C# Switch

This lesson is part of C# · All levels

Summary

The switch is suitable for choosing actions based on a specific value, such as menu or day of the week. Each case ends at a break so that the execution does not fall to the next case. Modern C# also provides a concise switch expression to return the value of a mapping.

Key points

Switch checks one expression and then runs the case blocks that match the value.
Each case is generally ended with a break; without a break, the execution falls to the next case block.
The default is executed when there is no matching case, similar to else.
Several values can be used in a single block case by separating the values using the colon.
Switch expression with arrow returns value and is suitable for simple mapping.
