Bitwise operations

can it be done in C#? Any help, I new to programming and would like to use the helpful feature.


const ulong VOLATILITY_DISPLAY_PERFORMANCE =1;
const ulong VOLATILITY_DISPLAY_STANDARDDEVIATION =2;
const ulong VOLATILITY_DISPLAY_ARITHMETICMEAN =4;
const ulong VOLATILITY_DISPLAY_EFFICIENCYINDEX =8;
const ulong VOLATILITY_DISPLAY_SHARPE =16;
const ulong VOLATILITY_DISPLAY_VARIANCE =32;
const ulong VOLATILITY_DISPLAY_ALPHA =64;
const ulong VOLATILITY_DISPLAY_BETA =128;
const ulong VOLATILITY_DISPLAY_TREYNOR =256;


long value = VOLATILITY_DISPLAY_PERFORMANCE + VOLATILITY_DISPLAY_SHARPE;

/8it throws a compiler error for next line*/
if(value & VOLATILITY_DISPLAY_SHARPE) /* == TRUE */
{
/*DO SOME THING*/
}

Try if(value & VOLATILITY_DISPLAY_SHARPE == VOLATILITY_DISPLAY_SHARPE)
