Registrace sestavení zprostředkovatele na straně klienta
Poznámka:
Tato dokumentace je určená pro vývojáře rozhraní .NET Framework, kteří chtějí používat spravované třídy model UI Automation definované v System.Windows.Automation oboru názvů. Nejnovější informace o model UI Automation najdete v tématu Rozhraní API služby Windows Automation: model UI Automation.
Toto téma ukazuje, jak zaregistrovat knihovnu DLL, která obsahuje poskytovatele model UI Automation na straně klienta.
Příklad
Následující příklad ukazuje, jak zaregistrovat sestavení, které obsahuje zprostředkovatele pro okno konzoly.
using System;
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);
}
if (a != null)
{
try
{
ClientSettings.RegisterClientSideProviderAssembly(a.GetName());
}
catch (ProxyAssemblyNotLoadedException e)
{
Console.WriteLine(e.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();
}
