Hi,
I'm working on a project that has some very large loops in it that I'd
like to remove and use some bits of LINQ to speed things up.
The current code looks like this
foreach (Task t in db.getSubscription().Tasks)
{
if (t.TaskID == task.TaskID)
{
foreach (ReadTask rt in db.ReadTasks.ReadTasks)
{
if (rt.TaskID == task.TaskID)
{
result = true;
break;
}
}
}
}
db.getSubscription().Tasks and db.ReadTasks.ReadTasks can both be huge,
so iterating through them could take quite a while.
The LINQ I've come up with looks like this
Task t = db.getSubscription().Tasks.FirstOrDefault(s => s.TaskID ==
task.TaskID);
if (t != null)
{
ReadTask rt = db.ReadTasks.ReadTasks.FirstOrDefault(s => s.TaskID
== task.TaskID);
if (rt != null)
result = true;
}
Questions are, are these two pieces of code equivalent and should this
be FirstOrDefault or just First?
