Overloading '=', getting errors

[c#_novice]

Anything wrong with this overloading

TankStatus operator=(int number, TankStatus ts)
{
	return ts = number;
}

//: error C2801: 'operator =' must be a non-static member

TankStatus is enum type....

[GCDEF]

You can only overload operators on classes, structs and unions. MSDN explains that if you look up the error number. Why would you want to overload the = operator on an enum anyway?

because...

if ( (ts>3 ) || (ts<0) ) {
	ts=0 ;
}

// : error C2440: '=' : cannot convert from 'int' to TankStatus'

again, ts is enum.... // enum TankStatus {unknown, empty, half, full};

[GCDEF]

The point of an enum is to provide names for its possible values. You should use those names when assigning it a value, otherwise there's no point in using an enum.

enum TankStatus
{
   unknown,
   empty,
   full
}:

TanksStatus ts;

ts = unknown;

hey you right, thanx

[s_kannan55]

elements of an enum can only be assigned values at the point of declaration.

[kempofighter]

elements of an enum can only be assigned values at the point of declaration.

If you define a variable that happens to be an enum (and it is not a const) you can assign to it as much as you want.

enum colors
{
   RED,
   BLUE,
   GREEN
}

colors textColor (RED);

// later I can do this
textColor = BLUE;

Am I misunderstanding your point?
