Constant value cannot be converted to a 'bool' using a switch statement C#

Question

When I try to evaluate the SelectedIndex of a CheckBoxList and at bool. I receive a error on the case in my switch statement in C#. The error is Constant value '0' cannot be converted to a 'bool'. Is there a way that I can evaluate both with in a switch statement? I know I can use a if statement, but I would rather use a switch statement if I could.

Here is my code:

switch ((CBL_PO.SelectedIndex == 0) && (boolIsNotValid == true))
            {
                case 0: case true:
                    //Do Something
                    break;
            }

Answer 1

Since the only values in the switch can be true or false, drop the case 0.

Alternatively, you could better use an if:

if (CBL_PO.SelectedIndex == 0 && boolIsNotValid)
{ }
else
{ }

Since I think you might be trying to do a check on both values in the switch: not possible. This is your best option:

switch (CBL_PO.SelectedIndex)
{
    case 0:
    {
        if (boolIsNotValid)
        { }
        else
        { }

        break;
    }
}
