操作系统是 Windows Server？

Question

如何检查我的 .net 应用程序是否在 Windows 2003 Server 上运行？

因为 Buildnumber 5.2 是 Windows XP 和 Windows Server 2003。

所以我需要一张不同的支票。 有人可以帮我吗？

Answer 1

Environment.OSVersion 只为您提供与 XP 和 Server 2003 相同的内核版本，因此您无法真正区分它们。

但是，就我而言，它们支持的功能几乎相同。如果您告诉我们您为什么需要了解其中的区别、您想测试什么功能，我们或许可以提供更多帮助。

好吧，伙计们， 我编写了一些代码来检测操作系统是否是 Windows 服务器。 如果是这样，它应该返回 true：

    Private ReadOnly Property IsWindowsServer() As Boolean
    Get
        Const VER_NT_WORKSTATION As Byte = &H1
        Const VER_PRODUCT_TYPE As UInteger = &H80
        Const VER_EQUAL As Byte = 1
        Dim osvi As New OSVERSIONINFOEX()
        osvi.dwOSVersionInfoSize = CUInt(Marshal.SizeOf(osvi))
        osvi.wProductType = VER_NT_WORKSTATION
        Dim dwlConditionMask As ULong = VerSetConditionMask(0, VER_PRODUCT_TYPE, VER_EQUAL)
        Return Not VerifyVersionInfo(osvi, VER_PRODUCT_TYPE, dwlConditionMask)
    End Get
End Property

<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Ansi)> _
Structure OSVERSIONINFOEX
    Public dwOSVersionInfoSize As Integer
    Public dwMajorVersion As Integer
    Public dwMinorVersion As Integer
    Public dwBuildNumber As Integer
    Public dwPlatformId As Integer
    <MarshalAs(UnmanagedType.ByValTStr, SizeConst:=128)> _
    Public szCSDVersion As String
    Public wServicePackMajor As UInt16
    Public wServicePackMinor As UInt16
    Public wSuiteMask As UInt16
    Public wProductType As Byte
    Public wReserved As Byte
End Structure

<DllImport("kernel32.dll")> _
Private Function VerSetConditionMask(dwlConditionMask As ULong, dwTypeBitMask As UInteger, dwConditionMask As Byte) As ULong
End Function

<DllImport("kernel32.dll")> _
Private Function VerifyVersionInfo(<[In]> ByRef lpVersionInfo As OSVERSIONINFOEX, dwTypeMask As UInteger, dwlConditionMask As ULong) As Boolean
End Function

我需要有人可以在不同的 Windows 服务器上检查它并检查它是否返回 true。 如果您测试，请在此处填写 OS-Server Build Number 或 Name，以便我知道它是否适用于不同版本 ^^

你可以这样检查：

MsgBox(IsWindowsServer())

执行此 IMO 的最佳方法是使用 WMI。 Win32_OperatingSystem 类包含一个属性 ProductType，对于工作站操作系统，该属性为 1，对于服务器操作系统，该属性为 2 或 3。

我不擅长VB.NET，也许其他人可以为你转换这个C#：

public static bool IsServerOS()
{
    return IsServerOS(Environment.MachineName);
}
public static bool IsServerOS(string computerName)
{
    ConnectionOptions options = new ConnectionOptions() { EnablePrivileges = true, Impersonation = ImpersonationLevel.Impersonate };
    ManagementScope scope = new ManagementScope(string.Format(@"\\{0}\root\CIMV2", computerName), options);
    ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");

    using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query))
    using (ManagementObjectCollection results = searcher.Get())
    {
        if (results.Count != 1) throw new ManagementException();

        uint productType = (uint)results.OfType<ManagementObject>().First().Properties["ProductType"].Value;

        switch (productType)
        {
            case 1:
                return false;
            case 2:
                return true;
            case 3:
                return true;
            default:
                throw new ManagementException();
        }
    }
}
