.CompareTo Method (Version)
Compares the current
object to a specified Version object and returns an indication of their relative values. Version
abstract CompareTo :
value:Version -> int
override CompareTo :
value:Version -> int
Parameters value Type: System .Version
object to compare to the current Version object, or Version . a null reference ( Nothing in Visual Basic) Return Value
System .Int32 A signed integer that indicates the relative values of the two objects, as shown in the following table.
Less than zero
object is a version before Version value.
object is the same version as Version value.
Greater than zero
object is a version subsequent to Version value.
value is . a null reference ( Nothing in Visual Basic) Implements IComparable (T ) .CompareTo(T)
This method implements the
interface, and performs slightly better than the System .IComparable (T ) method because it does not have to unbox the CompareTo value parameter.
The components of
in decreasing order of importance are: major, minor, build, and revision. An unknown component is assumed to be older than any known component. For example: Version
Version 1.1 is older than version 1.1.0.
Version 1.1 is older than version 1.1.1.
Version 1.1 is older than version 18.104.22.168.
Version 1.1.2 is older than version 22.214.171.124.
Version 1.2.5 is newer than version 126.96.36.199.
The following code example demonstrates generic and nongeneric versions of the
