You can use jump statement like goto to directly jump from the loop no matter how nested it is https://kodify.net/csharp/loop/break-nested/

You can use return statement to immediately stop execution if the desired condition is false
private static void MyMethod(){

    for(int i=0; i <3; i++){
        // check condition and return  if false
        for(int j=0; j<3; j++){
check condition and return if false
            for(int k=0; k<3; k++){
check condition and return if false
Console.WriteLine("k block");
}
Console.WriteLine("j block");
}
Console.WriteLine("i block");
}
}

Hi Rajesh, refer below code for your reference.
public static void nestedloopOne()
{
     bool exitLoop = false;
     for (int i = 0; i < 10 && !exitLoop; i++)
{
for (int j = 0; j < 10 && !exitLoop; j++)
{
              for (int k = 0; k < 10 && !exitLoop; k++)
{
                   if (true) // add your condition here
{
exitLoop = true; // exits all loop by setting ture.
}
                   else
{
  // other code goes here
}
}
}
}
}

public static string nestedloopTwo()
{
  string message = string.Empty;
    for (int i = 0; i < 10; i++)
{
         for (int j = 0; j < 10; j++)
{
              for (int k = 0; k < 10; k++)
{
  if (true) // add your condition here
{
                       return message = "success"; // return breaks all loop and exit method
}
                  else
{
// other code goes here
}
}
}
}
     return message = "fail";
}

Hi,
Please try below approach.
static void Main()
   {
       F1();
       Console.WriteLine("completed");
   }

   private static void F1(){
        bool condition= true;
       for(int i=0; i <3; i++){
           for(int j=0; j<3; j++){
               for(int k=0; k<3; k++){
                   if(condition){
                       return;
                   }
                   Console.WriteLine("k block");
               }
               Console.WriteLine("j block");
           }
           Console.WriteLine("i block");
       }
   }
