Is there a fast and non-fancy C# code/algorithm to compress a string of comma separated digits close to maximum info density?
In a nutshell, I programmed myself into a corner by creating a CLR aggregate that performs row id concatenation, so I say: select SumKeys(id), name from SomeTable where name='multiple rows named this' and I get something like: SumKeys name -------- --------- 1,4,495 multiple rows named this But it dies when SumKeys gets > 8000 chars and I don't think I can do anything about it. As a quick fix (it's only failing 1% of the time for my application) I thought I might compress the string down and I thought some of you bright people out there might know a slick way to do this. Something like base64
