Add()
instance.Add(key, value)
Adds an element with the specified key and value into the MfDictionaryBase instance.
key
The key of the element to add.
value
The value of the element to add.
Throws MfNullReferenceException if MfDictionaryBase is not set to an instance.
Throws MfNotSupportedException if the MfDictionaryBase is read-only or The MfDictionaryBase has a fixed size.
Throws MfNotSupportedException if key is an object and does not derive from MfObject
Throws MfArgumentNullException if key is null.
An object that has no correlation between its state and its hash code value should typically not be used as the key.
You can also use the Item property to add new elements by setting the value of a key that does not exist in the MfDictionaryBase; for example,
myCollection.Item["myNonexistentKey"] = myValue.
However, if the specified key already exists in the MfDictionaryBase, setting the Item property overwrites the old value. In contrast, the Add method does not modify existing elements.
