Hi ,

what should i do? i tried putting return null inside the big catch but it didn't work.

    public str fcn()
    {
        System.Net.WebException webEx;
        System.Net.WebException webExInner;
        System.Exception        ex;
        System.Exception        exInner;
        try
        {   

            //logic 

            str webResponse = this.test();
            return webResponse;
        }
        
        catch(webEx)
        {
            try
            {
                System.Net.HttpWebResponse  webResponse = webEx.Response;
                     
                switch (webResponse.StatusCode)
                {
                    case 409:
                        if(//logic)
                        {
                            //logic
                        }
                        else
                        {
                             error("@label"    " "   webEx.get_Message()); 
                        }
                        break;
                    default:
                             error("@label"   " "   webEx.get_Message());

                }
            }
            catch (webExInner)
            {
                error("label"   " "   webExInner.get_Message());
            }

            catch(exInner)
            {
                error("label"   " "   exInner.get_Message());
            }
            
        }

        catch (Exception::Error)
        {
            
        }

        catch(ex)
        {
            error("@label"   " "   ex.Message);
        }

        finally
        {
            //logic
        }
        
    }

Hi juniorAX,

Try returning at the end of the method. Please try this code and check if that works -

public str fcn() { System.Net.WebException webEx; System.Net.WebException webExInner; System.Exception ex; System.Exception exInner; str webResponse; try { //logic webResponse = this.test(); } catch(webEx) { try { System.Net.HttpWebResponse webResponse = webEx.Response; switch (webResponse.StatusCode) { case 409: if(//logic) { //logic } else { error("@label" " " webEx.get_Message()); } break; default: error("@label" " " webEx.get_Message()); } } catch (webExInner) { error("label" " " webExInner.get_Message()); } catch(exInner) { error("label" " " exInner.get_Message()); } } catch (Exception::Error) { } catch(ex) { error("@label" " " ex.Message); } finally { //logic } return webResponse; }
