使用ConfigurationManager加载System.ServiceModel配置节

using System.Configuration;
using System.ServiceModel;
using System.ServiceModel.Configuration;

// 加载System.ServiceModel配置节
ServiceModelSectionGroup serviceModelSectionGroup = ServiceModelSectionGroup.GetSectionGroup(ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None));

// 获取服务终结点配置
ServiceEndpointCollection serviceEndpoints = serviceModelSectionGroup.Services.Services["MyService"].Endpoints;

// 创建服务主机
ServiceHost serviceHost = new ServiceHost();

// 添加服务终结点
foreach (ServiceEndpointElement serviceEndpointElement in serviceEndpoints)
{
    serviceHost.AddServiceEndpoint(Type.GetType(serviceEndpointElement.Contract), new BasicHttpBinding(serviceEndpointElement.BindingConfiguration), serviceEndpointElement.Address);
}

// 打开服务主机
serviceHost.Open();
