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.IsDefined(typeof(ENUM_TEST), (ENUM_TEST)id);
}
}

in a generic class

class enum_t<T>
{
public static bool IsValid(int id)
{
return System.Enum.IsDefined(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.

Marco,

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

return System.Enum.IsDefined(typeof(T), id);
