Fixing Format Exceptions without using Try Catch

[ASPNETnewbie]

Does anyone know How best to deal with a FormatException Error without using a try catch Statement?

If it is truely an error then you need to catch it in the catch block, however you should never control flow using Try/Catch statements. Is the error something that you expect to happen?

I'm not too sure what causes a FormatException error. Could you post some code and give an example of when the error would be thrown?

Sample of code causing error

this.State.Items.Add(new ListItem(state.Ab,state.ID.ToString()));

where State is an enumerated type

I don't know what state.Ab is, but you may try adding a .ToString on the end of that as well.

State.AB is already a string too. What I have though is this

this.State.Items.Add(new ListItem(state.Ab,state.ID.ToString("d")));

I added the "d" for formating the information... is that right? I mean since the ID is an integer

The parameters to the New ListItem are strings so the formatting won't matter. Trace through in the debugger and see what values actually exist for state.Ab AND state.ID.ToString(). Probably not text as you expect, but a enum that needs to be converted.

That basically fixed it. Thanks
