Generate Random Number in .NET without using any Inbuilt Functions

Question

I was wondering how the Random functions in every programming language works so I want to generate a number by myself i.e. I don't want to use any inbuilt classes or functions.

Answer 1

For simplicity and speed, it's hard to beat the Xorshift random number generator. Whether it generates a good distribution is another question.

One example in C#: http://www.codeproject.com/KB/cs/fastrandom.aspx

Different languages and environments use different random number generators. As others have pointed out, there are lots of ways to generate pseudo-random numbers.
