IResourceProvider.GetObject Method (String, CultureInfo)
Returns a resource object for the key and culture.
Assembly: System.Web (in System.Web.dll)
Parameters
- resourceKey
-
Type:
System.String
The key identifying a particular resource.
- culture

Type:
System.Globalization.CultureInfo
The culture identifying a localized value for the resource.
Return Value
Type: System.ObjectAn Object that contains the resource value for the resourceKey and culture.
When implemented, the GetObject method returns the localized value for a resource key based on the current culture. The implementing class could retrieve the CurrentUICulture property if a value for the culture parameter is not passed in.
The following code example shows a customized resource provider factory that retrieves cached values. The resource provider factory creates an instance of a customized resource provider that implements IResourceProvider. The resource provider includes a customized GetObject method.
