C# While Loop

Syntax

while(<condition>)
{
//statements
}

C# While loop example:

using System;
public class WhileLoopExample1
{
            public static void Main (string[] args)
            {
            int i=1;
                        while(i<10)
                        {
                                    Console.WriteLine(i);
                                    i++;
                        }
}
}

Output

1
2
3
4
5

C# nested while loop: Nested while loop is almost similar to nested for loop. We can use while loop inside a while loop. The inner will execute n number of time for each iteration of outer loop.

C#  Nested While loop Example:

using System;  
            public class WhileExample  
                {  
                  public static void Main(string[] args)  
                  {  
                      int i=1;    
                      while(i<=3)   
                      {  
                          int j = 1;  
                          while (j<=3)  
                                                  {  
                              Console.WriteLine(i+""+j);  
                              j++;  
                          }  
                          i++;  
                      }    
                 }  
               }

Output

1 1
1 2
1 3
2 1
2 2
2 3
3 1
3 2
3 3

C# infinite while loop example: If we put a condition in while loop that never fails then the loop becomes an infinite loop .

using System;
public class InfiniteWhileLoopExample{
public static void main (String[] args)
{
While(true)
{
            //some statements 
}
}
}
