动态调用WCF服务

动态调用WCF服务

动态调用WCF服务，只需要提供*.svc地址，

1:命名空间：

using System.ServiceModel.Channels;
using System.ServiceModel;

2:创建访问类InvokeContext

public class InvokeContext
{

#region Wcf服务工厂
public static T CreateWCFServiceByURL(string url)
{
return CreateWCFServiceByURL(url, “wsHttpBinding”);
}
public static T CreateWCFServiceByURL(string url,string bing)
{
if (string.IsNullOrEmpty(url)) throw new NotSupportedException(“this url isn`t Null or Empty!”);
EndpointAddress address = new EndpointAddress(url);
Binding binding = CreateBinding(bing);
ChannelFactory factory = new ChannelFactory(binding, address);
return factory.CreateChannel();
}
#endregion

3.T为调用的接口类型，就是WCF返回的类的实例，由于我的WCF是基于接口的，所以加了一个接品类型判断，调用时直接写：Interface iface =
InvokeContext.CreateWCFServiceByURL(url);
