Whenever you overload an operator in C#, you have specific
operator methods created that are related to the operator that you overload.
Hence, when you overload the + operator, the overloaded operator method name is
operator+. Note that all the overloaded operator methods are named
"operator." Further, all operator methods in C# are static. To know
more on static and non-static methods, refer to my post at my blog at the link given
vs Non - Static Methods
Note that operator overloading is a feature of the C#
language, not of the IL. Visual Basic .NET does not support operator
overloading. Hence, if you were to access C# methods from non C# languages,
ensure that you provide some methods that act as a wrapper on your operator
methods to facilitate compliancy. If you have overloaded the + operator in your
C# class, ensure that you have a method (something like Add or AddValues) that
would acts as a wrapper around your operator+ method so as to enable the same
to be accessed from outside.
I would not like to drill down into what are the operators
that can be overloaded in C# and those that cannot be overloaded or the
associated rules. There is plenty of stuff on it. You can find some of them at
the following links.
