The continue statement in C# let the program skip a block of codes for current iteration in a loop. Whenever continue statement condition is fulfilled, it brings the program to the start of loop. If the continue statement is used in a nested loop (loop inside loop), it will skip innermost loop's code block, whenever condition is fulfilled.
using System;
namespace MyApplication {
class MyProgram {
static void Main(string[] args) {
int i = 6;
int j = 0;
while (j < i){
j++;
if(j == 4){
Console.WriteLine("this iteration is skipped.");
continue;
}
Console.WriteLine(j);
}
}
}
}
1 2 3 this iteration is skipped. 5 6
using System;
namespace MyApplication {
class MyProgram {
static void Main(string[] args) {
for (int i = 1; i <= 6; i++){
if(i == 4 ){
Console.WriteLine("this iteration is skipped.");
continue;
}
Console.WriteLine(i);
}
}
}
}
1 2 3 this iteration is skipped. 5 6
The Continue statement skip the inner loop's block of codes whenever condition is fulfilled. In below mentioned example, program skips the inner loop only when j = 100.
//Nested loop without continue statement
using System;
namespace MyApplication {
class MyProgram {
static void Main(string[] args) {
for (int i = 1; i <= 3; i++){
for (int j = 10; j <= 1000; j = j * 10){
Console.WriteLine(i*j);
}
}
}
}
}
//Nested loop with continue statement
using System;
namespace MyApplication {
class MyProgram {
static void Main(string[] args) {
for (int i = 1; i <= 3; i++){
for (int j = 10; j <= 1000; j = j * 10){
if(j == 100 ){
continue;
}
Console.WriteLine(i*j);
}
}
}
}
}
