Type casting inside generic class

[Marco Segurini]

Hi,

I am converting a regular class

enum ENUM_TEST
{
test1,
test2,
test3,
}

class enum_no_generic
{
public static bool IsValid(int id)
{
return System.Enum.IsD efined(typeof(E NUM_TEST), (ENUM_TEST)id);
}
}

in a generic class

class enum_t<T>
{
public static bool IsValid(int id)
{
return System.Enum.IsD efined(typeof(T ), (T)id); // line 36
}
}

but I get the following build error:

C:\...\Program. cs(36,50): error CS0030: Cannot convert type 'int' to 'T'

that means that the conversion "(T)id" is not permitted.

Is there any way to achieve my goal?

TIA

Marco.

Re: Type casting inside generic class

Marco,

You don't need that conversion. Enum.IsDefined accepts Object, so you don't
need to cast to anything.

return System.Enum.IsD efined(typeof(T ), id);
