XML,Dictionary的应用有关于页面之间接收和传递参数的又一解决方案 [原创]

*此次的程序主要解决了页面之间接收和传递多个参数的问题。

思路：以XML配置化的思想编写此DEMO的。
            主要对项目中参数接收和传递做到可配置化，宜维护。。.

文字流程图：1.A页面Response.Write一个Form到B页面;
                        2.B页面接收之后，B页面中有"下一步按钮"，Press Button之后，提交从A Page接收到C Page.
                   
A Page:-----Default.aspx
B.Page------WebForm1.aspx
C.Page------WebForm2.aspx
CommonClass -----ParamClass
PageBaseClass-----BaseIPage
XML-----ParamDictionary.xml

以下是代码，供参考
