我有一类称为MyServiceHost.vb：

I have a class called MyServiceHost.vb:

public class MyServiceHost : ServiceHost
{
    private Dictionary<int, Service> _activeClients;

    public event EventHandler<MessageReceivedEventArgs> MessageReceived;
}

之后以另一种形式我想在我的其他形式，我定义这些行的第二行：

After that in another form I want to have the second line in my other form I defined these lines:

_host = new MyServiceHost(typeof(Service));
            _host.MessageReceived += new EventHandler<MessageReceivedEventArgs>(_host_MessageReceived);
            _host.Open();

如何把它们写在Vb.net请大家帮忙，以下似乎不工作：

How to write them in Vb.net please help, the followings does not seem to work:

_host = New MyServiceHost(GetType(Service))
    _host. += New EventHandler(Of MessageReceivedEventArgs)(AddressOf _host_messageRecieved)

另外请注意，我MyServiceHost.vb类看起来是这样的：

Also note that my MyServiceHost.vb class looks like this:

Dim _activeClients As Dictionary(Of Integer, Service)
Public Event MessageReceived As EventHandler(Of MessageReceivedEventArgs)

什么是错的？

What is wrong?

推荐答案

请尝试使用：

AddHandler _host.MessageReceived, AddressOf _host_messageRecieved
