C# seed random with time
WebAug 6, 2024 · 1. I want to generate a random seed based on a string value (which is ~32 characters long). I don't want to use string.GetHashCode () since I may later will need a working implementation in another language (C++, Python, JavaScript) (Yes I will need to get rid of Random () too then and all other .NET classes). I also want the whole input … WebJul 19, 2016 · To a large degree, this depends on how much random output you need. I'm assuming quite a lot, since you're talking about already having 128 or 256 bytes of random data to seed it with, and you are correct that System.Random is not good enough for this.. I'm hesitant to recommend options, because this entire design pattern is fraught with …

Random Using Next: 303739907. This value is random, so your number will likely be different. WebThe goal is to generate "random" outputs for a fixed integer input, but (and this is the clincher) to generate the same random output every time the same random input is put in.

WebFeb 17, 2024 · An ID or user name could be based on random data. The Random class in C# helps here—it is easy to use and fast. For using the Random class, the important part to remember is that you should create the class once. Then reuse it to get a random stream of numbers. ...

WebHere's an example of how to create a Random object with a seed value based on the current time: csharpRandom random = new Random(DateTime.Now.Millisecond); In this example, we're using the current time to generate the seed value for the Random object. By using a value that changes between runs, we can ensure that the random number …
WebFeb 18, 2013 · Viewed 9k times. 1. I have a pseudorandom number generator (PRNG) with nice properties which uses six UInt32 s as state. I need to come up with a reasonable way to seed it. Two obvious possibilities are: 1) generate six random numbers using System.Random and use them as seeds; 2) generate two GUID s with Guid.NewGuid (). WebThe parameterless constructor for Random takes the current date and time as the seed - and you can generally execute a fair amount of code before the internal timer works out that the current date and time has changed. Therefore we're using the same seed repeatedly - and getting the same results repeatedly.
WebThe seed is randomly initialized at startup (see Random for more information on this) but if you want to randomize it later on, you can use Random.InitState ( (int)DateTime.Now.Ticks). The seed cannot be retrieved once set - the pseudorandomization algorithm stores its internal state in a more complex set of numbers.
