This is a basic question to enhance my understanding.

In a loop is the condition tokenized once and checked every time or is it calculated in every iteration?

Take this example:

for (int i = 0; i < this.TreeView1.Nodes.Count; i++)
{
}

or is it more efficient (faster) to do:

int nCount = this.TreeView1.Nodes.Count;
for (int i = 0; i < nCount; i++)
{
}

Granted, in a short loop it does not really matter as the time differences would be measured in microseconds but the principle of the thing is what I'm looking for.

Every little bit of new knowledge on .NET helps :)
