I have this enum:
[Flags]
public enum Countries
{
None = 0,
USA = 1,
Mexico = 2,
Canada = 4,
Brazil = 8,
Chile = 16
}
I receive in input strings like these:
string selectedCountries = "Usa, Brazil, Chile";
how to convert it (in C#) back to:
var myCountries = Countries.Usa | Countries.Brazil | Countries.Chile;
Use Enum.Parse .
eg Countries c = (Countries)Enum.Parse(typeof(Countries), "Usa, Brazil...");
This seems to work for me assuming your country string is separated by a comma:
private static Countries ConvertToCountryEnum(string country)
{
return country.Split(',').Aggregate(Countries.None, (seed, c) => (Countries)Enum.Parse(typeof(Countries), c, true) | seed);
}
Actually I realized that it is easier than what i thought. All I need to do is convert that string into an int, in my case, or a long in general, and cast it to Countries. It will convert that number into the expected format. In other words:
(Countries) 25 = Countries.Usa | Countries.Brazil | Countries.Chile;
