mscorlib 2.0.0.0 4.0.0.0 Contravariant To be added.

Defines generalized comparison methods that a value type or class implements to create a type-specific comparison method.

This interface is implemented by types whose values can be ordered; for example, the numeric and string classes.

- Method
  System.Int32 `` To be added.

  Returns the sort order of the current instance compared to the specified object.

  A value that reflects the sort order of the current instance as compared to . The following table defines the conditions under which the returned value is a negative number, zero, or a positive number.

  Returned Value
  Description
  A negative value
  The current instance is < .
  Zero
  The current instance is == .
  A positive value
  The current instance is > than .

  For any objects A, B and C, the following are required to be true:

  A.CompareTo(A) is required to return zero.

  If A.CompareTo(B) returns zero then B.CompareTo(A) is required to return zero.

  If A.CompareTo(B) is zero, then B.CompareTo(C) and A.CompareTo(C) must have the same sign (negative, zero or positive).

  If B.CompareTo(C) is zero, then A.CompareTo(B) and A.CompareTo(C) must have the same sign (negative, zero or positive).

  If A.CompareTo(B) returns zero and B.CompareTo(C) returns zero then A.CompareTo(C) is required to return zero.

  If A.CompareTo(B) returns a value other than zero then B.CompareTo(A) is required to return a value of the opposite sign.

  If A.CompareTo(B) returns a value not equal to zero, and B.CompareTo(C) returns a value of the same sign as , then A.CompareTo(C) is required to a value of the same sign as and .

  The exact behavior of this method is unspecified. The intent of this method is to provide a mechanism that orders instances of a class in a manner that is consistent with the mathematical definitions of the relational operators (<, >, and ==), without regard for class-specific definitions of the operators.

  Use the method to determine the ordering of instances of a class.
