How Can I Generate Distinct Random Numbers in a Static Method Using C#?

Generating Distinct Random Values by Seeding the Random Class

The challenge you face when encountering duplicate random values in a static method is that the Random class defaults to a seed of 0. Consequently, subsequent calls to Next() within the method will produce the same sequence of values.

To resolve this issue, it is essential to explicitly seed the Random class with a unique value. One effective approach involves utilizing the GetHashCode() method of the Guid class to generate a random seed:

Random rand = new Random(Guid.NewGuid().GetHashCode());

This method guarantees a highly randomized seed that changes each time it is called. As a result, the Random class will generate distinct values within the loop, eliminating the issue of repeated random numbers.
