// Declares a class member for each structure element.

    [ StructLayout( LayoutKind.Sequential )]
    public class SystemTime
    {
       public ushort year;
       ...
       public ushort milliseconds;
    }

    public class LibWrap
    {
      // Declares a managed prototype for the unmanaged function.
      [ DllImport( "Kernel32.dll" )]
      public static extern void GetSystemTime( [In,Out] SystemTime st );
    }

[VB.net]

  Imports System.Runtime.InteropServices

  'Declare Sructure for SytemTime so you can access all parts
  <StructLayout(LayoutKind.Sequential)> _
    Public Structure SYSTEMTIME
    Public wYear As Short
    Public wMonth As Short
    Public wDayOfWeek As Short
    Public wDay As Short
    Public wHour As Short
    Public wMinute As Short
    Public wSecond As Short
    Public wMilliseconds As Short
    End Structure

    'Declare Sub to call GetSystemTime
    Private Declare Sub GetSystemTime Lib "kernel32" Alias "GetSystemTime" (ByRef lpSystemTime As SYSTEMTIME)

    'Test It
    Private Sub Test()
    Dim sysTime As SYSTEMTIME
    GetSystemTime(sysTime)
    MessageBox.Show(sysTime.wMilliseconds.ToString())
    End Sub
