The simplest C# expressions are literals (for example, integer and real numbers) and names of variables. You can combine them into complex expressions by using operators. Operator precedence and associativity determine the order in which the operations in an expression are performed.
The `??` and `??=` operators are the C# null-coalescing operators. They return the value of the left-hand operand if it isn't null. Otherwise, they return the value of the right-hand operand.
The C# => operator defines lambda expressions and expression bodied members. Lambda expressions define a block of code used as data.
Learn C# programming - for beginning developers, developers new to C#, and experienced C# / .NET developers.
The C# addition operators (`+`, and `+=`) work with operands of numeric, string, or delegate types.
Learn about the C# ternary conditional operator, (`?:`), that returns the result of one of the two expressions based on a Boolean expression's result.
Learn about the C# null-forgiving, or null-suppression, operator that is used to declare that an expression of a reference type isn't null.
C# is a cross-platform general purpose language that makes developers productive while writing highly performant code. With millions of developers, C# is the most popular .NET language. C# has broad support in the ecosystem and all .NET workloads.
C# logical operators perform logical negation (`!`), conjunction (AND - `&`, `&&`), and inclusive and exclusive disjunction (OR - `|`, `||`, `^`) operations with Boolean operands.
Learn about C# operators that perform bitwise logical (AND - `&`, NOT - `~`, OR - `|`, XOR - `^`) or shift operations( `<<`, and `>>`) with operands of integral types.
