# Should I use and loop, or just a loop?

I have this code:

if(listObj.Any(x => x.id < 0))
{
foreach(ModelClass item in listObj)
{
if(item.id < 0)
{
// code to create a new Obj in the database
}
}
}


But, should I use like this?

foreach(ModelClass item in listObj)
{
if(item.id < 0)
{
// code to create a new Obj in the database
}
}


NOTE: It's unusual to exist id < 0 (I use this to create a temp id for manipulation in the page), but there is a possibility.

Extra info that I found:

Use .Where extension method to filter the records you need:
foreach(ModelClass item in listObj.Where(x => x.id < 0))
