Int64RangePartitionInformation - how can I create object? I want to use object in my unit test

Question

Int64RangePartitionInformation - how can I create object? I want to use object in my unit test. When I attempt to create object using var c = new Int64RangePartitionInformation(); compiler throws me error 'Int64RangePartitionInformation' does not contain a constructor that takes 0 arguments"

I don't see any constructor for this class either. How this type of non-instantiable class is implemented? If I want to , how can i instantiate it?

One solution, although not very nice, is:

FormatterServices.GetUninitializedObject(
    typeof(Int64RangePartitionInformation)) as Int64RangePartitionInformation;

Since you're testing, you could create a mock and use that. For instance with Moq, you could do

var partitionInformation = new Mock<Int64RangePartitionInformation>().Object;
DoSomething(partitionInformation);

Int64RangePartitionInformation is sealed so that won't work. – jamesmus Feb 28 '18 at 15:06
