C # ways to traverse collections and remove elements _c# tutorial

This article illustrates how C # iterates through collections and removes elements. Share to everyone for your reference, specific as follows:

If you use foreach, it can cause an exception problem when the set that is traversed is changed.

At this point, using the for loop can effectively solve the problem.

for (int i=0;i<list.count;i++)
{
 if (condition is true)
 {
 list.remove (list[i]);
 i--
 }
}

Alternatively, store the object you want to delete with another list collection.

List<t> newlists=new list<t> ();
foreach (T-T in List)
{
 lists.add (t);
}
foreach (T t in newlists)
{
 list.remove (t);
}
