You can grab it from the Windows Registry: using System; using Microsoft.Win32;// ... public static string GetFrameworkDirectory() { // This is the location of the .Net Framework Registry Key string framworkRegPath = @"Software\Microsoft\.NetFramework"; // Get a non-writable key from the registry RegistryKey netFramework = Registry.LocalMachine.OpenSubKey(framworkRegPath, false); // Retrieve the install root path for the framework string installRoot = netFramework.GetValue("InstallRoot").ToString(); // Retrieve the version of the framework executing this program string version = string.Format(@"v{0}.{1}.{2}\", Environment.Version.Major, Environment.Version.Minor, Environment.Version.Build); // Return the path of the framework return System.IO.Path.Combine(installRoot, version); }Source (责任编辑：) |
