静默卸载远程计算机上的应用程序

Question

我正在开发一个C#程序来远程卸载应用程序。它工作得很好，但问题是它没有列出特定选定计算机上安装的所有产品。

使用WMI列出已安装产品的代码为：

void ListAllProducts()
{
    try
    {
        ConnectionOptions connection = new ConnectionOptions();
        connection.Username = Connect.UserName;
        connection.Password = Connect.Password;
        connection.Authority = "ntlmdomain:MSHOME";

        ManagementScope scope = new ManagementScope("\\\\"+ Connect.MachineName +"\\root\\CIMV2", connection);
        scope.Connect();

        ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_Product");

        ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
        System.Threading.Thread.Sleep(5000);

        foreach (ManagementObject queryObj in searcher.Get())
        {
            listBox4.Items.Add(queryObj["Name"].ToString());
            listBox2.Items.Add (queryObj["Name"].ToString ());
            listBox1.Items.Add(queryObj["IdentifyingNumber"].ToString());
            listBox3.Items.Add(queryObj["Version"].ToString());
        }
    }
    catch (ManagementException e)
    {
        MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
    }
}

卸载所有产品的代码为：

void UninstallProduct()
{
    try
    {
        ConnectionOptions connection = new ConnectionOptions();
        connection.Username = Connect.UserName;
        connection.Password = Connect.Password;
        connection.Authority = "ntlmdomain:MSHOME";

        ManagementScope scope = new ManagementScope("\\\\"+Connect.MachineName +"\\root\\CIMV2", connection);
        scope.Connect();

        ManagementObject classInstance = new ManagementObject(scope, new ManagementPath ("Win32_Product.IdentifyingNumber='"+listBox1.Text +"',Name='"+listBox2.Text+"',Version='"+ listBox3.Text+"'"),null);

        // no method in-parameters to define

        // Execute the method and obtain the return values.
        ManagementBaseObject outParams = 
            classInstance.InvokeMethod("Uninstall", null, null);

        // List outParams
       MessageBox.Show ("Uninstallation Starts");
    }
    catch(ManagementException err)
    {
        MessageBox.Show("An error occurred while trying to execute the WMI method: " + err.Message);
    }
}

请帮助我列出所选计算机上安装的所有产品，并在未经所选计算机的用户同意的情况下卸载它。

我相信您的问题与了解远程计算机上安装了哪些应用程序有关。一旦你知道了这一点，你就可以使用你的代码来卸载它们了。在这种情况下，下面是一篇关于如何列出远程计算机上的所有应用程序(及其卸载信息)的文章的链接：

Windows Win32_Product仅表示由Windows Installer安装的产品。要获取所有已安装产品的列表，您需要枚举SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall注册表项的子项。要远程执行此操作，您可以使用WMI注册表类StdRegProv类。TechNet包括一些示例脚本，这些脚本展示了如何实现这一点，以及您可以根据自己的特定需求调整哪些脚本：
