srand((unsigned)(time(NULL))); (rand())/(RAND_MAX/2) - 1 C# equivalent

Question

What is the c# equivalent of the following c++:

srand((unsigned)(time(NULL)));
weight=(double)(rand())/(RAND_MAX/2) - 1;

Answer 1

The paramaterless constructor for Random uses "a time-dependent default seed value" so all you need is:

Random rnd = new Random();
return rnd.Next(-1, 1);
