使用 .net 从戴尔计算机获取服务标签？

Question

我有一个提取模型信息（硬件信息）的类 本地机器代码如下所示：

   Imports System.Management

Public Class clsWMI
    Private objOS As ManagementObjectSearcher
    Private objCS As ManagementObjectSearcher
    Private objMgmt As ManagementObject
    Private m_strComputerName As String
    Private m_strManufacturer As String
    Private m_StrModel As String
    Private m_strOSName As String
    Private m_strOSVersion As String
    Private m_strSystemType As String
    Private m_strTPM As String
    Private m_strWindowsDir As String


    Public Sub New()

        objOS = New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
        objCS = New ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem")
        For Each objMgmt In objOS.Get


            m_strOSName = objMgmt("name").ToString()
            m_strOSVersion = objMgmt("version").ToString()
            m_strComputerName = objMgmt("csname").ToString()
            m_strWindowsDir = objMgmt("windowsdirectory").ToString()
        Next

        For Each objMgmt In objCS.Get
            m_strManufacturer = objMgmt("manufacturer").ToString()
            m_StrModel = objMgmt("model").ToString()
            m_strSystemType = objMgmt("systemtype").ToString
            m_strTPM = objMgmt("totalphysicalmemory").ToString()
        Next
    End Sub

    Public ReadOnly Property ComputerName()
        Get
            ComputerName = m_strComputerName
        End Get

    End Property
    Public ReadOnly Property Manufacturer()
        Get
            Manufacturer = m_strManufacturer
        End Get

    End Property
    Public ReadOnly Property Model()
        Get
            Model = m_StrModel
        End Get

    End Property
    Public ReadOnly Property OsName()
        Get
            OsName = m_strOSName
        End Get

    End Property

    Public ReadOnly Property OSVersion()
        Get
            OSVersion = m_strOSVersion
        End Get

    End Property
    Public ReadOnly Property SystemType()
        Get
            SystemType = m_strSystemType
        End Get

    End Property
    Public ReadOnly Property TotalPhysicalMemory()
        Get
            TotalPhysicalMemory = m_strTPM
        End Get

    End Property

    Public ReadOnly Property WindowsDirectory()
        Get
            WindowsDirectory = m_strWindowsDir
        End Get

    End Property

End Class

有可能从 WMI 获取服务标签吗？从客户端表单中，我显示如下值：

   Dim objWMI As New clsWMI()
        With objWMI
            Debug.WriteLine("Computer Name = " & .ComputerName)
            Me.Label1.Text = "Name: " & .ComputerName
            Debug.WriteLine("Computer Manufacturer = " & .Manufacturer)
            Me.Label2.Text = "Manufacturer: " & .Manufacturer
            Debug.WriteLine("Computer Model = " & .Model)
            Me.Label3.Text = "Model: " & .Model
            Debug.WriteLine("OS Name = " & .OsName)
            Me.Label4.Text = "OS Name: " & .OsName
            Debug.WriteLine("OS Version = " & .OSVersion)
            Me.Label5.Text = "OS VERSION: " & .OSVersion

            Debug.WriteLine("System Type = " & .SystemType)
            Me.Label6.Text = "System type = " & .SystemType

            Debug.WriteLine("Total Physical Memory = " & .TotalPhysicalMemory)
            Me.Label7.Text = "Memory: " & .TotalPhysicalMemory
            Debug.WriteLine("Windows Directory = " & .WindowsDirectory)
            Me.Label8.Text = "Win Directory: " & .WindowsDirectory
        End With

Answer 1

我认为您需要从 BIOS 中获取序列号，如下所示：

Select SerialNumber From Win32_BIOS

在戴尔上，我相信这对应于服务标签

Answer 2

这是一些应该得到它的 C# 代码，

我从 获取Win32_ComputerSystem 但如果您愿意，可以轻松地将其转换为再次运行 Win32_Bios

void GetComputerSystem()
{
        // http://msdn.microsoft.com/en-us/library/aa394102(VS.85).aspx
        ManagementObjectCollection oReturnCollection;
        try
        {
            ObjectQuery query = new ObjectQuery("Select UserName,Name,Manufacturer,Model from Win32_ComputerSystem");
            ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(gManager, query);
            oReturnCollection = oSearcher.Get();
            oSearcher.Dispose();
        }
        catch
        {
            gHasError = true;
            return;
        }

        //loop through found drives and write out info
        foreach (ManagementObject oReturn in oReturnCollection)
        {
        // Disk name  
            object oLoggedInUser = oReturn["UserName"];
            if (oLoggedInUser == null)
                gOSInfo.UserName = "None";
            else
                gOSInfo.UserName = (string)oLoggedInUser;

            string Manufacturer = (string)oReturn["Manufacturer"];
            string Model = (string)oReturn["Model"];
        }
    }
}

Answer 3

我编写了一个程序，用于恢复戴尔服务标签、快速代码以及驱动程序和保修信息的链接。 找到 C# 代码
