cast or convert from a string to an ENUM

[Jose Luis Lominchar]

Is there a way to cast or convert from a string to an ENUM.

This is a simplification of the problem:

enum ENUM_OPS {
   BUY = 1, SELL = 2
};

string sVal = "BUY";

ENUM_OPS eVal;

//eVal = (ENUM_OPS)sVal; //Doesnt works
//eVal = EnumToString(sVal); //Doesnt works

Which is the proper way to assign sVal to eVal?

Thanks!

ENUM_OPS eVal = BUY;
