Answer 1

Change your catch to be catch (Exception ex) and you can then use Response.Write(ex.Message)

Ideally, you would have different catches for different exception types. This is a bucket approach to catching all exceptions.

Answer 2

Change your catch to catch (SqlException ex) and catch (Exception ex)

        catch (SqlException ex)
        {
            StringBuilder errorMessages = new StringBuilder();
            for (int i = 0; i < ex.Errors.Count; i++)
            {
                errorMessages.Append("Index #......" + i.ToString() + Environment.NewLine +
                                     "Message:....." + ex.Errors[i].Message + Environment.NewLine +
                                     "LineNumber:.." + ex.Errors[i].LineNumber + Environment.NewLine);
            }
            WriteToLog(FileLog, "SQL Error message: " + errorMessages.ToString() + Environment.NewLine);
            WriteToLog(FileLog, "Process has been finished with errors." + Environment.NewLine);
        }
        catch (Exception ex)
        {
            WriteToLog(FileLog, "Error message: " + ex.Message + Environment.NewLine);
            WriteToLog(FileLog, "Error stack trace: " + ex.StackTrace + Environment.NewLine);
            WriteToLog(FileLog, "Process has been finished with errors." + Environment.NewLine);
