转自：使用代码去描述WCF配置文件

在应用程序部署的时候，WCF客户端因为服务器地址的变化，需要修改程序配置文件的地址URL，手动修改很不方便，还会造成错误，所以尽量把描述WCF配置文件的配置使用代码方式进行描述，通过在软件中输入服务器IP地址的方式，动态修改访问的URL，这样比较方便，也不会出错，导致程序运行异常。

下面我将一个WCF部署文件采用代码方式描述： 

WCF客户端的配置文件：

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
    <system.serviceModel>  
        <bindings>  
            <wsHttpBinding>  
                <binding name="WSHttpBinding_IMainService" closeTimeout="00:01:00"  
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"  
                    bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"  
                    maxBufferPoolSize="524288" maxReceivedMessageSize="65536"  
                    messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"  
                    allowCookies="false">  
                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"  
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />  
                    <reliableSession ordered="true" inactivityTimeout="00:10:00"  
                        enabled="false" />  
                    <security mode="Message">  
                        <transport clientCredentialType="Windows" proxyCredentialType="None"  
                            realm="" />  
                        <message clientCredentialType="Windows" negotiateServiceCredential="true"  
                            algorithmSuite="Default" establishSecurityContext="true" />  
                    </security>  
                </binding>  
            </wsHttpBinding>  
        </bindings>  
        <client>  
            <endpoint address="http://localhost:8888/DataCenter.Factory/MainService/"  
                binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IMainService"  
                contract="IMainService" name="WSHttpBinding_IMainService">  
                <identity>  
                    <servicePrincipalName value="host/WIN-QFIKKT28EHC" />  
                </identity>  
            </endpoint>  
        </client>  
    </system.serviceModel>  
</configuration>

编程中使用代码描述上述文件：在这里客户端引用的WCF服务命名空间定义为DataCenterFatoryC，客户端访问对象为  DataCenterFatoryC.MainServiceClient MainServiceClient1;

   using System.ServiceModel;  
  
   WSHttpBinding Bindins;  
  
   DataCenterFatoryC.MainServiceClient MainServiceClient1;  
  
  
   private void MainForm_Load(object sender, EventArgs e)  
   {  
        Bindins = new WSHttpBinding();//设置绑定  
        Bindins.CloseTimeout = TimeSpan.Parse("00:01:00");  
        Bindins.OpenTimeout = TimeSpan.Parse("00:01:00");  
        Bindins.ReceiveTimeout = TimeSpan.Parse("00:10:00");  
        Bindins.SendTimeout = TimeSpan.Parse("00:01:00");  
        Bindins.BypassProxyOnLocal = false;  
        Bindins.TransactionFlow = false;  
        Bindins.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;  
        Bindins.MaxBufferPoolSize = 524288;  
        Bindins.MaxReceivedMessageSize = 65535;  
        Bindins.MessageEncoding = WSMessageEncoding.Text;  
        Bindins.TextEncoding = Encoding.UTF8;  
        Bindins.UseDefaultWebProxy = true;  
        Bindins.ReaderQuotas.MaxDepth = 32;  
        Bindins.ReaderQuotas.MaxStringContentLength = 8192;  
        Bindins.ReaderQuotas.MaxArrayLength = 16383;  
        Bindins.ReaderQuotas.MaxBytesPerRead = 4096;  
        Bindins.ReaderQuotas.MaxNameTableCharCount = 16384;  
        Bindins.ReliableSession.Ordered = true;  
        Bindins.ReliableSession.InactivityTimeout = TimeSpan.Parse("00:10:00");  
        Bindins.ReliableSession.Enabled = false;  
        Bindins.Security.Mode = SecurityMode.Message;  
        Bindins.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;  
        Bindins.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;  
        Bindins.Security.Message.ClientCredentialType = MessageCredentialType.Windows;  
        Bindins.Security.Message.NegotiateServiceCredential = true;  
        Bindins.Security.Message.AlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Default;  
        Bindins.Security.Message.EstablishSecurityContext = true; 
  
  
        string address = "http://localhost:8888/DataCenter.Factory/MainService/";//服务终结点的URL  
        MainServiceClient1 = new DataCenterFatoryC.MainServiceClient(Bindins, new EndpointAddress(address));  
        MainServiceClient1.Open();  
    }

通过对Bindins的参数设置，能有效的描述访问过程的一些问题，比如上传下载大文件，大数据表都依赖重要参数的设置，否则运行中会有异常错误发生，这是我们应该注意的。
