Remoting异步回调

下面是今天做的一个小试验代码：

private void FrmMain_Load(object sender, EventArgs e)

{

this.pictureBox1.Visible = false;

BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();

BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();

serverProvider.TypeFilterLevel = TypeFilterLevel.Full;

IDictionary props = new Hashtable();

//props["bindTo"] = "121.12.157.244";//"113.105.185.151";

props["port"] = 0;

HttpChannel channel = new HttpChannel(props, clientProvider, serverProvider);

ChannelServices.RegisterChannel(channel, false);

this.user = (IUser)Activator.GetObject(

typeof(IUser),

"http://localhost:9090/User.soap");

}

public delegate string MyDelegate(int a);

private MyDelegate md;

public void CallBack1(IAsyncResult Iar)

{

if (Iar.IsCompleted)

{

this.Text = md.EndInvoke(Iar);

this.pictureBox1.Visible = false;

}

private void button1_Click(object sender, EventArgs e)

{

this.Text = "";

md = new MyDelegate(this.user.GetValue);

AsyncCallback ac = new AsyncCallback(CallBack1);

IAsyncResult Iar = md.BeginInvoke(345, ac, null);

this.pictureBox1.Visible = true;

}
