Create multiple random class with di erent C# with Example

seeds simultaneously 
Two Random class created at the same time will have the same seed value. 
Using System.Guid.NewGuid().GetHashCode() can get a different seed even in the same time. 
Random rnd1 = new Random(); 
Random rnd2 = new Random(); 
Console.WriteLine("First 5 random number in rnd1"); 
for (int i = 0; i < 5; i++) 
Console.WriteLine(rnd1.Next()); 
Console.WriteLine("First 5 random number in rnd2"); 
for (int i = 0; i < 5; i++) 
Console.WriteLine(rnd2.Next()); 
rnd1 = new Random(Guid.NewGuid().GetHashCode()); 
rnd2 = new Random(Guid.NewGuid().GetHashCode()); 
Console.WriteLine("First 5 random number in rnd1 using Guid"); 
for (int i = 0; i < 5; i++) 
Console.WriteLine(rnd1.Next()); 
Console.WriteLine("First 5 random number in rnd2 using Guid"); 
for (int i = 0; i < 5; i++) 
Console.WriteLine(rnd2.Next()); 
Another way to achieve different seeds is to use another Random instance to retrieve the seed values. 
Random rndSeeds = new Random(); 
Random rnd1 = new Random(rndSeeds.Next()); 
Random rnd2 = new Random(rndSeeds.Next()); 
This also makes it possible to control the result of all the Random instances by setting only the seed value for the 
rndSeeds. All the other instances will be deterministically derived from that single seed value.
