How to represent 0 of short type?

逍遥恶魔

short is Int16, the two are exactly the same

There is no similar way to declare,
can only be
short a = 0;

There is a variable of type object, it may be an integer, small integer, large integer, may be a Boolean value,
The question now is how do I know if the value represented by the variable of this object is 0 or boolean False.
If the variable of this object is obj,
short sv = 0;
object obj = sv;
So how do I show that obj is the value of 0 at this time?
Yes: obj == (short) 0 ???

Also possible:
long lv = 0L;
object obj = lv;
What about this time?

Do I want to compare all (short) 0, (long) 0, (int) 0; false ... etc. one by one?

Only this question is because
object.Equals (lv, 0) cannot be compared.

Do you know what the problem is?

For the object, no one knows what type it is except for the one assigned. Has nothing to do with short

The answer upstairs is wrong ...

It has nothing to do with short, I know.

I want to know whether obj represents 0

Object does not have the concept of 0, it is not necessarily the value type, let alone wait for it not equal to 0.

I now know that it is a value type,
I also know that it puts a short type, or long type, or int type value, and this value is 0,
How do I use the program to judge now!
The one upstairs didn't understand what I meant at all!

E.g:
short a = 0;
object obj = a;
bool b = object.Equals(obj, 0);
System.Console.WriteLine(a);
The output is false, this method Equals is not working. How can we know that the value represented by obj is 0?

(The above is wrong, it is like this)
E.g:
short a = 0;
object obj = a;
bool b = object.Equals(obj, 0);
System.Console.WriteLine(b);
The output is false, this method Equals is not working. How can we know that the value represented by obj is 0?
