最近项目需要调用对方java写的webservice接口
调用示例：
//接收结果
XmlNode xmlNode1;
string strSenddata = "";//这个是要发送的报文数据
Hashtable ht = new Hashtable();
ht.Add("xmlIn", strSenddata);
xmlNode1 = PrintFaPiao.WebServiceCaller.QuerySoapWebService("http://testservicebus.sinosig.com/servicemgr/services/outputOtherSubject", "outputOtherSubject", ht);//接口地址，方法名，发送报文
WebServiceCaller类：
1 using System;
2 using System.Collections;
3 using System.IO;
4 using System.Net;
5 using System.Text;
6 using System.Xml;
7 using System.Xml.Serialization;
8 namespace PrintFaPiao

16 //webServices 应该支持Get和Post调用，在web.config应该增加以下代码

如果遇到xml转换错误，可能是编码问题，更改下请求的编码格式或者更改下接收的编码格式（上面例子中开始用utf-8接收结果转换xml的时候提示缺少根元素，于是改成默认编码后编译成功）
