Registrare un assembly di provider lato client

  • Articolo

Nota

Questa documentazione è destinata agli sviluppatori .NET Framework che desiderano utilizzare le classi di UI Automation gestite definite nello spazio dei nomi System.Windows.Automation. Per informazioni aggiornate su UI Automation, vedere API di automazione di Windows: UI Automation.

Questo argomento illustra come registrare una DLL contenente provider di automazione interfaccia utente lato client.

Esempio

L'esempio seguente illustra come registrare un assembly contenente un provider per una finestra della console.

using System.Windows.Automation;
using System.Reflection;
using System.Runtime.InteropServices;
using System.IO;

namespace CSClient
{
    class CSClientProgram
    {
        [DllImport("kernel32.dll")]
        static extern IntPtr GetConsoleWindow();

        static void Main(string[] args)
        {
            // TODO  Change the path to the appropriate one for your CSProviderDLL.
            string fileloc = @"C:\SampleDependencies\CSProviderDLL.dll";
            Assembly a = null;
            try
            {
                a = Assembly.LoadFile(fileloc);
            }
            catch (FileNotFoundException e1)
            {
                Console.WriteLine(e1.Message);

                {

                }

                IntPtr hwnd = GetConsoleWindow();

                // Get an AutomationElement that represents the window.
                AutomationElement elementWindow = AutomationElement.FromHandle(hwnd);
                Console.WriteLine("Found UI Automation client-side provider for:");

                // The name property is furnished by the client-side provider.
                Console.WriteLine(elementWindow.Current.Name);
                Console.WriteLine();
            }
            Console.WriteLine("Press any key to exit.");
            Console.ReadLine();
        }
    }
