What is a conditional operator in C Sharp?
A condition operator in C # is an operator that uses three operands (conditions to check), the value when the condition is true and the value when the condition is false.
A conditional operator is represented by the symbol '?:'. The first operand (given before the '?:') Is the evaluating (conditional) expression. It must be such that the type of the evaluated expression can be implicitly converted to 'bool' or that the operator 'true' is implemented in order to avoid compilation errors. The second and third operands control the type of conditional expression. It is used more often in assignment, rather than as a compilation error statement.
If the return value of the first operand (conditional expression) is true, the second operand is evaluated. Otherwise the third operand is evaluated. Therefore, the result of the conditional operator is the result of the evaluation of the expression under consideration for evaluation.
For an expression called x? A: b is designated, the operand a is evaluated if only the operand x (the conditional expression) returns true. Otherwise the operand b is evaluated.
This term is also known as the ternary operator or inline if (iif).
A conditional operator is the only ternary operator (using three operands) in C #. It is an alternative to the if-else construct that provides better conciseness with less code and better readability. During compilation, the C # compiler translates the ternary expression into branch statements that combine multiple if statements and reduce nesting at the source code level. Sometimes the code generated for a ternary operator can improve performance by rearranging some statements.
Properties of a conditional operator are:
It's right-associative, which means operations are grouped from right to left.
It always evaluates one of the two expressions specified after the conditional operator symbol. It never rates both.
The first operand must be of the integral or pointer type.
The second and third operands must be convertible into one another and not mutually convertible into a different type.
The type of the result is the general type, which is a l-value, but only if both the second and third operands are of the same type and both are l-values.
Only assignment call, increment, decrement and new object expression can be used as an instruction.
If the result of evaluating an expression that uses the ternary operator is used in a return statement of the method, its type should match the
Match the return type of the wrapping method for successful compilation.
If the result is not a constant, the type of conditional expression is based on the more common of the two types.
