在过去的几周里,我开发了一个 64 位 WinForms 应用程序,需要与 32 位 DLL 进行通信(工作规范需要它)。
在互联网上进行了一些阅读并发现没有任何有趣的方法可以做到这一点后,我决定在我的 WinForms 应用程序中托管一个 WCF 服务应用程序来与 32 位 DLL 进行通信...或者我以为我正在做。
在开发过程中(在 Visual Studio 中运行时)它运行得非常好,但是当然,现在我需要部署,我遇到了问题。我无法对 WCF 服务有足够深入的了解,无法知道我是否以糟糕的方式处理这件事,或者我是否只是错过了一些细节。
我以管理员身份创建了该项目。开发完成后,我尝试运行 WinForm 可执行文件(调试和发布)WindowsFormsApplication1.exe。应用程序启动了,但在我尝试完成涉及使用 WCF 服务的任务后,抛出异常:
这让我相信 Visual Studio 在开发过程中托管服务,而不是 WinForm 应用程序,或者我的配置和/或目录结构不正确。

EXE所在目录:
包含 WCF 服务的目录位于上图中的 WcfService1 目录中。
我主要使用以下方法来实例化服务:
ServiceReference1.Service1Client = new ServiceReference1.SErvice1Client();
有一次我尝试切换到使用服务主机(如下),但是当我使用该方法时,每当服务尝试与 DLL 通信时就会超时。
Uri address = new Uri("http://localhost:44848/Service1.svc");
ServiceHost host = new ServiceHost(typeof(ServiceReference1.Service1Client), address);
host.Open();
然后我后来就关闭了主机。在这一点上,我愿意尝试任何事情来让它发挥作用。
[编辑] 下面是我的 WindowsFormsApplication1.exe.config 文件的代码。所有三个合约都发出警告,称它们“根据其数据类型‘clientContractType’无效”。我认为这可能是我的问题的根源,但我不知道为什么它显示此警告:

上面我已经配置了Service2,同样你也必须配置Service1和Service3。
