动态调用webservice,做个笔记：

         }

             if ((classname == null) || (classname == ""))
             {
                 classname = WSHelper.GetWsClassName(url);
             }
             try
             {                   //获取WSDL
                 WebClient wc = new WebClient();
                 Stream stream = wc.OpenRead(url + "?WSDL");
                 ServiceDescription sd = ServiceDescription.Read(stream);
                 ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();
                 sdi.AddServiceDescription(sd, "", "");
                 CodeNamespace cn = new CodeNamespace(@namespace);
                 //生成客户端代理类代码
                 CodeCompileUnit ccu = new CodeCompileUnit();
                 ccu.Namespaces.Add(cn);
                 sdi.Import(cn, ccu);
                 CSharpCodeProvider icc = new CSharpCodeProvider();
                 //设定编译参数
                 CompilerParameters cplist = new CompilerParameters();
                 cplist.GenerateExecutable = false;
                 cplist.GenerateInMemory = true;
                 cplist.ReferencedAssemblies.Add("System.dll");
                 cplist.ReferencedAssemblies.Add("System.XML.dll");
                 cplist.ReferencedAssemblies.Add("System.Web.Services.dll");
                 cplist.ReferencedAssemblies.Add("System.Data.dll");
                 //编译代理类
                 CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);
                 if (true == cr.Errors.HasErrors)
                 {
                     System.Text.StringBuilder sb = new System.Text.StringBuilder();
                     foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors)
                     {
                         sb.Append(ce.ToString());
                         sb.Append(System.Environment.NewLine);
                     }
                     throw new Exception(sb.ToString());
                 }
                 //生成代理实例，并调用方法
                 System.Reflection.Assembly assembly = cr.CompiledAssembly;
                 Type t = assembly.GetType(@namespace + "." + classname, true, true);
                 object obj = Activator.CreateInstance(t);
                 System.Reflection.MethodInfo mi = t.GetMethod(methodname);
                 return mi.Invoke(obj, args);
                 // PropertyInfo propertyInfo = type.GetProperty(propertyname);
                 //return propertyInfo.GetValue(obj, null);
             }
             catch (Exception ex)
             {
                 throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace));
             }
         }
         private static string GetWsClassName(string wsUrl)
         {
             string[] parts = wsUrl.Split('/');
             string[] pps = parts[parts.Length - ].Split('.');
             return pps[];
         }
     }

需要在web.config中添加webservice的地址。

<add key="ConnetionHisExist" value="http://10.10.99.8:8808/HisIsExist.asmx"/>
<!--<add key="ConnetionUrlMsg" value="http://10.10.99.8:8082/MessageApi.asmx"/>-->
<add key="ConnetionUrlMsg" value="http://112.74.203.57:8000/MessageApi.asmx"/>

动态调用方式:

1、取得webconfig中的webservice的值

string MsgWebServiceurl = ConfigurationManager.AppSettings["ConnetionUrlMsg"].ToString();//取得webconfig中webservice值

2、组建字符串数组，访问

 string strxml = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>" +
 "<data>" +
 "<OrderNo>" + dt.Rows[]["order_no"].ToString() + "</OrderNo>" +
 "<MerBillNo>" + dt.Rows[]["merchant_billno"].ToString() + "</MerBillNo>" +
 "<RefundMethod>" + "" + "</RefundMethod>" +
 "<Amount>" + dt.Rows[]["real_cost"].ToString() + "</Amount>" +
 "<OperUser>" + dt.Rows[]["oper_user"].ToString() + "</OperUser>" +
 "<TermNo>" + dt.Rows[]["termno"].ToString() + "</TermNo>" +
 "<HisRefundNo>" + dt.Rows[]["merchant_billno"].ToString() + "</HisRefundNo>" +
 "<HisNo>" + dt.Rows[]["merchant_billno"].ToString() + "</HisNo>" +
 "<ChannelTransNo>" + dt.Rows[]["tran_no"].ToString() + "</ChannelTransNo>" +
 "<PayAppSource>" + dt.Rows[]["payappcode"].ToString() + "</PayAppSource>" +
 "<PaySourceCode>" + dt.Rows[]["paysourcecode"].ToString() + "</PaySourceCode>" +
 "<Flushes>" + "" + "</Flushes>" +//0-退款 1-冲正
 "<SignType>" + "" + "</SignType>" +
 "<SignData>" + SignData + "</SignData>" +
 "</data>";
 
 string[] argsMsg = new string[];//组建字符串数组
 argsMsg[] = "F000105";//访问类型
 argsMsg[] = strxml;//入参
 argsMsg[] = "xml";//返回类型 xml ,json
 object Msgresult = WSHelper.InvokeWebService(MsgWebServiceurl, "MuPayInterface", argsMsg);

3、接下来对返回的object转化为字符串，然后解析这个字符串xml。

4、调用其他入参不是xml类型的

 string isExistWebServiceurl = ConfigurationManager.AppSettings["ConnetionHisExist"].ToString();//取得webconfig中webservice值
 
 string[] args = new string[];
 args[] = tran_no;
 

 object result = WSHelper.InvokeWebService(isExistWebServiceurl, "HisExistsOrNot", args);

返回的result是一个int类型，进行转换后，即可用了。
