One of the VB.NET is , there is also an operator in c # is , they don't do the same thing,

I want to ask, did in VB.NET and c # is the same of the operator or function?

CodePudding user response:

Feeling is in c # is a type of comparison, relative to the=in vb judgment, such as whether a variable is empty:
Is Nothing
IsNot Nothing
Compared with the c #
==null
!=null
