C# Jump Statements

There are several jump statements available in C#, those are a break, continue, goto, return, and throw. In this article, we discuss each of these jump statements with an example. 

Break statement: The break statement used to end the switch statement execution or execution of the body of an iteration as shown below. 

class Program

{

        static void Main(string[] args)

        {

            int value = 1;

            switch (value)

            {

                case 1:

                    Console.WriteLine("Value is One");

                    break;               

                default:

                    Console.WriteLine("No Value");

                    break;

            } 

            for (int n = 0; n < 50; n++)

            {

                if (n == 10)

                {

                    break;

                }

                DoThings();

            } 

        }

       private static void DoThings()

      {

      }

} 

Continue statement: We can use continue statement inside a for loop statement. The continue statement forgoes the remaining statements inside for loop and makes an early call to next iteration like below. 

class Program

{

        static void Main(string[] args)

        {

            for (int n = 0; n < 50; n++)

            {

                if (n == 10)

                {

                    continue;

                }

                DoThings();

            }

        } 

        private static void DoThings()

        { 

        }

}  

Goto statement: The go tot statement is used to transfer the execution to a specific label in C#. In C#, the label is a placeholder in a code block that precedes a statement and specified with a colon as a suffix. 

class Program

{

     static void Main(string[] args)

     {

          int n = 100;

          if(n>90)

          {

              goto Found;

          }

        Found:

            Console.WriteLine("The number {0} is found.", n);

            Console.ReadLine();

      }

}

Return statement: The return statement exits from the true method and returns a specific type of data for non-void methods as shown below. 

class Program

{

        static void Main(string[] args)

        {

            string sValue = DoThings();

        } 

        private static string DoThings()

        {

            return "return value";

        }

} 

We can place return statement anywhere in a method others than in a finally block. We cannot mention return statement in the finally block. 

Throw statement: By using throw statement, we can throw an exception to indicate an error has occurred. 

class Program

{

        static void Main(string[] args)

        {

            DoThings();

        } 

        private static void DoThings()

        {

            Exception ex = new Exception();

            throw ex;

        }

}
