从 app.config 到代码的 BasicHTTPBinding答案

【问题标题】：BasicHTTPBinding from app.config to code从 app.config 到代码的 BasicHTTPBinding

【问题描述】：

我坚持实现以前在 app.config 中定义的 BasicHTTPBinding（在类库中不存在）。我希望这些设置是预定义的，因此可以在我的 .dll 中进行硬编码。

这是我的 app.config 所说的：

<!-- language: xaml -->
<bindings>
  <basicHttpBinding>
    <binding name="ImageServerServiceSoapBinding" messageEncoding="Mtom" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
        <message clientCredentialType="UserName" algorithmSuite="Default"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://xx.xx.xx.xx:xx/xyz" binding="basicHttpBinding" bindingConfiguration="ImageServerServiceSoapBinding" contract="xyz.ImageServer" name="ImageServerPort"/>
</client>

我开始以编程方式设置绑定，但由于我的 _binding 中没有在 app.config 中设置的方法而卡住了？！

<!-- language: c# -->
System.ServiceModel.Channels.Binding _binding = new System.ServiceModel.BasicHttpBinding();
System.ServiceModel.EndpointAddress _address = new System.ServiceModel.EndpointAddress(@"http://xx.xx.xx.xx:xxx/xyz");

_binding.Name = "ImageServerServiceSoapBinding";
_binding.CloseTimeout = new TimeSpan(0, 1, 0);
_binding.OpenTimeout = new TimeSpan(0, 1, 0);
_binding.ReceiveTimeout = new TimeSpan(0, 10, 0);
_binding.SendTimeout = new TimeSpan(0, 1, 0);

this._Client = new ImageServerClient(_binding, _address);

_Settings.TraverseData.TraverseWidth = double.Parse(_Client.getCameraInfo(d2els_selectedcam).traverseLength);

由于从绑定到客户端 (text/xml; charset=utf-8) 的内容类型 (multipart/related;) 不兼容，最后一行失败？！

如何访问 BasicHTTPBinding 中的这些设置？还是我有错误的概念？

_binding.maxDepth // ... etc.

不是 BasicHTTPBinding 的成员。

对于所有面临同样问题的人来说：

谷歌花了很长时间才在框架中找到在 app.config 中简单命名的基类。上面的 app.config 代码如下所示：

        System.ServiceModel.BasicHttpBinding _binding = new System.ServiceModel.BasicHttpBinding();
        System.ServiceModel.EndpointAddress _address = new System.ServiceModel.EndpointAddress(@"http://xx.xx.xx.xx:xxx/xyz");

        _binding.Name = "ImageServerServiceSoapBinding";
        _binding.CloseTimeout = new TimeSpan(0, 1, 0);
        _binding.OpenTimeout = new TimeSpan(0, 1, 0);
        _binding.ReceiveTimeout = new TimeSpan(0, 10, 0);
        _binding.SendTimeout = new TimeSpan(0, 1, 0);

        _binding.MessageEncoding = System.ServiceModel.WSMessageEncoding.Mtom;
        _binding.AllowCookies = false;
        _binding.BypassProxyOnLocal = false;
        _binding.HostNameComparisonMode = System.ServiceModel.HostNameComparisonMode.StrongWildcard;
        _binding.MaxBufferSize = Int32.MaxValue;
        _binding.MaxBufferPoolSize = Int16.MaxValue;
        _binding.MaxReceivedMessageSize = Int32.MaxValue;
        _binding.TextEncoding = System.Text.Encoding.UTF8;
        _binding.TransferMode = System.ServiceModel.TransferMode.Buffered;
        _binding.UseDefaultWebProxy = true;

        System.Xml.XmlDictionaryReaderQuotas _readerquotas = new System.Xml.XmlDictionaryReaderQuotas();

        _readerquotas.MaxDepth = Int32.MaxValue;
        _readerquotas.MaxStringContentLength = Int32.MaxValue;
        _readerquotas.MaxArrayLength = Int32.MaxValue;
        _readerquotas.MaxBytesPerRead = Int32.MaxValue;
        _readerquotas.MaxNameTableCharCount = Int32.MaxValue;

        _binding.ReaderQuotas = _readerquotas;

        _binding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.None;
        _binding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.None;
        _binding.Security.Transport.ProxyCredentialType = System.ServiceModel.HttpProxyCredentialType.None;
        _binding.Security.Transport.Realm = "";

        _binding.Security.Message.ClientCredentialType = System.ServiceModel.BasicHttpMessageCredentialType.UserName;
        _binding.Security.Message.AlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Default;

        this._Client = new ImageServerClient(_binding, _address);

我的问题是我认为 ImageServerClient 函数需要一个

System.ServiceModel.Channels.Binding

但也接受了一个

System.ServiceModel.BasicHttpBinding.

后者包含所有预期的方法；现在无需 app.config 文件即可连接到服务器 :)
