WCF客户端动态设置WCF服务器主机的地址的方法参考，可以连接多个相同WCF主机的方法...

最近做一个项目，需要在客户端灵活配置连接到哪个服务器的功能，例如客户端是一个，现在想连接A服务器就连A服务器，想连接B服务器就连接B服务器，当然不需要手动修改配置文件，直接通过程序来实现WCF目标主机的配置功能。

参考核心代码如下：

using System.ServiceModel;

namespace DotNet.WCFClient
{
using DotNet.IService;
using DotNet.Utilities;

publicclass ServiceFactory : IServiceFactory
{
privatestring host =string.Empty;
///<summary>
/// 主机地址
/// Host = "192.168.0.122";
///</summary>
publicstring Host
{
get
{
return host;
}
set
{
host = value;
}
}

privateint port =0;
///<summary>
/// 端口号

publicint Port
{
get
{
return port;
}
set
{
port = value;
}
}

public ServiceFactory()
{
}

///<summary>

publicvoid InitService()
{
}

///<summary>
/// 动态设定WCF主机地址端口的方法
///</summary>
///<param name="address">主机地址</param>
///<returns>主机地址</returns>
publicvirtual EndpointAddress GetHotsUrl(EndpointAddress address)
{
// 若当前配置都是空的，就不用生成新的URL了。
if (string.IsNullOrEmpty(Host) && (Port ==0))
{
return address;
}
// 判断当前配置的情况
string endpointAddress =string.Empty;
if (string.IsNullOrEmpty(Host))
{
Host = address.Uri.Host;
}
if (Port ==0)
{
Port = address.Uri.Port;
}
endpointAddress = address.Uri.Scheme +"://"+ Host +":"+ Port.ToString() + address.Uri.LocalPath;
address =new EndpointAddress(endpointAddress);
return address;
}

publicvirtual ISequenceService CreateSequenceService()
{
ChannelFactory<ISequenceService> channelFactory =new ChannelFactory<ISequenceService>("DotNet.Service.SequenceService");
channelFactory.Endpoint.Address = GetHotsUrl(channelFactory.Endpoint.Address);
// 加强安全验证防止未授权匿名调用
channelFactory.Credentials.UserName.UserName = BaseSystemInfo.ServiceUserName;
channelFactory.Credentials.UserName.Password = BaseSystemInfo.ServicePassword;
ISequenceService proxy = channelFactory.CreateChannel();
return proxy;
}

}
}
}

配套的配置文件参考如下：
