Is it able to use collection expression to initialze a OrderedDictionary?

Question

Here is the introduction for OrderedDictionary.

My question is, is it able to write code something like below to initialize a OrderedDictionary?

OrderedDictionary orderedDictionary = [{"testKey1", "testValue1"}, {"testKey2", "testValue2"}];

Answer 1

This syntax seems to work in modern C#:

OrderedDictionary orderedDictionary = new( ) { { "testKey1", "testValue1" }, { "testKey2", "testValue2" } };

// or:

OrderedDictionary orderedDictionary = new( )
   {
      ["testKey1"] = "testValue1",
      ["testKey2"] = "testValue2"
   }
