我想用Request.Form.获取其选中的值,可是不知道怎么获取不到，获取是空值。 
可是要如果把type="checkbox" 换成 type="radio"的时候用Request.Form就可以正常获取了，不知道怎么决绝，谢谢！！1

Answer 1

Request.Form[ChbIllness1.ClientID]
Request.Form[ChbIllness2.ClientID]
Request.Form[ChbIllness3.ClientID]

Answer 2

string str = Request.Params["Illness"];获取页面上所有的checkbox选中的项的id，已“，“分隔

Answer 3

.NET 不是很熟，不知道怎么变通，请你指教下，谢谢！

Answer 4

1，你的代码里checkbox的name不是一样的，
2，你的代码运行后name都变了，你查看源代码能看到，已经不是Illness了，所以肯定得不到。
原因估计是代码你复制进来的，可能造成格式不正规，建议把现有的input删掉，自己写

Answer 5

你的CheckBox是runat=server的吧？在页面中如果使用了母板页或者是自定义控件将更改id的，因此需要使用ClientID还有，如果是runat=server，你在后台可以直接去取这个控件的值（除非你重写了submit）。
