我正在使用 WCF 服务库创建 Windows 服务,用于在 PIC32 微控制器和 Windows 平台之间开发基于 TCP 的通信以发送和接收数据。
我的 app.config 文件是
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's
app.config file. System.Configuration does not support config files for libraries. -->
<system.serviceModel>
<services>
<service behaviorConfiguration="WcfServiceLibrary1.Service1Behavior" name="WcfServiceLibrary1.Service1">
<endpoint address="" binding="netTcpBinding" bindingConfiguration=""
contract="WcfServiceLibrary1.IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8523/Service1" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WcfServiceLibrary1.Service1Behavior">
<serviceMetadata httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
而 C# Codefor service1.cs 文件是
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.ServiceModel;
using WcfServiceLibrary1;
namespace WindowsService1
{
public partial class Service1 : ServiceBase
{
internal static ServiceHost myServiceHost = null;
public WCFServiceHost1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
if (myServiceHost != null)
{
myServiceHost.Close();
}
myServiceHost = new ServiceHost(typeof(Service1));
myServiceHost.Open();
}
protected override void OnStop()
{
if (myServiceHost != null)
{
myServiceHost.Close();
myServiceHost = null;
}
}
}
}
现在我在public WCFServiceHost1()
那个Method must have a return type中遇到错误。
我不明白为什么会出现此错误。我现在在 WCF 中,我通过 msdn 中提供的信息做到了这一点。
