  exception handling

  May 24, 2012 06:54 AM|LINK

   I have found a goodway of exception handling

    obj.MethodName(objpModel, ref objExceptionsBE);

                      foreach (Exception objException in objExceptionsBE)
                      {
                          if (objException.Notifier == NotifierType.Error)
                          {
                              isSuccessFull = false;
                              lblErrMsg.Text = "This request has been failed. Please double check your criteria or contact technical support!";

                          }
                          if (objException.Notifier == NotifierType.Warning)
                          {
                              isSuccessFull = false;
                              lblErrMsg.Text = "This request has been failed. Please double check your criteria or contact technical support!";

                          }

                      }
                      if (isSuccessFull)
                      {
                          lblErrMsg.Text = "This request has been completed successfully!";
                          this.lblErrMsg.Style.Add("color", "#00C000");
                      }

   

   during dac execution

  when success:

  objExceptionsBE.Add(new ExceptionBE("", strMsg,Entity.BE.NotifierType.Success));

  when failue

  objExceptionsBE.Add(new Entity.BE.ExceptionBE("", ConfigurationSettings.AppSettings["Generic_Error_Message"].ToString(), Entity.BE.NotifierType.Error));

  in web config

  <add key="Generic_Error_Message" value="some error!"/>
   

   

   

   

   

  
  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using System.Collections;

  namespace Entity.BE
  {
      public class ExceptionBE
      {

          #region Private Variables
          private NotifierType _notifier;
          private string _code;
          private string _message;
          #endregion

          public ExceptionBE()
          {
              this._code = string.Empty;
              this._message = string.Empty;
              this._notifier = NotifierType.Error;
          }

          public ExceptionBE(string code, string message, NotifierType notifier)
          {
              this._code = code;
              this._message = message;
              this._notifier = notifier;
          }

          public string Code
          {
              get { return _code.Trim(); }
              set { _code = value.Trim(); }
          }

          public string Message
          {
              get { return _message.Trim(); }
              set { _message = value.Trim(); }
          }

          public NotifierType Notifier
          {
              get { return _notifier; }
              set { _notifier = value; }
          }
      }

      public class ExceptionsBE : CollectionBase
      {
          public virtual ExceptionBE this[int index]
          {
              get { return (ExceptionBE)this.List[index]; }
              set
              {
                  if (value.GetType() == typeof(ExceptionBE))
                  {
                      this.List[index] = value;
                  }
              }
          }

          public virtual void Add(ExceptionBE exceptionBE)
          {
              this.List.Add(exceptionBE);
          }
      }
      public enum NotifierType
      {
          Success = 0,
          Error = 1,
          Warning = 2
      }
  }
