How do I use a particle system?

I want to call upon the particle system when my player dies as an animation, but I don’t know how to do this. It is giving me this error “The type or namespace name ‘Play’ does not exist in the namespace ‘System’ (are you missing an assembly reference?).” I want to be able to have the animation/particle system play when the player dies, how do I make that happen?

This is my code so far:

using System.Collections;

using System.Collections.Generic;
using UnityEngine;

public class DestroyContact : MonoBehaviour {

PlayerController playerMovement;
ParticleSystem animate;
public bool dead;

void Awake()

{

	playerMovement = GetComponent <PlayerController> ();
	animate = GetComponent <ParticleSystem> (); 
}
void Update(){
	
}

	
void OnTriggerEnter (Collider other)
{
	if(other.gameObject.tag == "Floor")
	{
		return;
	}
	if(other.gameObject.tag == "Collider");
	Destroy(gameObject);
	PlayerDead ();
		
}	

void PlayerDead()

{
	
	dead = true;
	playerMovement.enabled = false;
	System.Play(animate);  //this is where it is giving me the error

}

}

First of all, ParticleSystem is not an Animation, so your naming might confuse you later.

Next, try to start the ParticleSystem by:

animate.Play(true);

I changed it to particleSystemPlayer.Play(true); after changing the name from animate to particleSystemPlayer. The error is now gone but how would I make the particle system to play at the position in which the player died at?
