How to define the enumeration program inside what type? Quote as follows, whether do int or short, we do have a casting, can directly defined as an int or short?

 
Public enum UniDI0: int 
{
Safety grating=0, 
Magnetic sensors on the collecting plate cylinder=1, 
Collecting plate vacuum negative pressure table=2, 
} 

//or written

 
Public enum UniDI0: short 
{
Safety grating=0, 
Magnetic sensors on the collecting plate cylinder=1, 
Collecting plate vacuum negative pressure table=2, 
}
