POST方法调用webservice
比如说url=“http://localhost/Service/Service.asmx”;webservice中的一个方法是      public   XmlDataDocument   GetInfor(int   nLangID,   int   nStartCount,   int   nCount);我怎么用post方法传参数啊,还有怎么把返回的xml页面保存为xml文档,新手啊,请大家帮忙啊!
------解决方案--------------------接分,专业地
------解决方案--------------------System.Data.DataSet ds = new System.Data.DataSet(); 
 ds.ReadXml( "http://localhost/Service/Service.asmx?langid=/*.....省略*/ "); 
 System.Xml.XmlDataDocument doc = new System.Xml.XmlDataDocument(ds);   
 试试.这块不熟,仅供参考

------解决方案--------------------可以用web应用来做  locolhost tt = new locolhost ();   
              XmlNode xml = tt.GetCategories(1, 1, 1); 
             string strXML = xml.OuterXml.ToString(); 
             strXML =  " <?xml version=\ "1.0\ " encoding=\ "utf-8\ " ?>  " + strXML;   
             XmlDocument xmlDoc = new XmlDocument(); 
             xmlDoc.LoadXml(strXML); 
             xmlDoc.Save( "c:\\tt.xml ");
