CS0019: Operator '==' cannot be applied to operands of type 'string' and 'int'

Question

Hi,

I have a DropDownList named ddlCluster, and I want to do a simle test:

if (ddlCluster.SelectedValue == 0)

{

     //some stuff goes here

}

Now this is returning this error: CS0019: Operator '==' cannot be applied to operands of type 'string' and 'int'

??????

With VB.NET this seems to work. Any thoughts?

hi,

I solved it by turning 0 into a string:

if (ddlCluster.SelectedValue == "0")

 

Thanks for your time

use ddlCluster.SelectedIndex instead of SelectedValue

I'd use string.Compare instead.

if (string.Compare(ddlCluster.SelectedValue, "0") != 0)

When I create DropDownLists I will dynamically add a ListItem with a value of "-1". If AutoPostBack is enabled in the handler I will have something like:

if (!ddlCluster.Items.FindByValue("-1").Selected)
