

As the DateTime type is a method parameter, I cannot use an IFormatProvider
to Parse the date, and check for any errors. What appears to be happening is
that the Web Service code which runs before my method code runs is trying to
Parse the date, but why would it choose US date?

All locale settings on the machine are English (United Kingdom). I have
checked all the the registry entries under HKU -S....... -Control Panel
-International, and they are all set to English (United Kingdom). I have
also set the globalization element in the web.config file for both the
CurrentCulture and CurrentUICulture to en-GB.

So this appears to be the .NET framework code, perhaps as a result of the
[WebMethod] attribute, deserializing the date, and attempting to create a
DateTime object on behalf of the method, but why is it choosing the en-US
method??

Stack Trace

System.ArgumentException: Cannot convert 31/03/2006 to System.DateTime.

Hi Rich,

Did you check the culture infor for the current thread ?.

System.Globalization.CultureInfo ci =
System.Threading.Thread.CurrentThread.CurrentCultu re;

If that CultureInfo instance is US, some globalization setting is not being
applied correctly in your application.
