使用 WCF 和 .NET 4.0 在 C# 中实现 SOAP 客户端 [英] Implementing a SOAP client in C# with WCF and .NET 4.0

问题描述

我在 .NET 4.0 中开始使用 WCF 时遇到问题.这是我的情况:

I'm having trouble getting started with WCF in .NET 4.0. This is my situation:

我用 PHP 创建了一个小型 SOAP 服务器.我有一个 C# 项目，我想在其中连接到此服务器并启动 SOAP 通信.

I have created a small SOAP Server in PHP. I have a C# project in which I want to connect to this Server and initiate the SOAP communication.

我的问题是，我不知道如何在 C# 中做到这一点.我找不到正确的 WCF 介绍.有办法做到这一点.但是我找不到正确的类和引用来添加到我的 C# 项目中.是否有任何教程如何在 C# 中实现这一点?我搜索了很多，但没有找到对我有帮助的东西.

My problem is, I have no idea how to do this in C#. I can't find the right introduction to WCF. There are ways to do this. But I can't find the right classes and references to add to my C# project. Are the any tutorials how to achieve this in C#? I searched a lot and found nothing which helped me.

我想在运行时从我的 SOAP 服务器加载 WSDL，发出 SOAP 请求，检索答案并完成.但是我可以从哪里开始呢?关于 WCF 的 MSDN 站点只会让我更加困惑.

I want to load the WSDL from my SOAP Server at run time, make the SOAP request, retrieve the answer and be done. But where can I get started? The MSDN site about WCF is only confusing me more.

编辑:可能没有必要在运行时获取 WSDL 文件.所以不再需要了.
我使用 svcutil 创建该类并将其嵌入到我的项目中.我还没有能够测试它，因为我在使用 MySQL 数据库时遇到了一些问题(它正在运行并且可以从 mysql 命令行工具或 mysqladmin 访问，但我无法使用任何其他程序连接到它......).一旦我知道它是否有效，我会立即报告.

Edit: It probably is not necessary to fetch the WSDL file at run time. So that is not needed anymore.
I used svcutil to create the class and embedded it in my project. I haven't been able to test it yet, because I have some trouble with the MySQL database (It's running and accessible from the mysql command line tool or mysqladmin, but I can't connect to it with any other programm...). I'll report back as soon as I know if it works.

编辑 2:我遵循了 Kevs 方法，最终效果很好.我的最后一个问题是，我在 DLL 中使用了服务类.我也需要使用 DLL 的程序中的 app.config.在我这样做之后，效果很好.

Edit 2: I've followed Kevs approach and it worked out very good in the end. My final problem was, that I used the Service Class in a DLL. I needed the app.config in the programm which used the DLL too. After I did that it worked out well.

推荐答案

执行此操作的最快方法是右键单击客户项目中的引用"下的添加服务引用".将对话框指向 WSDL 的位置，然后单击 Go:

The quickest way to do this is to do right-click "Add Service Reference" in your client's project under References. Point the dialogue at the location of the WSDL and click Go:

我使用的 URL 用于 .NET 服务引用的样式，您需要替换为您的 PHP SOAP 服务用于公开其 WSDL 的任何内容.

The URL I used was for the style of a .NET service reference, you'll need to replace with whatever your PHP SOAP service uses to expose its WSDL.

这样做将生成一个客户端代理，您可以将其实例化以与您的网络服务进行通信.

Doing this will generate a client side proxy you can instantiate to communicate with your web service.

要访问该服务，您可以执行以下操作(尽管您的具体实现会有所不同):

To access the service you can then do something like (although your specific implementation won't be the same):

MyService.MyWebServiceSoapClient ws = new MyService.MyWebServiceSoapClient();
string result ws.DoThing();

要特别注意代理类名的SoapClient部分，这是由代理代码生成器添加到soap服务名中的.

Pay particular attention to the SoapClient part of the proxy class name, this is added to the name of the soap service name by the proxy code generator.

代理生成器还将在您的 web.config 或 app.config 文件中创建所有必要的配置.

The proxy generator will also create all the necessary configuration in your web.config or app.config file.
