Get checked values from array

Question

I'm using mvc and I'm trying to loop through a array of checkboxes, but how do I exclude the ones that are "false" in that list?

for(int i = 0; i < TimeRange1.Length; i++)
        {
          if(TimeRange1[i] == "false" ....??)
        // dostuff
        }

or is there some better way of doing it?

if TimeRange1 is a checkbox array (see Tim S. Van Haren) then you should use better names like cbTimeRanges — RvdK

Please show the relevant portion of your view. Specifically, the Html.CheckBox() helper is meant to render only single checkboxes and must not be used to render a collection of checkboxes with the same name. — Levi

Since you are doing it with MVC - you could make TimeRange1 a bool[].

Then, you could always do this with linq

var newItems = TimeRange1.Select(i => i == false);

foreach(var item in newItems)
{
 ....
}

or you could simplify it

foreach(var item in TimeRange1.Select(i => i == false))
{
 ....
}

how do I get: foreach(var item in TimeRange1.Select(i => i != "false")) to work? I cant seem to get hold of the value

You can't not a string value. Remove the quotes.

...& change the type of TimeRange1.

Assuming TimeRange1 is your CheckBox[], try this:

for (int i = 0; i < TimeRange1.Length; i++)
{
    if (TimeRange1[i] == "on")
    {
       // dostuff
    }
}
