In this chapter you will learn:
Get to know C# operators
C# has the following operators.
| Operator symbol | Operator name | User- overloadable |
|---|---|---|
| () | Grouping | No |
| . | Member access | No |
| -> | Pointer to struct | No |
| () | Function call | No |
| [] | Array/index | Via indexer |
| ++ | Post-increment | Yes |
| -- | Post-decrement | Yes |
| new | Create instance | No |
| stackalloc | Unsafe stack allocation | No |
| typeof | Get type from identifier | No |
| checked | Integral overflow check on | No |
| unchecked | Integral overflow check off | No |
| sizeof | Get size of struct | No |
| + | Positive value of | Yes |
| - | Negative value of | Yes |
| ! | Not | Yes |
| ~ | Bitwise complement | Yes |
| ++ | Pre-increment | Yes |
| -- | Pre-decrement | Yes |
| () | Cast | No |
| * | Value at address | No |
| Address of value | No | |
| * | Multiply | Yes |
| / | Divide | Yes |
| % | Remainder | Yes |
| + | Add | Yes |
| - | Subtract | Yes |
| << | Shift left | Yes |
| >> | Shift right | Yes |
| < | Less than | Yes |
| > | Greater than | Yes |
| <= | Less than or equal to | Yes |
| >= | Greater than or equal to | Yes |
| is | Type is or is subclass of | No |
| as | Type conversion | No |
| == | Equals | Yes |
| != | Not equals | Yes |
| & | And | Yes |
| ^ | Exclusive Or | Yes |
| | | Or | Yes |
| && | Conditional And | Via & |
| || | Conditional Or | Via | |
| ?? | Null coalescing | No |
