[API Proposal]: Be able to set a Int64 and Int128 seed to Random

[Mrgaton]

Background and motivation

The current System.Random class does not allow initializing with a seed longer than a 32-bit integer. This proposal suggests introducing an API that supports initializing a Random instance with a longer seed (e.g., a byte[] or ReadOnlySpan).

API Usage

new Random(3435734875763456)

If posible add it to net 9

This proposal is not really actionable, as is. When creating an API proposal, please follow the template and fill in the requested info, don't remove sections like you did. At the very least, there should be an actual API proposal, which is entirely missing here. Consider updating your post to include it. You can look at other API proposal that have been approved, as a reference.

"If posible add it to net 9"

Absolutely not possible, since .NET 9 has already shipped.

Looks like a duplicate of #21908

I think the main thing that's missing from the proposal is the motivation behind needing such APIs.

I don't know to do api proposal as i'm not that expert to write nice looking api.

Things are more complicated now when different random algorithms are involved.
Currently, when a seed is provided, Random will choose the "compatible" implementation, which as an algorithm with a fixed 32-bit degree of freedom. It's not meaningful to provide more bits to its seed.

Such overload could potentially add a way to have seeded instances with the new algorithm, which could be potentially nice.
