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<T>(string url)
{
return CreateWCFServiceByURL<T>(url, "wsHttpBinding");
}
public static T CreateWCFServiceByURL<T>(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<T> factory = new ChannelFactory<T>(binding, address);
return factory.CreateChannel();
}
#endregion
#region 创建传输协议
/// <summary>
/// 创建传输协议
/// </summary>
/// <param name="binding">传输协议名称</param>
/// <returns></returns>
private static Binding CreateBinding(string binding)
{
Binding bindinginstance = null;
if (binding.ToLower() == "basichttpbinding")
{
BasicHttpBinding ws = new BasicHttpBinding();
ws.MaxReceivedMessageSize = 65535000;
bindinginstance = ws;
}
else if (binding.ToLower() == "netnamedpipebinding")
{
NetNamedPipeBinding ws = new NetNamedPipeBinding();
ws.MaxReceivedMessageSize = 65535000;
bindinginstance = ws;
}
else if (binding.ToLower() == "netpeertcpbinding")
{
NetPeerTcpBinding ws = new NetPeerTcpBinding();
ws.MaxReceivedMessageSize = 65535000;
bindinginstance = ws;
}
else if (binding.ToLower() == "nettcpbinding")
{
NetTcpBinding ws = new NetTcpBinding();
ws.MaxReceivedMessageSize = 65535000;
ws.Security.Mode = SecurityMode.None;
bindinginstance = ws;
}
else if (binding.ToLower() == "wsdualhttpbinding")
{
WSDualHttpBinding ws = new WSDualHttpBinding();
ws.MaxReceivedMessageSize = 65535000;
bindinginstance = ws;
}
else if (binding.ToLower() == "webhttpbinding")
{
WebHttpBinding ws = new WebHttpBinding();
ws.MaxReceivedMessageSize = 65535000;
bindinginstance = ws;
}
else if (binding.ToLower() == "wsfederationhttpbinding")
{
WSFederationHttpBinding ws = new WSFederationHttpBinding();
ws.MaxReceivedMessageSize = 65535000;
bindinginstance = ws;
}
else if (binding.ToLower() == "wshttpbinding")
{
WSHttpBinding ws = new WSHttpBinding(SecurityMode.None);
ws.MaxReceivedMessageSize = 65535000;
ws.Security.Message.ClientCredentialType = System.ServiceModel.MessageCredentialType.Windows;
ws.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Windows;
bindinginstance = ws;
}
return bindinginstance;
}
#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<Interface>(url);
