因为我自己原来没有动态调用过wsdl，所有调用期间找了很多例子，浪费了很多时间，现在项目结束把这个动态调用方法放上来，以供参考

 

string eg= "https://xxxxxxxxx/scan?wsdl";//需要调用方法的地址

string url= "https://xxxxxxxxx/scan“;

 String str=  "hksfafasf";//方法所需参数

WebServiceAgent ag = new WebServiceAgent(url);

//调用方法获取输出结果 

string resultStr = (string)ag.Invoke("scanPay", str); //scanPay方法名称

public class WebServiceAgent

    {

        private object agent;

        private Type agentType;

        private const string CODE_NAMESPACE = "Beyondbit.WebServiceAgent.Dynamic";

        public WebServiceAgent(string url)

        {

            XmlTextReader reader = new XmlTextReader(url + "?wsdl");

            //创建和格式化 WSDL 文档    

            ServiceDescription sd = ServiceDescription.Read(reader);

            //创建客户端代理代理类    

            ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();

            sdi.AddServiceDescription(sd, null, null);

            //使用 CodeDom 编译客户端代理类    

            CodeNamespace cn = new CodeNamespace(CODE_NAMESPACE);

            CodeCompileUnit ccu = new CodeCompileUnit();

            ccu.Namespaces.Add(cn);

            sdi.Import(cn, ccu);

            CSharpCodeProvider icc = new CSharpCodeProvider();

            CompilerParameters cp = new CompilerParameters(new string[] { "System.Data.dll" }); // 在此添加所缺的dll，比如"System.Data.dll"  

            CompilerResults cr = icc.CompileAssemblyFromDom(cp, ccu);

            agentType = cr.CompiledAssembly.GetTypes()[0];

            agent = Activator.CreateInstance(agentType);

        }

        public object Invoke(string methodName, params object[] args)

        {

            MethodInfo mi = agentType.GetMethod(methodName);

            return this.Invoke(mi, args);

        }

        public object Invoke(MethodInfo method, params object[] args)

        {

            return method.Invoke(agent, args);

        }

        public MethodInfo[] Methods

        {

            get

            {

                return agentType.GetMethods();

            }

        }

    }  

 

总结：接口调通之后感觉也是很简单，但是之前是真的不知道发生了什么，记录一下
