首先，我不是网络开发人员，所以请放轻松..

我继承了一个使用 Web 服务客户端的项目。我希望能够在多个环境中部署相同的 .config 文件，而无需直接对其进行编辑。为此，我不确定如何处理的唯一属性是<system.serviceModel> 部分中的地址：

<system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="CA_ServiceSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="1000000" maxBufferPoolSize="524288" maxReceivedMessageSize="1000000" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="16384" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
      <security mode="Transport">
        <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
        <message clientCredentialType="UserName" algorithmSuite="Default"/>
      </security>
    </binding>
    <binding name="CA_ServiceSoap1" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
        <message clientCredentialType="UserName" algorithmSuite="Default"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="https://myserver.contoso.com/CA_Service.asmx" binding="basicHttpBinding" bindingConfiguration="CA_ServiceSoap" contract="WebServices.CA_ServiceSoap" name="CA_ServiceSoap"/>
</client>

有没有办法可以在 .config 的 <endpoint> 标记中为“地址”属性输入一个虚拟值，然后在运行时通过代码正确定义它？

【解决方案1】：

创建客户端时，可以在代码中用basicHttpBinding更改端点的地址。

根据您提供的配置，我猜您创建客户端的代码可能类似于以下内容：

//Specify the binding to be used for the client.
BasicHttpBinding binding = new BasicHttpBinding() { Namespace = "WebServices.CA_ServiceSoap" };

//Specify the address to be used for the client.
EndpointAddress address =
     new EndpointAddress("https://myserver.contoso.com/CA_Service.asmx");

// Create a client that is configured with this address and binding.
CA_ServiceSoap client = new CA_ServiceSoap(binding, address);

感谢@S.Dav 为我指明了正确的方向。我最终所做的是将我发布的 XML 中的所有内容（它本身只是一个序列化对象）直接包含在我的代码中。唯一可变的属性是 URL：

BasicHttpBinding binding = new BasicHttpBinding()
{
    Namespace = "WebServices.CA_ServiceSoap",
    CloseTimeout = new TimeSpan(0, 1, 0),
    OpenTimeout = new TimeSpan(0,1,0),
    ReceiveTimeout = new TimeSpan(0,10,0),
    SendTimeout = new TimeSpan(0,1,0),
    AllowCookies = false,
    BypassProxyOnLocal = false,
    HostNameComparisonMode = HostNameComparisonMode.StrongWildcard,
    MaxBufferSize = 1000000,
    MaxBufferPoolSize = 524288,
    MaxReceivedMessageSize = 1000000,
    MessageEncoding = WSMessageEncoding.Text,
    TextEncoding = Encoding.UTF8,
    TransferMode = TransferMode.Buffered,
    UseDefaultWebProxy = true,
    ReaderQuotas = new XmlDictionaryReaderQuotas()
    {
        MaxDepth = 32,
        MaxStringContentLength = 16384,
        MaxArrayLength = 16384,
        MaxBytesPerRead = 4096,
        MaxNameTableCharCount = 16384
    }
};
binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport = new HttpTransportSecurity()
{
    ClientCredentialType = HttpClientCredentialType.None,
    ProxyCredentialType = HttpProxyCredentialType.None,
    Realm = ""
};
binding.Security.Message = new BasicHttpMessageSecurity()
{
    ClientCredentialType = BasicHttpMessageCredentialType.UserName,
    AlgorithmSuite = SecurityAlgorithmSuite.Default
};
client = new CA_ServiceSoapClient(binding, new EndpointAddress(Config.WebServiceURL));

作为未来的工作，我计划查看是否可能需要调整这些绑定属性以进行故障排除/性能并将它们添加为 appsettings，然后我将在 BasicHttpBinding 实例化中引用。
