How do you convert a string into an enum

object Enum.Parse(System.Type enumType, string value, bool ignoreCase)

Define Enum:

enum Weekday
   {
      Sunday,
      Monday,
      Tuesday,
      Wednesday,
      Thursday,
      Friday,
      Saturday
  }

 Weekday wd = null;

string weekDay = "Monday";

First check is it enum that you are going to convert exists or not, otherwise it will
return an exception:

if (Enum.IsDefined(typeof(Weekday), weekDay))
wd = (WeekDay) Enum.Parse(typeof(Weekday), weekDay, true);
else
Response.Write("Enum does'not exist.");
