my Dictionary removal code correct?
I want to iterator a Dictionary variable instance, and remove all elements under a specific condition.
Here is my code. My questions about whether the following solution will function correctly?
1. will dic.Remove(key) operation impact keys collection?
2. will dic.Remove(key) operation impact dic[key] operation?
I have such concern is because I heard while interation in the middle, remove any elements inside the Dictionary is dangerous because it will make some reference invalid and impact result. Any ideas?
Dictionary<string, Foo>.KeyCollection keys = dic.Keys;
foreach (string key in keys)
// order is a public property of Foo class
if (dic[key].order > 100)
// will keys collection variable be impacted if we remove here?
// will dic[key] operation also be impacted?
thanks in advance,
