Today I saw an enum parser generator, and I even posted that a single generic class could do the job. But, as that message was lost, I decided to post this trick.
It is a very simple class to Parse enums. It has the advantage that the Parse is already typed to the right enum type and also that it is faster than the normal Enum.Parse.
The entire code is here:
public static class EnumParser<T>
private static readonly Dictionary<string, T> _dictionary = new Dictionary<string, T>();
throw new NotSupportedException("Type " + typeof(T).FullName + " is not an enum.");
string names = Enum.GetNames(typeof(T));
T values = (T)Enum.GetValues(typeof(T));
int count = names.Length;
for(int i=0; i<count; i++)
public static bool TryParse(string name, out T value)
return _dictionary.TryGetValue(name, out value);
public static T Parse(string name)
And to use it, you only need to call:
Notes: It does not have locks but it is thread safe, as after the creation the dictionary is only read (and it supports multiple readers). It does not support enum [Flags] (ok, a single value is supported, but values separated by comma aren't). It also does not support the ignoreCase mode. It is always case sensitive.
I started to program computers when I was 11 years old, as a hobbist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.
At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do they work easier, faster and with less errors.
