In C#, Jump statements are used to transfer control from one point to another point in the program due to some specified code while executing the program. There are five keywords in the Jump Statements:

• break
• continue
• goto
• return
• throw

break statement

The break statement is used to terminate the loop or statement in which it present. After that, the control will pass to the statements that present after the break statement, if available. If the break statement present in the nested loop, then it terminates only those loops which contains break statement.

Flowchart:

Example:

// C# program to illustrate the
// use of break statement
using System;
 
class Tech {
 
    // Main Method
    static public void Main()
    {
 
        // TechforTech is printed only 2 times
        // because of break statement
        for (int i = 1; i < 4; i++)
        {
            if (i == 3)
                break;
 
            Console.WriteLine("TechforTech");
        }
    }
}

Output:

TechforTech
TechforTech

Continue Statement

This statement is used to skip over the execution part of the loop on a certain condition. After that, it transfers the control to the beginning of the loop. Basically, it skips its following statements and continues with the next iteration of the loop.

Example:

// C# program to illustrate the
// use of continue statement
using System;
 
class Tech {
 
    // Main Method
    public static void Main()
    {
         
        // This will skip 4 to print
        for (int i = 1; i <= 10; i++) {
 
            // if the value of i becomes 4 then
            // it will skip 4 and send the
            // transfer to the for loop and
            // continue with 5
            if (i == 4)
                continue;
 
            Console.WriteLine(i);
        }
    }
}

Output:

1
2
3
5
6
7
8
9
10

goto statement

This statement is used to transfer control to the labeled statement in the program. The label is the valid identifier and placed just before the statement from where the control is transferred.

Example:

// C# program to illustrate the
// use of goto statement
using System;
 
class Tech {
 
    // Main Method
    static public void Main()
    {
        int number = 20;
        switch (number) {
 
        case 5:
            Console.WriteLine("case 5");
            break;
        case 10:
            Console.WriteLine("case 10");
            break;
        case 20:
            Console.WriteLine("case 20");
 
            // goto statement transfer
            // the control to case 5
            goto case 5;
 
        default:
            Console.WriteLine("No match found");
             
        }
    }
}

Output:

case 20
case 5

return statement

This statement terminates the execution of the method and returns the control to the calling method. It returns an optional value. If the type of method is void, then the return statement can be excluded.

Example:

// C# program to illustrate the
// use of return statement
using System;
 
class Tech {
 
    // creating simple addition function
    static int Addition(int a)
    {
 
        // add two value and
        // return the result of addition
        int add = a + a;
        
        // using return statement
        return add;
    }
 
    // Main Method
    static public void Main()
    {
        int number = 2;
 
        // calling addition function
        int result = Addition(number);
        Console.WriteLine("The addition is {0}", result);
    }
}

Output:

The addition is 4

throw statement

This is used to create an object of any valid exception class with the help of new keyword manually. The valid exception must be derived from the Exception class.

Example:

// C# Program to illustrate the use
// of throw keyword
using System;
 
class Tech {
     
     // taking null in the string
     static string sub = null;
         
    // method to display subject name   
    static void displaysubject(string sub1)
    {
        if (sub1  == null)
            throw new NullReferenceException("Exception Message");
             
    }
 
// Main Method   
static void Main(string[] args)
{
     
    // using try catch block to
    // handle the Exception
    try
    {
         
        // calling the static method
        displaysubject(sub);
    }
     
    catch(Exception exp)
    {
        Console.WriteLine(exp.Message );
    }                    
}
 
}

Output:

Exception Message
