Create extension IDictionary<K, V>.GetByKey() that returns null when the key does not exist #4

The Dictionary class throws an exception when you index-access an item that does not exist.

var dictionary = new Dictionary<string, string>();
var value = dictionary["Hello"]; // throws KeyNotFoundException: The given key was not present in the dictionary

We would like a method that would return null instead of throwing an exception.
