OperatingSystem.ToString Method

public:
 override System::String ^ ToString();

public override string ToString ();

override this.ToString : unit -> string

Public Overrides Function ToString () As String

Returns

The string representation of the values returned by the Platform, Version, and ServicePack properties.

Examples

The following code example illustrates the use of the ToString method to display OperatingSystem objects.

// Example for the OperatingSystem constructor and the 
// OperatingSystem::ToString( ) method.
using namespace System;

// Create and display an OperatingSystem object.
void BuildOSObj( PlatformID pID, Version^ ver )
{
   OperatingSystem^ os = gcnew OperatingSystem( pID,ver );
   Console::WriteLine( "   {0}", os->ToString() );
}

void BuildOperatingSystemObjects()
{
   
   // The Version object does not need to correspond to an 
   // actual OS version.
   Version^ verNull = gcnew Version;
   Version^ verMajMin = gcnew Version( 3,11 );
   Version^ verMMBld = gcnew Version( 5,25,625 );
   Version^ verMMBVer = gcnew Version( 5,6,7,8 );
   Version^ verString = gcnew Version( "3.5.8.13" );
   
   // All PlatformID members are shown here.
   BuildOSObj( PlatformID::Win32NT, verNull );
   BuildOSObj( PlatformID::Win32S, verMajMin );
   BuildOSObj( PlatformID::Win32Windows, verMMBld );
   BuildOSObj( PlatformID::WinCE, verMMBVer );
   BuildOSObj( PlatformID::Win32NT, verString );
}

int main()
{
   Console::WriteLine( "This example of the OperatingSystem constructor and \n"
   "OperatingSystem::ToString( ) generates the following "
   "output.\n" );
   Console::WriteLine( "Create and display several different "
   "OperatingSystem objects:\n" );
   BuildOperatingSystemObjects();
   Console::WriteLine( "\nThe OS version of the host computer is:\n\n   {0}", Environment::OSVersion->ToString() );
