OperatingSystem Class
Represents information about an operating system, such as the version and platform identifier.
For a list of all members of this type, see OperatingSystem Members.

[Visual Basic] <Serializable> NotInheritable Public Class OperatingSystem Implements ICloneable [C#] [Serializable] public sealed class OperatingSystem : ICloneable [C++] [Serializable] public __gc __sealed class OperatingSystem : public ICloneable [JScript] public Serializable class OperatingSystem implements ICloneable
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
This class provides a method to copy an instance of OperatingSystem, and a method to return a string representation of operating system information.
Example
[Visual Basic, C#, C++] The following code example creates objects of the OperatingSystem class with selected values for the Platform and Version properties.
