Modifying A Collection While Iterating Through It

Has anyone a nice pattern to allow me to get around the inability to remove objects while I loop through an enumerable collection (eg, an IList or KeyValuePairs in a dictionary)

For example, the following fails, as it modifies the List being enumerated over during the foreach

foreach (MyObject myObject in MyListOfMyObjects)
{
     if (condition) MyListOfMyObjects.Remove(myObject);
}

In the past I have used two methods.

I have replaced the foreach with a reversed for loop (so as not to change the any indexes I am looping over if I remove an object).

I have also tried storing a new collection of objects to remove within to loop, then looping through that collection and removed the objects from the original collection.

These work fine, but neither feels nice, and I was wondering if anyone has come up with a more elegant solution to the issue
