webservice问题
为什么我的webservice不能这样访问:http://127.0.0.1:42348/WebService/AccountService.asmx/SayHelloTo?Name=aaa
error:Request format is unrecognized for URL unexpectedly ending in '/SayHelloTo'.
这样访问又可以:http://127.0.0.1:42348/WebService/AccountService.asmx --------------------编程问答-------------------- 要求格式是无法辨识的网址意外结束的' / SayHelloTo ' --------------------编程问答-------------------- 你要干吗?
访问webservice 的参数不是这么穿的... --------------------编程问答--------------------

着是个动态的你可以参照下!
