C# Operators

Although most of C# ’ s operators should be familiar to C and C++ developers, this section discusses the most important operators for the benefit of new programmers and Visual Basic converts, as well as to shed light on a number of the changes introduced with C#.

C# supports the operators listed in the following

 

Category	Operator
Arithmetic	+ - * / %
Logical	& | ^ ~ && || !
String concatenation	+
Increment and decrement	++ --
Bit shifting	<< >>
Comparison	== != < ><= >=
Assignment	= += -= *= /= %= &= |= ^= <<= >>=
Member access (for objects and structs)	.
Indexing (for arrays and indexers)	[ ]
Cast	( )
Conditional (the ternary operator)	?:
Delegate concatenation and removal	+, -
Type information	sizeof is typeof as
Overflow exception control	checked unchecked
Indirection and address	[ ]
Namespace alias qualifier	: :
Null coalescing operator	??

 

Note that four specific operators (sizeof, *, ->, and &, given in the table below), however, are available only in unsafe code (code that is independent of C # 's type - security),  "Memory Management and Pointers." It is also important to note that the sizeof operator keywords, when used with the. NET Framework 1.0 and 1.1, require unsafe mode. This is not a since the requirement. NET Framework 2.0.
