How can I cast int to enum?

Question

How can an int be cast to an enum in C#?

Answer 1

This is an flags enumeration aware safe convert method:

public static bool TryConvertToEnum(this int instance, out T result)
  where T: Enum
{
  var enumType = typeof (T);
  var success = Enum.IsDefined(enumType, instance);
  if (success)
  {
    result = (T)Enum.ToObject(enumType, instance);
  }
  else
  {
    result = default(T);
  }
  return success;
}
