Switch statement and command

Explains how to use a switch to handle multiple If statements. The If can check many types of conditions, including the value of variables and the properties of objects. To check multiple conditions, use a Switch statement. The Switch statement is equivalent to a series of If statements, but it is simpler.

Switch statement and command

The match expression

A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each switch case. You can have any number of case statements within a switch.

Each case is followed by the value to be compared to and a colon. The constant-expression for a case must be the same data type as the variable in the switch, and it must be a constant or a literal.

A switch statement can have an optional default case, which must appear at the end of the switch. The default case can be used for performing a task when none of the cases is true. The default case can be used for performing a task when none of the cases is true. The switch statement may include at most one default label placed in any switch section. The following example shows a simple switch statement that has three switch sections, each containing two statements. The second switch section contains the case 2: and case 3: labels. Try PowerShell's Switch statement, especially when the 'if' and 'elseif' command becomes to cumbersome. See the -switch examples.

When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached. When a break statement is reached, the switch terminates, and the flow of control jumps to the next line following the switch statement.

Not every case needs to contain a break. If no break appears, the flow of control will fall through to subsequent cases until a break is reached. A switch statement can have an optional default case, which must appear at the end of the switch. The default case can be used for performing a task when none of the cases is true.

No break is needed in the default case.The SWITCH command provides a multipath branch in a program. The specific path taken during program execution depends on the value of the control expression that is specified with SWITCH. You can use a SWITCH statement only within programs.

Note: Do not confuse the use of a single SWITCH command. The body of a switch statement is known as a switch block.

A statement in the switch block can be labeled with one or more case or default labels. The switch statement evaluates its expression, then executes all statements that follow the matching case label.

Switch statement and command

For the switch statement to be meaningful at least one case label command_list clause must be present, while the otherwise command_list clause is optional. If label is a cell array the corresponding command_list is executed if any of the elements of the cell array match expression.

switch is a selection statement that chooses a single switch section to execute from a list of candidates based on a pattern match with the match expression. using System; public class Example { public static void Main() { int caseSwitch = 1; switch (caseSwitch) { case 1: lausannecongress2018.comine("Case 1.
