Can anyone help me on this. It may be very frustrating for you all. But I want you guys to take a moment to look at the code below and please tell me all the things that are wrong in the below piece of code. You can copy it into your visual studio to analyze this better. You don’t have to make this code compile. My task is to get the following things:
- Most obvious mistakes with this code
- All the things that are wrong/bad practices with the code below
- Modify/Write an optimized version of this code.
- Keep in mind, the code DOES NOT need to compile.
- Reduce the number of lines of code
You should NEVER try to implement something like below:
public List<ValidationErrorDto> ProcessEQuote(string eQuoteXml, long programUniversalID)
{
// Get Program Info.
DataTable programs = GetAllPrograms();
DataRow[] programRows = programs.Select(string.Format("ProgramUniversalID = {0}", programUniversalID));
long programID = (long)programRows[0]["ProgramID"];
string programName = (string)programRows[0]["Description"];
// Get Config file values.
string fromEmail = ConfigurationManager.AppSettings["eQuotesFromEmail"];
string technicalSupportPhone = ConfigurationManager.AppSettings["TechnicalSupportPhone"];
string fromEmailDisplayName = string.IsNullOrEmpty(ConfigurationManager.AppSettings["eQuotesFromDisplayName"])
? null : string.Format(ConfigurationManager.AppSettings["eQuotesFromDisplayName"], programName);
string itEmail = !string.IsNullOrEmpty(ConfigurationManager.AppSettings["ITEmail"])
