最后报错object类型错误 --------------------编程问答-------------------- 最后一段代码79行，
private void ParseQueryString( string queryString, ref string asmbName, ref string typeName, ref string funcName, ref object[] objectParam )
看看 --------------------编程问答-------------------- 你这个反射 。。。。。。。。。。。 --------------------编程问答-------------------- 提交传递参数可以用ajax json来做，个人比较喜欢那种方法。
这样的调用为什么不做成 webService 呢
补充：.NET技术 , C#
