To use Collection Initializer syntax, we require two items to be true. The type must: Implement the IEnumerable pattern, which can be either the IEnumerable interface or simply have a GetEnumerator method. This may be referred to as "duck" typing: if it looks like a duck and quacks like ...
When you create an anonymous type that contains an array, the array must be implicitly typed in the type's object initializer. In the following example,contactsis an implicitly typed array of anonymous types, each of which contains an array namedPhoneNumbers. Thevarkeyword isn't used inside th...
