Question

我在VB.Net中有以下代码。它可以根据需要进行编译和工作。

在我努力转向C＃时，每当我开始一个新项目时，我都会努力使用C＃，但在这种情况下，我显然遗漏了一些东西。

Private m_Service As ServiceHost = Nothing

Public Function Start(ByVal AddressToConnect As String) As Thread
    Dim ServerProcess As New Thread(AddressOf WebService)

    ServerProcess.Start(AddressToConnect)

    Return ServerProcess
End Function

Private Sub WebService(ByVal AddressToListen As String) ' Address should be in the form: "http://localhost:8000/IHello"
    ' Define where to listen
    Dim Address As Uri = New Uri(AddressToListen)
    ' Define how to exchange messages
    Dim Binding As BasicHttpBinding = New BasicHttpBinding()

    ' When the connection is established, define what object is created
    m_Service = New ServiceHost(GetType(Worker), Address)

    ' Add an endpoint, passing the address, binding and contract
    m_Service.AddServiceEndpoint(GetType([Interface].IContract), Binding, Address)

    ' YOU MUST PERFORM THE FOLLOWING BEFORE YOU ATTEMPT TO OPEN THE CONNECTION
    ' netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user

    ' Begin listening for connections
    m_Service.Open()
    Console.WriteLine("WCF Service started")
End Sub

Public Sub [Stop]()
    m_Service.Close()
    m_Service = Nothing
End Sub

从p到其中一个VB到C＃转换站点的C＃中说同样如下：

private ServiceHost _Service = null;

public Thread Start(string AddressToConnect)
{

    Thread ServerProcess = new Thread(new EventHandler(WebService));
    ServerProcess.Start(AddressToConnect);
    return ServerProcess;
}


private void WebService(string AddressToListen)
{
    //  Address should be in the form: "http://localhost:8000/IHello"
    //  Define where to listen
    Uri Address = new Uri(AddressToListen);
    //  Define how to exchange messages

    BasicHttpBinding Binding = new BasicHttpBinding();

    //  When the connection is established, define what object is created
    _Service = new ServiceHost(typeof(Worker), Address);

    //  Add an endpoint, passing the address, binding and contract
    _Service.AddServiceEndpoint(typeof(Interface.IContract), Binding, Address);

    //  YOU MUST PERFORM THE FOLLOWING BEFORE YOU ATTEMPT TO OPEN THE CONNECTION
    //  netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user

    //  Begin listening for connections
    _Service.Open();
    Console.WriteLine("WCF Service started");
}

public void Stop()
{
    _Service.Close();
    _Service = null;
}

问题是编译器抱怨： Thread ServerProcess = new Thread（new EventHandler（WebService））;

＆＃34; WebService没有重载匹配委托EventHandler＆＃34;

我做错了什么？ C＃代码应该是什么？

道歉应该是一个简单的问题，但我一直都在与代表们争吵。

感谢Markus，这就是我现在所拥有的：

public Thread Start(string AddressToConnect)
    {
        Thread ServerProcess = new Thread(WebService);

        ServerProcess.Start(AddressToConnect);

        return ServerProcess;
    }

WebService方法现在是：

private void WebService(object AddressToListen)
    {
        //  Address should be in the form: "http://localhost:8000/IHello"
        //  Define where to listen
        Uri Address = new Uri((string)AddressToListen);
        //  Define how to exchange messages
...

Answer 1

您可以删除AddressOf运算符。 C＃中不需要它：

Thread ServerProcess = new Thread(WebService);

有一点需要注意的是，提供的方法需要匹配ParameterizedThreadStart的签名。这会将对象作为参数，因此您需要更改WebService方法的签名：

private void WebService(object AddressToListen)

在该方法中，您必须将对象转换为字符串。
