使用 C# 获取已安装的软件列表答案

【问题标题】：Get installed software list using C#使用 C# 获取已安装的软件列表
【发布时间】：2014-07-23 11:20:14
【问题描述】：

我尝试获取已安装应用程序密钥的列表：

RegistryKey RegKeyUninstallList = Registry.LocalMachine;
string strUninstallList = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
string[] test = RegKeyUninstallList.OpenSubKey(strUninstallList).GetSubKeyNames();

我只从以下位置获取密钥：

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

但我还需要以下密钥：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

我的程序应该能够在64Bit 和32Bit 机器上运行。

编辑：好的，我已经尝试过 Check if application is installed in registry 和来自 tHiNk_OuT_oF_bOx 的解决方案。

但问题没有解决！

问题是我得到了完全相同的 test 和 test2 列表：

RegistryKey RegKeyUninstallList = Registry.LocalMachine;
string strUninstallList = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
string strUninstallList2 = @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall";
string[] test = RegKeyUninstallList.OpenSubKey(strUninstallList).GetSubKeyNames();
string[] test2 = RegKeyUninstallList.OpenSubKey(strUninstallList2).GetSubKeyNames();

您不应该改用 WMI 吗？ technet.microsoft.com/en-us/library/ee156540.aspx

解决方法是在注册表中搜索3个地方：

在 CurrentUser 中的 SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
在 LocalMachine 中安装 SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\在 LocalMachine 中卸载

下面的代码适合你的需要。

public static bool IsApplicationInstalled(string p_name)
{
    string displayName;
    RegistryKey key;

    // search in: CurrentUser
    key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall");
    foreach (String keyName in key.GetSubKeyNames())
    {
        RegistryKey subkey = key.OpenSubKey(keyName);
        displayName = subkey.GetValue("DisplayName") as string;
        if (p_name.Equals(displayName, StringComparison.OrdinalIgnoreCase) == true)
        {
            return true;
        }
    }

    // search in: LocalMachine_32
    key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall");
    foreach (String keyName in key.GetSubKeyNames())
    {
        RegistryKey subkey = key.OpenSubKey(keyName);
        displayName = subkey.GetValue("DisplayName") as string;
        if (p_name.Equals(displayName, StringComparison.OrdinalIgnoreCase) == true)
        {
            return true;
        }
    }

    // search in: LocalMachine_64
    key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall");
    foreach (String keyName in key.GetSubKeyNames())
    {
        RegistryKey subkey = key.OpenSubKey(keyName);
        displayName = subkey.GetValue("DisplayName") as string;
        if (p_name.Equals(displayName, StringComparison.OrdinalIgnoreCase) == true)
        {
            return true;
        }
    }

    // NOT FOUND
    return false;
}

【讨论】：

不要使用Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node...")。请改用RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, is64bit ? RegistryView.Registry64 : RegistryView.Registry32); ;)
@Xaruth 谢谢，它适用于 `´RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, is64bit ? RegistryView.Registry64 : RegistryView.Registry32)´
请求的注册表访问不允许:(请提供任何解决方案？
@Xaruth 当我们使用您的代码时，它会显示安全异常

看来你现在必须使用 OpenBaseKey，我正在使用代码：

List<string> gInstalledSoftware
        void GetInstalledSoftwareList()
        {
            string displayName;

            using (RegistryKey key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", false))
            {                
                foreach (String keyName in key.GetSubKeyNames())
                {
                    RegistryKey subkey = key.OpenSubKey(keyName);
                    displayName = subkey.GetValue("DisplayName") as string;
                    if (string.IsNullOrEmpty(displayName))
                        continue;

                    gInstalledSoftware.Add(displayName.ToLower());
                }
            }

            //using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", false))
            using (var localMachine = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))
            {
                var key = localMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", false);
                foreach (String keyName in key.GetSubKeyNames())
                {
                    RegistryKey subkey = key.OpenSubKey(keyName);
                    displayName = subkey.GetValue("DisplayName") as string;
                    if (string.IsNullOrEmpty(displayName))
                        continue;

                    gInstalledSoftware.Add(displayName.ToLower());
                }
            }

            using (var localMachine = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32))
            {
                var key = localMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", false);
                foreach (String keyName in key.GetSubKeyNames())
                {
                    RegistryKey subkey = key.OpenSubKey(keyName);
                    displayName = subkey.GetValue("DisplayName") as string;
                    if (string.IsNullOrEmpty(displayName))
                        continue;

                    gInstalledSoftware.Add(displayName.ToLower());
                }
            }

            using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall",false))
            {
                foreach (String keyName in key.GetSubKeyNames())
                {
                    RegistryKey subkey = key.OpenSubKey(keyName);
                    displayName = subkey.GetValue("DisplayName") as string;
                    if (string.IsNullOrEmpty(displayName))
                        continue;

                    gInstalledSoftware.Add(displayName.ToLower());
                }
            }             
        }

所有答案都无法检索 Windows 10 上每个已安装的应用程序。以上代码仅显示最常用的已安装应用程序并非所有已安装应用程序。所以我找到了这个解决方案：

string appPATH = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
            using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(appPATH))
            {
                foreach (string skName in rk.GetSubKeyNames())
                {
                    using (RegistryKey sk = rk.OpenSubKey(skName))
                    {
                        try
                        {

                            //Get App Name
                            var displayName = sk.GetValue("DisplayName");
                            //Get App Size
                            var size = sk.GetValue("EstimatedSize");

                            string item;
                            if (displayName != null)
                            {
                                if (size != null)
                                    item = displayName.ToString();
                                else
                                {
                                    item = displayName.ToString();
                                    if (item.Contains(""))
                                    MessageBox.Show(displayName.ToString());

                                }

                            }
                        }
                        catch (Exception ex)
                        { }
                    }
                }

            }

我使用了这段代码，它有点抽象，它会检查 32/64 位操作系统。为了简单起见，它还使用了 C#V8 功能。

public static bool CheckAppInstallation(string programName)
{
    bool result = false;
    string uninstallKey1 = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
    string uninstallKey2 = @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall";
    result |= CheckInAddress(uninstallKey1, RegistryHive.LocalMachine, programName);
    result |= CheckInAddress(uninstallKey1, RegistryHive.CurrentUser, programName);
    result |= CheckInAddress(uninstallKey2, RegistryHive.LocalMachine, programName);
    return result;

    static bool CheckInAddress(string address, RegistryHive hive, string programName)
    {
        var view = Environment.Is64BitOperatingSystem ? RegistryView.Registry64 : RegistryView.Registry32;
        using var localKey = RegistryKey.OpenBaseKey(hive, view).OpenSubKey(address);
        foreach (var subKey in localKey.GetSubKeyNames().Select(keyName => localKey.OpenSubKey(keyName)))
            if (subKey.GetValue("DisplayName") is string displayName && displayName.Contains(programName))
                return true;
        return false;
    }
}

using Microsoft.VisualBasic;??
只是在 vb.net 中做并转换为 c# 这就是原因

【解决方案6】：

您能否尝试在您的项目中添加引用“System.Management”并在使用此代码后：

我觉得更容易

ManagementObjectSearcher mos = new ManagementObjectSearcher("SELECT * FROM Win32_Product");
foreach (ManagementObject mo in mos.Get())
{
     Console.WriteLine(mo["Name"]);
}

您好，这将仅返回 Microsoft 的已安装产品列表，而不是全部。
