LinkedList 

that store key/value pairs, you 

will need to supply pairs of initializers, as shown here:

SortedList lst =

  new SortedList() { {1, "One"}, {2, "Two" }, {3, "Three"} };

The compiler passes each group of values as arguments to 

Add( )

. Thus, the first pair of 

initializers is translated into a call to

 Add(1, “One”)

 by the compiler.

Because the compiler automatically calls 

Add( )

 to add initializers to a collection, 

collection initializers can be used only with collections that support a public implementation 

of

Add( )

. Therefore, collection initializers cannot be used with the
