Convert vb.net asp.net code to C#

Checked='<%# iif(eval("isActive")="True","Fal开发者_StackOverflow中文版se","True")  %>'

What is the equivalent in c# for asp.net? I have tried my best to convert it but i could not.

Checked='<%# !(bool)Eval("isActive") %>'

Checked='<%# (bool)Eval("isActive") ? false : true %>'
