correct syntax for switch statement

[adiel]

Hello, this must be an easy one. I want to perform code based on the
selected item from a radio button in asp.net. I have the following
code:

// Setup Living Area
switch (true)
{
case radRental.Checked:
livingArea = "Rental Properties Listing";
break;
case radHome.Checked:
livingArea = "Home Property Listing";
break;
case radApartment.Checked:
livingArea = "Apartment Property Listing";
break;
default:
livingArea = "";
break;
}

I am getting an error stating "a constant value is expected" on each
item in the case statement. I know I must be missing a cast or
something, can someone help?

Thanks,
Adiel

For the C# switch statement to work, all the possible values of your
cases MUST be known at compile time. Using a variable precludes this
necessity therefore your code doesn't compile. Also, you are trying to
circumvent the kind of scenario for which a switch case statement is
perfect by twisting it (the switch(true) statement, for instance).

In your scenario, an "if - else if - else" construct might be more
suitable.

On a side note, if you were to use the RadioButtonList control (quirks
notwithstanding), you would not have to do this kind of checking.

try this

<asp:RadioButtonList ID="rd1" runat="server" OnSelectedIndexChanged="rd1_selectedIndexchanged" AutoPostBack="true">
    <asp:ListItem Text="a" Value="a"></asp:ListItem>
    <asp:ListItem Text="b" Value="b"></asp:ListItem>
    <asp:ListItem Text="c" Value="c"></asp:ListItem>
    </asp:RadioButtonList>
   

code :
protected void Set()
    {
        string livingArea = "";
        // Setup Living Area
        switch (rd1.SelectedItem.Text)
        {
            case "a":

                livingArea = "Rental Properties Listing";
                break;

            case "b":

                livingArea = "Home Property Listing";
                break;

            case "c":

                livingArea = "Apartment Property Listing";
                break;
            default:
                livingArea = "";
                break;
        }

        Response.Write(livingArea);

It appears to me that the OP is trying to evaluate the Checked
property of different RadioButton controls.
