As it was implemented, you compare collections using IStructuralComparable, which requires you to pass in an IComparer to use in comparing individual elements from the two structures.

. The best example of this is arrays, which with .NET 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:

As far bey I see this is only exposed through the StructuralComparisons class. The only way I emanet figure out to make this useful is to make C# StructuralComparisons Nedir a StructuralEqualityComparer helper class as follow:

The PopulationComparer class provides an IComparer implementation that allows the array of sextuples to be sorted by any one of its components. Two values are provided to the PopulationComparer class in its constructor: the position of the component that defines the sort order, and C# StructuralComparisons Kullanımı a Boolean value that indicates whether the tuple objects should be sorted in ascending or descending order.
