I'm trying to writing a method that parses a string parameter into an enum. The enum's type is also determined by a parameter. This is what I've started with:
public static type GetValueOrEmpty(string text, Type type)
{
if (!String.IsNullOrEmpty(text))
{
return (type)Enum.Parse(typeof(type)value);
}
else
{
// Do something else
}
}
Obviously this won't work for a number of reasons. Is there a way this can be done?
You can make it generic instead, if you know the type at compile-time:
public static T GetValueOrEmpty<T>(string text)
{
if (!String.IsNullOrEmpty(text))
{
return (T) Enum.Parse(typeof(T), text);
}
else
{
// Do something else
}
}
If you don't know the type at compile-time, then having the method return that type won't be much use to you. You can make it return object of course:
public static object GetValueOrEmpty(string text, Type type)
{
if (!String.IsNullOrEmpty(text))
{
return Enum.Parse(type, text);
}
else
{
// Do something else
}
}
If neither of these are useful to you, please give more information about what you're trying to achieve.
You need to use a generic method. Something like this should do the trick:
public static TEnum ParseEnum<TEnum>(string s)
{
return (TEnum)Enum.Parse(typeof(TEnum), s);
}
EDIT: Fixed typo in code...
