Random(); How much accurate ?

[hisheeraz]

Hello friends.
This Random(); method in C# System library. How much accurate is it? Does it really Generates random Numbers? I have looked into the previous threads and found some people saying this is not really a random generator...use Cryptography. what difference it makes?

And from memory i can tell there was a rand(); functionin c++ that generated random number number but it generated the same number all the time unless i actually made time involved with that function.

I donot see any time invilvement with this Random(); method in C#.
So is it really Random Number Generator? if yes How accurate? and if no then where does it go Wrong?

Thanks and Regards

Can you define how accurate?

And I think you are looking for the random class. Have a look here, appears to be a good read. Short but sweet:

Hope it helps,

Random is a pseudo-random number generator. Eventually, if you request enough numbers, it will repeat.

If you want really good random numbers, investigate the RNGCryptoServiceProvider in the System.Security.Cryptography namespace.
