C# loop – break vs. continue
Posted By: Anonymous
In a C# (feel free to answer for other languages) loop, what’s the difference between break and continue as a means to leave the structure of the loop, and go to the next iteration?
Example:
foreach (DataRow row in myTable.Rows)
{
if (someConditionEvalsToTrue)
{
break; //what's the difference between this and continue ?
//continue;
}
}
Solution
break
will exit the loop completely, continue
will just skip the current iteration.
For example:
for (int i = 0; i < 10; i++) {
if (i == 0) {
break;
}
DoSomeThingWith(i);
}
The break will cause the loop to exit on the first iteration – DoSomeThingWith
will never be executed. This here:
for (int i = 0; i < 10; i++) {
if(i == 0) {
continue;
}
DoSomeThingWith(i);
}
Will not execute DoSomeThingWith
for i = 0
, but the loop will continue and DoSomeThingWith
will be executed for i = 1
to i = 9
.
