Shows how to enable use of a collection initializer by including an Add method in a collection class that implements IEnumerable. How to: Create a Collection Used by a Collection Initializer Shows how to create an extension method called Add that can be used to populate a collection with values from a collection initializer. How to: Create an Add Extension Method Used by a Collection Initializer Deeper levels of nesting are treated as array literals and the nested value lists are not matched to the Add method of any collection. Only nested value lists from the first level of nesting are sent to the Add method for the collection type. Dim days = New Dictionary(Of Integer, String)
The previous code example is equivalent to the following code. Dim days = New Dictionary(Of Integer, String) From Each of the nested value lists is matched to the Add method for the Dictionary. For example, the following code example creates a Dictionary in which the keys are of type Integer and the values are of type String. When you create a collection by using nested values, each element of the nested value list is passed as an argument to the Add method that matches the element types.
