C # limited Dictionary

Question

I want to build a dictionary (key, value), but I want this dictionary to have a limited size, for example 1000 entries, so when I am rich with this limit size, I want to delete the first element and add a new element (FIFO).

I want to use a dictionary because I am always looking for keys in a dictionary (I need it to be fast)

How to do it?

Answer 1

To get both the dictionary and the LIFO / FIFO behavior (to delete the newest / oldest record), you can use OrderedDictionary. See http://msdn.microsoft.com/en-us/library/system.collections.specialized.ordereddictionary.aspx .

if(myDic.Count == MAXCOUNT - 1)
{
    myDic.Remove(myDic[0]);
}
myDic.Add(key, item);

I solved the problem by typing one method that checks the number of dictionaries manually, and when its size exceeds a certain limit, it will delete some entries from the dictionary.
