.NET - 在没有 app.config 的情况下部署 WCF 客户端 [英] .NET - deploying a WCF client, without an app.config
问题描述
我正在为 WCF 服务编写客户端.这是一个包含用 C#、C++、VB 和 Java 编写的模块的更大系统中的单个应用程序.所有应用都共享通用配置和日志记录机制，无论它们是用什么语言编写的.
I'm writing a client to a WCF service. This is a single app in a larger system that includes modules written in C#, C++, VB, and Java. All of the apps share common configuration and logging mechanisms, regardless of what language they were written in.
我想弄清楚如何构建客户端应用程序，以便它可以在没有 app.config 的情况下运行.为什么?因为 app.config 中的大部分内容都是不允许系统管理员更改的样板文件，并且应该允许系统管理员更改的设置应该在系统范围的配置中，而不是在 app.config 文件中坐在bin目录下.
I'd like to figure out how to build the client application so that it will run without an app.config. Why? Because most of what is in the app.config is boilerplate that the sysadmins shouldn't be allowed to change, and what settings the sysadmins should be allowed to change should be in the system-wide configuration, and not in an app.config file sitting in the bin directory.
示例 - 客户端的 app.config 当前如下所示:
Case in point - the client's app.config currently looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<customBinding>
<binding name="WSHttpBinding_ICourierService">
<security defaultAlgorithmSuite="Default" authenticationMode="SecureConversation"
...
</security>
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Default" writeEncoding="utf-8">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"
maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
</textMessageEncoding>
<httpTransport manualAddressing="false"
...
useDefaultWebProxy="true" />
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://localhost:57102/MyService.svc"
...
>
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</client>
</system.serviceModel>
</configuration>
系统管理员不应该处理一堆不透明的样板文件.其中大部分是由 Visual Studio 插入的.我对文件进行了一项更改 - 我增加了 <endpoint address=""/>.
It's a bunch of opaque boilerplate that the sysadmins shouldn't have to deal with. Most of it was inserted by Visual Studio. I've made one change in the file - I increased the max size in <readerQuotas/>. But that's a change that I don't want the sysadmins to mess with. And there's nothing else in the file I want the sysadmins to mess with except for <endpoint address=""/>.
我从系统范围的配置中提取端点地址，并在代码中设置它.此文件中没有用户可编辑的内容.
And I'm pulling the endpoint address from the system-wide configuration, and setting it in code. There's nothing in this file that should be user-editable.
那么，我如何配置东西，以便我不需要让它出现?
So, how do I configure things so that I don't need to have it present?
我是否可以将它作为资源嵌入到程序集中，并挂接到 app.config 加载过程中，就像我处理所需的 DLL 一样?
Can I embed it as a resource in the assembly, and hook into the app.config load process, the way I do with required DLLs?
我使用代码设置端点地址的方式是创建代码来配置事物的唯一选择吗?在代码中创建必要的绑定等?那么，鉴于这些不透明的 XML 块，我如何知道要编写什么代码?
Is the only choice to create code to configure things, the way I'm using code to set the endpoint address? Create the necessary bindings, etc., in code? How, then, do I know what code to write, given these chunks of opaque XML?
推荐答案
您可以使用以下代码来创建配置所执行的绑定.我不确定这是否会让您完全删除该文件，但如果是这种情况，应用程序将不会使用该配置.将您自己的值放在超时等中.
You can use the following code to creating the bindings which is what the config is doing. I am not sure whether that will let you remove the file altogether but the application won't use the config if this is the case. Put your own values in the timeouts, etc.
var binding = new WSHttpBinding();
binding.SendTimeout = new TimeSpan(0, 0, 0, 0, 100000);
binding.OpenTimeout = new TimeSpan(0, 0, 0, 0, 100000);
binding.MaxReceivedMessageSize = 10000;
binding.ReaderQuotas.MaxStringContentLength = 10000;
binding.ReaderQuotas.MaxDepth = 10000;
binding.ReaderQuotas.MaxArrayLength = 10000;
var endpoint = new EndpointAddress("http://localhost:57102/MyService.svc");
var myClient = new WebServiceclient(binding, endpoint);
