Continue in C#

Continue is one of the many conditional statements that can be used inside a conditional loop block in the C# programming language, which can function as a clause to continue the loop execution after the iterative condition is executed in order to move on to the execution of next iteration in the conditional loop. It is typically used along with the iterative conditional loops like a for-while loop, a do-while loop and a for-each loop.

How Continue statement works in C#?

In the below diagram, when the loop starts and if there is a continue statement, it will stop the current iteration and pass the control to the next iteration by going back to the beginning of the loop.

Flowchart

Below is the flow diagram of the continue statement showing how it is implemented.

Below are the examples that show how it works with looping bodies like for, while, do-while, foreach, and inner loops:

Example #1

a. In the below example, for loop, is used. When the value of the variable is equal to 5, the continue statement will skip the current iteration and jumps to the next iteration to display the value.

<p><strong>b. </strong>In the below example, when the value of the variable is less than 6, it will skip the iteration and jumps to the next iteration where the value is equal or greater than 6 and displays the values.</p>

<p><strong>c. </strong>In the below example, the loop runs ten times and skips the iteration whenever the variable x is an odd number and passes the control to the next iteration and prints the value for variable x when it is even. This is how we can print even number series by using the continue statement.</p>

}
}

In the above example, foreach is used for iteration. An array of an element is initialized, which consists of six elements. When the variable is equal to 25, the continue statement will skip the iteration and passes the control to the next iteration and displays the values.

Conclusion

This is how we can use the continue statement with different looping bodies like for, foreach, while, do-while, etc., and skips the iteration based on the condition. Mostly continue statement is used with for and foreach looping bodies.
