如何使用C#代码检测系统上是否安装了.Net框架4.6.1修补程序？

using System.Management;

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Product WHERE Name = 'Microsoft .NET Framework 4.6.1'");

ManagementObjectCollection results = searcher.Get();

bool isInstalled = false;
foreach (ManagementObject obj in results)
{
    isInstalled = true;
    break;
}

if (isInstalled)
{
    Console.WriteLine(".Net Framework 4.6.1修补程序已安装。");
}
else
{
    Console.WriteLine(".Net Framework 4.6.1修补程序未安装。");
}
