DynamicCast()

System::DynamicCast(const TFrom&) function

Performs dynamic cast on Exception objects.

template<typename TTo,typename TFrom> std::enable_if<IsExceptionWrapper<TFrom>::value &&IsExceptionWrapper<TTo>::value &&(std::is_convertible<TTo, TFrom>::value||std::is_base_of<TTo, TFrom>::value), TTo>::type System::DynamicCast(const TFrom &obj)

Template parameters

Parameter	Description
TTo	Target Exception type.
TFrom	Source Exception type.

Arguments

Parameter	Type	Description
obj	const TFrom&	Source pointer.

Return Value

Cast result if cast is allowed.

Deprecated

Left for backwards compatibility. Use ExplicitCast instead.

System::DynamicCast(SmartPtr<TFrom> const&) function

Template parameters

Parameter	Description
TTo	Target pointee type.
TFrom	Source pointee type.

Arguments

Parameter	Type	Description
obj	SmartPtr<TFrom> const&	Source pointer.

Return Value

Cast result if cast is allowed.

Deprecated

Left for backwards compatibility. Use ExplicitCast instead.

System::DynamicCast(SmartPtr<TFrom>) function

Unboxes boxed enum via cast.
