How to check if the flags enum value has/contains other flags enum values in c#?

Description:For example I have Following flags enum and I have stored a number 7 in the database now I have to check if 7 contains the requested number let say 3(which is for OptionOne and OptionTwo) it should return true, in this way I have to compare a single int value with a single int value for the following flag enum.


[Flags]
public enum MyFlagsEnum
{
        None = 0,
        OptionOne = 1,
        OptionTwo = 2,
        OptionThree = 4,
}

You can easily check that by using the following code


int valueFromDatabase = 7;
int requestedValue = 3;
if (((MyFlagsEnum)valueFromDatabase).HasFlag((MyFlagsEnum)requestedValue)) 
{ 
    //perform your operations here
    return true;
}
else
{
    return false;
}
