主题：网址中的中文如何转换?

Dim url As String = e.Request.URL.ToString '通用e参数获取的url如下:

http://xxx.xxx.xxx/mobile/html/cgdd_edit.html?_identify=4629&type=edit&tbname=采购单&flowID=0

foxtable界面中如何将上述网址中的中文转投为utf-8的格式即:

http://xxx.xxx.xxx/mobile/html/cgdd_edit.html?_identify=4629&type=edit&tbname=%E9%87%87%E8%B4%AD%E5%8D%95&flowID=0

谢谢!
