Generate random number between 0 to 10000 in c# -

i'm using c# generate 1000 random number between 0 10000. output need 2 decimal places , , dispaly following

1   18.92 2   874.32 3   7182.56 

here code :

            random random = new random();             float randomnumber = random.next(0, 10001);             string rndnumber = randomnumber.tostring("0.00");             (int = 1; i<= 1000; i++)             {                 (int count = 1; count <= 1000; count++)                 {                     writer.write("{0},\n {0:0.0}", count, rndnumber);                 } 

but far output this:

1, 1.02, 2.03, 3.04, 4.05, 5.06, 6.07, 7.08, 8.09, 9.010, 10.011, 11.012

what did missing?

i figure out myself , use double , math.round 2 decimal

here answer:

            random random = new random();                    (int count = 1; count <= 1000; count++)                 {                     double r = math.round((random.nextdouble() * 10001),2);                      writer.writeline("{0} \n {1}",count, r);                 }
