I have an array of objects of the following structure:
structure Disk
{
int UID;
String Computer;
}
A computer may have a bunch of shared disks, and a disk may be shared among computers.
I want to find out all the disks common to all the computers. For example, I have computer A, B, and C; Disks 1, 2, and 3.
The disk array is {1,A}, {1,B}, {2,A},{2,B},{2,C},{3,A}.
The result that I want should be the disk 2, because it appears on A, B, and C.
Is there a effective way to achieve this?
With multiple foreach loops it's achievable, but definitely I want a better way. I'm thinking about operations like intersection, but didn't find this in PowerShell.
