[转]使用代码去描述WCF配置文件

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 = ;

        Bindins.MaxReceivedMessageSize = ;

        Bindins.MessageEncoding = WSMessageEncoding.Text;

        Bindins.TextEncoding = Encoding.UTF8;

        Bindins.UseDefaultWebProxy = true;

        Bindins.ReaderQuotas.MaxDepth = ;

        Bindins.ReaderQuotas.MaxStringContentLength = ;

        Bindins.ReaderQuotas.MaxArrayLength = ;

        Bindins.ReaderQuotas.MaxBytesPerRead = ;

        Bindins.ReaderQuotas.MaxNameTableCharCount = ;

        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。
