Version Constructor (String)

Initializes a new instance of the Version class using the specified string.

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

public Version(
	string version
)

Parameters

version
Type: System.String

A string containing the major, minor, build, and revision numbers, where each number is delimited with a period character ('.').

ExceptionCondition
ArgumentException

version has fewer than two components or more than four components.

ArgumentNullException

version is null.

ArgumentOutOfRangeException

A major, minor, build, or revision component is less than zero.

FormatException

At least one component of version does not parse to an integer.

OverflowException

At least one component of version represents a number greater than MaxValue.

The version parameter can contain only the components major, minor, build, and revision, in that order, and all separated by periods. There must be at least two components, and at most four. The first two components are assumed to be major and minor. The value of unspecified components is undefined.

The format of the version number is as follows. Optional components are shown in square brackets ('[' and ']'):

major.minor[.build[.revision]]

All defined components must be integers greater than or equal to 0. For example, if the major number is 6, the minor number is 2, the build number is 1, and the revision number is 3, then version should be "6.2.1.3".
