C # get random number (randomness class)

Random numbers can be obtained in the range you specify by using random;

Random rd=new random (); int i=rd. Next ();//generates a non-negative integer int j=rd. Next (10);//generates integer int k=rd within 0-9. Next (10,100);//number int m=rd within 10=100. Nextdouble ();//Generate a real type of random number "0,1" within

Note: In the case of high concurrency, the random number may be the same, can be solved by thread sleep ();
