现在需要向另一个网页A中传递一个参数,参数中包含一个页面B地址,A做完相关动作后转向B,B链接类似如下:http://192.168.0.8/CWBASE/MC/MCMainFace/MCMainFace.asp?MCID=003&DWINFO=1001001|集团股份有限公司(本部)
请问如何把“http://192.168.0.8/CWBASE/MC/MCMainFace/MCMainFace.asp?MCID=003&DWINFO=1001001|集团股份有限公司(本部)”在c#中做base64编码,试了几种方法,都不能解码,全英文路径没问题。

这我已经试过,不行的。
对方是asp页面,且里面只能使用vbscript脚本解码:
