Script component error

Script component error

I'm passing a dataset (query) in SSIS to a script component. However I'm
getting an error on execution "Script component has encountered an
exception in user code:". I've found other posts with this same error but
none of them apply to my error.
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
string[] addresses = (Row.shcladdress).Split(';');
}
