C# 动态调用WebService

动态调用webservice,就可以不用添加web引用了,上线的话也只是需要改一下wsdl地址就可以了1.动态调用的方法:

1. ///<summary>
2. ///动态webservice调用
3. ///</summary>
4. ///<returns>string</returns>
5. publicstringwsTest()
6. {
7. stringurl="http://localhost:8080/myWebserviceTest/services/myServices?wsdl";//wsdl地址
8. stringname="wsTest";//javaWebService开放的接口
9. WebServicePRoxywsd=newWebServiceProxy(url,name);
11. string[]str={"测试c#调用java的webService","HelloWebService"};
13. stringsuc=(string)wsd.ExecuteQuery(name,str);
15. returnsuc;
16. }

2.动态调用具体类:

1. usingSystem;
2. usingSystem.Collections;
3. usingSystem.ComponentModel;
4. usingSystem.Data;
5. usingSystem.Linq;
6. usingSystem.Web;
7. usingSystem.Web.Services;
8. usingSystem.Web.Services.Protocols;
9. usingSystem.xml.Linq;
12. usingSystem.IO;
13. usingSystem.Net;
14. usingSystem.CodeDom;
15. usingSystem.CodeDom.Compiler;
16. usingSystem.Web.Services.Description;
17. usingSystem.Xml.Serialization;
18. usingSystem.Web.Services.Discovery;
19. usingSystem.Xml.Schema;
20. usingSystem.Text;
21. usingSystem.Security.Cryptography;
22. usingSystem.Reflection;
23. usingSystem.Collections.Generic;
24. usingSystem.Xml;
26. namespaceTPSVService
27. {
28. ///<summary>
