Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

public static class StructuralComparisons

The StructuralComparisons type exposes the following members.

  NameDescription
Public propertyStatic memberStructuralComparerGets a predefined object that performs a structural comparison of two objects.
Public propertyStatic memberStructuralEqualityComparerGets a predefined object that compares two objects for structural equality.
Top

The StructuralComparisons class returns the following two predefined comparison objects:

  • An IComparer implementation that can be passed to a method such as Array.IStructuralComparable.CompareTo(Object, IComparer) or Tuple<T1, T2, T3>.IStructuralComparable.CompareTo(Object, IComparer) to perform a structural comparison of two objects. It is designed to indicate whether the first object precedes, follows, or occurs in the same position as the second object in the sort order.

  • An IEqualityComparer implementation that can be passed to a method such as Array.IStructuralEquatable.Equals(Object, IEqualityComparer) or Tuple<T1, T2, T3>.IStructuralEquatable.Equals(Object, IEqualityComparer) to perform a comparison for structural equality.

The objects can be used to perform a structural comparison or a structural equality comparison of two collection objects, such as array or tuple objects. In structural comparison, two objects are compared based on their values. Objects can be ordered based on some criteria, and two objects are considered equal when they have equal values, not because they reference the same physical object
