杏和接口service调试出现问号????????+????乱码如何解决 <TEST_ORDER_NAME>????????+????</TEST_ORDER_NAME>
请问 c# 有什么好解决方案？

Answer 1

 WebReference.service bll = new WebReference.service();
  string dataGBK = Encoding.GetEncoding("gb2312").GetString(Encoding.UTF8.GetBytes(bll.XHLisWebserviceFun(Data))); WebReference.service bll = new WebReference.service();
  string dataGBK = Encoding.GetEncoding("gbk").GetString(Encoding.UTF8.GetBytes(bll.XHLisWebserviceFun(Data)));
 WebReference.service bll = new WebReference.service();
  string dataGBK = Encoding.GetEncoding("utf-8").GetString(Encoding.UTF8.GetBytes(bll.XHLisWebserviceFun(Data)));均显示乱码

Answer 2

c#调用delphi开发的webservice接口,中文返回值为乱码(一个汉字返回???)

Answer 3

有的说是delphi 在编写 web server的时候 编码问题；
主要设置控件 HttpSoapDispatcher 中的 option 将 soUTF8InHeader = True
和 soDontSendEmptyNode = True 设置一下就可以了

Answer 4

string dataGBK = Encoding.GetEncoding("gb2312").GetString(Encoding.UTF8.GetBytes(bll.XHLisWebserviceFun(Data)));
并不能实现你将 utf-8 编码的数据转换成 gb2312 编码的数据的目的
否则 Encoding.Convert 就形同虚设了为了便于探察你所遇到的问题，你最好贴出 bll.XHLisWebserviceFun(Data) 的 base64 编码后的内容
