動态調用webservice,就可以不用添加web引用了,上線的話也隻是需要改一下wsdl位址就可以了
1.動态調用的方法:
/// <summary>
/// 動态webservice調用
/// </summary>
/// <returns>string</returns>
public string wsTest()
{
string url = "http://localhost:8080/myWebserviceTest/services/myServices?wsdl";//wsdl位址
string name = "wsTest";//javaWebService開放的接口
WebServiceProxy wsd = new WebServiceProxy(url, name);
string[] str = { "測試c#調用java的webService" , "Hello WebService"};
string suc = (string)wsd.ExecuteQuery(name, str);
return suc;
}
2.動态調用具體類:

java接口可以用Object[]類型接收參數
建立個c#的webservice應用,可以運作本示例
