C# goto Keyword

C# Code Snippets goto Keyword


In this code snippet, we will take a look at the goto keyword in C#.

goto is used to move the control of your program to a label you define beforehand. This can be useful to get out of nested loopsif statements or any nested code blocks in general.

You can even make a DIY loop or method using the goto keyword 😁(But you should of course use the regular loops and methods).

Let’s have a look at the code below to see how to use goto.


using System;

namespace gotoStatement
    class Program
        static void Main(string[] args)
            //The goto keyword can be used to redirect the flow of your program to a marked point.
            //You can make a mark/tag by just writing some text and ending it with a :
            //Then you can point at it using goto. 
            //See examples bellow:

            #region Break out of loop using goto

            for (int i = 0; i < 10; i++)
                for (int j = 0; j < 10; j++)
                    if (i == 5 && j == 2)
                        goto breakOutOfLoop;

            breakOutOfLoop: Console.WriteLine("Loop was ended.");


            #region DIY loop using goto.

            int k = 0; //Declare and initilize counter.

            loopBegin: //Mark beginning point.
                Console.WriteLine(k);//Execute code inside loop.

            k++; //Increment loop counter.
            if (k < 5) //Check if counter is smaller than 5. If so ... 
                goto loopBegin; //Go to the beginning.
