How can I generate a list of 10 random integer numbers in the range between 0 and 100 so that all random numbers are unequal?

RandomInteger, thanks. $\endgroup$– mrzJul 12, 2016 at 14:33 -

3$\begingroup$ @Young I am also surprised by the votes and I agree with you. I feel guilty since I have almost never posted an answer that requires real effort in this community. Perhaps because as a beginner, my knowledge is a subset of many active users. It will still take me sometime to learn before I can make real contributions. $\endgroup$– vaporJul 12, 2016 at 16:21

3$\begingroup$ @Young I'm of the opinion that for a lot of duplicate questions, especially from first time posters (not that that applies here), it's often better to answer and let others worry about marking duplicates. I feel like it may encourage them to come back more, and our community here is not so large as to discourage newbies $\endgroup$– Jason B.Jul 13, 2016 at 1:14

happy fish gave the right answer, but sometimes it's fun to go oldschool. You can use rejection sampling and a While loop
list = {};
While[Length@list <= 10,
list = DeleteDuplicates@Append[list, RandomInteger[100]]]

$\begingroup$ I like this approach as you don't need to generate the full list. A small modification might save a lot of iterations:
While[(l = Length[ids]) < n, ids = DeleteDuplicates[Join[ids, RandomInteger[max, n - l]]]]$\endgroup$– BatracosJan 27, 2021 at 9:11
