exit loop iteration case

[csharpula csharp]

Hello,

I am iterating through objects and have the following case:

foreach (classA objectA in classAList)
{
if (classA.count> 0)
{
//now I need to get out of the foreach loop if so,otherwise to keep
iterating
}

}

What is the best way to do it?

Thanks!

Thanks!

to simply just get out of the iteration is some condition becomes true
you can use break;


foreach (classA objectA in classAList)
{
if (classA.count> 0)
{
break;
//now I need to get out of the foreach loop if so,otherwise to
keeiterating
}
}

You've been given the answer, but just for completion, the opposite (so to
speak) of "break" is "continue." It's used far less and some would probably
argue that if you structure your code right you'll never need to use it.

Those are probably the same people who always use a single exit point
from a method, regardless of how much less readable that makes the
code

Despite people I know advocating having only a single exit point from every
method, I am always much happier doing this

public void DoSomethingIfNotNull(object instance)
{
if (instance == null)
return;

//lots of code here
}

than this

public void DoSomethingIfNotNull(object instance)
{
if (instance != null)
{
//lots of code here
}
}

Exactly. It's just a case of being pragmatic.
