How to get the applications installed in the system using c# code?

推荐答案

遍历注册表项SOFTWAREMicrosoftWindowsCurrentVersionUninstall"似乎给出了已安装应用程序的完整列表.

Iterating through the registry key "SOFTWAREMicrosoftWindowsCurrentVersionUninstall" seems to give a comprehensive list of installed applications.

除了下面的例子，你可以找到与我所做的类似的版本这里.

Aside from the example below, you can find a similar version to what I've done here.

这是一个粗略的例子，您可能想要做一些事情来去除提供的第二个链接中的空白行.

This is a rough example, you'll probaby want to do something to strip out blank rows like in the 2nd link provided.

string registry_key = @"SOFTWAREMicrosoftWindowsCurrentVersionUninstall";
using(Microsoft.Win32.RegistryKey key = Registry.LocalMachine.OpenSubKey(registry_key))
{
    foreach(string subkey_name in key.GetSubKeyNames())
    {
        using(RegistryKey subkey = key.OpenSubKey(subkey_name))
        {
            Console.WriteLine(subkey.GetValue("DisplayName"));
        }
    }
}

或者，您可以使用 WMI，如前所述:

Alternatively, you can use WMI as has been mentioned:

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

但这执行起来相当慢，而且我听说它可能只列出安装在ALLUSERS"下的程序，尽管这可能不正确.它还忽略了 Windows 组件 &更新，这可能对您有用.

But this is rather slower to execute, and I've heard it may only list programs installed under "ALLUSERS", though that may be incorrect. It also ignores the Windows components & updates, which may be handy for you.
