Lambda Expression

Question

Hi Guys,

 

 Please help me to build Lambda expression for below C# for loop  , Because the below for loop getting high CPU..

 

 

for (int i = 1; i <= dQuantity; )

{

double dlRnd = rnFirst.NextDouble();//with seed

if (dlRnd < 0.0001)

dlRnd += 0.012;

//string strRndFirstDgt = dlRnd.ToString().Substring(2, iFirstPinLng);

long strRndFirstDgt = ExtractDigits(dlRnd, 2, iFirstPinLng);

//----Second Rnd ------ 0.6 91979 52919 26617

double dlSecondRnd = rnSecond.NextDouble(); //Without Seed. 58535 03461 123

if (dlSecondRnd < 0.0001)

dlSecondRnd += 0.012;

long strRndSecondLastsixDgt = ExtractDigits(dlSecondRnd, dlSecondRnd.ToString().Length - iSecondPinLng, iSecondPinLng);

//string strRndSecondLastsixDgt1 = dlSecondRnd.ToString().Substring(dlSecondRnd.ToString().Length - iSecondPinLng, iSecondPinLng);

long conCan = Convert.ToInt64(strRndFirstDgt.ToString() + Convert.ToString(strRndSecondLastsixDgt));

long temp;

temp = Convert.ToInt64(conCan) + DateTime.Now.Ticks; //addition to pin+ datetime Ticks

int intRndThird = rnThird.Next(1, 10);//To avoid the prefix value 0's;

// string conCanRnd = intRndThird.ToString() + Convert.ToString(ExtractDigits(temp,temp.ToString().Length - pinLength, pinLength - 1));

long conCanRnd = Convert.ToInt64(stInt.ToString() + intRndThird.ToString() + (temp.ToString().Substring(temp.ToString().Length - pinLength, pinLength - 1)));

// long sessionconcatpins = Convert.ToInt64(stInt.ToString() + conCanRnd); // Append Concurent User Hit Count in to PINS

if (lstpins.Add(conCanRnd))

i++;

if (i % 100 == 0)

{

lngDateTicker = DateTime.Now.Ticks;

strSeedLastNineDgt = lngDateTicker.ToString().Substring(7, 9);

rnFirst = new Random(Convert.ToInt32(strSeedLastNineDgt));

}

}
