Best way to check if a drop down list contains a value?

Question

There are two methods that come to mind:

You could use Contains like so:

if (ddlCustomerNumber.Items.Contains(new 
    ListItem(GetCustomerNumberCookie().ToString())))
{
    // ... code here
}

or modifying your current strategy:

if (ddlCustomerNumber.Items.FindByText(
    GetCustomerNumberCookie().ToString()) != null)
{
    // ... code here
}

EDIT: There’s also a DropDownList.Items.FindByValue that works the same way as FindByText, except it searches based on values instead.
