如何在局域网上启用 TCP答案

【问题描述】：

我已经为我的 WPF 应用程序编写了使用 WCF 的代码，wcf 作为 Windows 服务运行，我希望程序 wpf 在客户端计算机上运行。我在 PC 上安装了 WPF 应用程序以及服务和 sql 服务器，它在那里工作正常。但是，当我在另一台 PC 上安装 wpf 客户端时，客户端 WPF 无法连接到服务器。我的意思是 WCF windows 服务不支持局域网使用，但是我设计它只是为了这个目的。请检查我的代码并告诉我哪里出错了。

WPF 应用代码：

【解决方案1】：

在服务和客户端配置文件中，您的所有服务地址似乎都设置为 localhost。本地主机总是指运行程序的机器。

您需要为服务使用正确的机器名称并在客户端中引用它。

例如，假设您的服务托管在网络上具有以下地址的计算机上 - myservicebox:8732。服务的配置文件如下所示：

<service name="WorkMateWCF.WCFLogin">
  <endpoint address="" binding="netTcpBinding" bindingConfiguration=""
            contract="WorkMateWCF.IWCFLogin">
    <identity>
      <dns value="myservicebox" />
    </identity>
  </endpoint>
  <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
            contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://myservicbox:8732/WCFLogin" />
      </baseAddresses>
    </host>
  </service>

然后，您可以在希望使用该服务的客户中引用 net.tcp://myservicebox:8732/WCFLogin。

另外，请注意，您的服务（基于您发布的配置文件）将使用指定绑定的默认值，如果您需要不同的值（如更大的消息大小等），这可能会给您带来问题。

当您通过bindingConfiguration 属性将它们分配给客户端端点时，您的客户端配置将使用您设置的绑定。

在您的情况下不一定是问题（看起来您无论如何都在使用客户端上的默认值，一目了然），但需要注意一些事情。

感谢您的信息。我是否需要以任何方式主持此活动？我已经使用 Windows 服务项目安装了它。等待你的答复。谢谢
在 Windows 服务中托管您的 WCF 服务很好 - 这完全取决于您的需要和要求（您也可以在 IIS/WAS 下自行托管和托管）。我通常使用 IIS，但我有一项工作在 Windows 服务中托管。
我尝试将 localhost 的名称更改为 pc 名称，但是，现在您的应用程序也无法在自己的 pc 上运行。简单的更换有什么问题吗。我的程序仅适用于 10-15 台的小型网络，不适用于互联网。期待。
嗯...您可能想尝试使用机器的 IP 地址。不要忘记端口 - 例如，net.tcp://192.168.1.1:8732/WCFLogin。只需将 192.168.1.1 替换为服务所在机器的 IP 地址即可。
不确定那个 - 我必须检查一下。出于测试目的，我只需删除 DNS 值标签，看看它是否有效。

【解决方案2】：

我后来检查了事件日志，问题在于绑定时间，我将其更改为 00:10:00，它似乎可以工作，但这次我遇到了一个新错误，它与此无关问题。
