Is operator overload...

Yes, operator overloading is supported in C#. C# allows you to overload most operators for your custom types, which provides a more natural and intuitive syntax when working with those types[1].

To overload an operator in C#, you define a special method with the operator keyword. The method must be public and static, and at least one of its parameters must be of the type that contains the operator declaration[1].

C# supports overloading the following operators[1][2]:

• Unary operators: +, -, !, ~, ++, --, true, false
• Binary arithmetic operators: +, -, *, /, %, &, |, ^, <<, >>
• Equality operators: ==, !=, <, >, <=, >=

However, there are some operators that cannot be overloaded in C#, such as &&, ||, ?:, is, as, and new[1].

When overloading an operator, you must overload both the == and != operators, or both the < and > operators, or both the <= and >= ...
