Particle System move to location

I need to move particles to specific location .
I tried to use force but couldn’t find any way to do it
my second attempt was to use ParticleSystem.GetParticles to get all the particles and change their velocity manually.I cant figure what I should put in the array

Get all the particles in an array, do the modification, and don’t forget to assign them back with SetParticles.

I meant do I have to create the particles manually? and if i use the editor from unity how can i access to the array and change it?
