convert std::string to enum

14
Hi,
Converting enum to strings is simple. Just we can use the enum as the i ndex to get the string from an array of strings.

But how do I convert string to enum. Should I need to compare with every string in the array and return the enum when it matches.

Whats the efficient way to do this?

Thanks

Nope. An enum is a named integer value. To return BLUE you would have to compare to "BLUE".

i have an enum called

enum companies
{
microsoft,
ibm,
oracle
}

to get the corresponding integer enum value :--

int int_value = (int)Enum.Parse(typeof(companies), "microsoft", true);

to convert integer enum value to its corresponding string :--

object s =Enum.Parse(typeof(companies), Convert.ToString(int_value));
string st = Convert.ToString(s);

Your example is Microsoft Managed C++. My reply was ANSI C++.
