怎么调用webservice
敢问各位大侠一个问题，我有一个webservice的地址，例如：http://192.168.0.138/Tweb/Tsoap没有暴露WSDL，没有暴露调用哪个asmx文件，请问我该如何调用里面的protest（）方法？小弟是初学者，请各位指教了 --------------------编程问答-------------------- webservice系列教学（14)-如何调用webservice(vc5)-.NET教程,Web Service开发

写入你的服务网址
就会得到服务的客户类
理论上wsdl就是http://192.168.0.138/Tweb/Tsoap?wsdl --------------------编程问答-------------------- 加个?wsdl --------------------编程问答-------------------- 我也看不懂啊 --------------------编程问答-------------------- 在项目里面 鼠标右键 添加web引用 简单吧 。。。
