How will clean memory...

Hi

@YuriKuznetsov

I have following class

public class Node : NSObject
{
public Int64 Fid { get; set; }
public Int64 Pid { get; set; }
public string Name { get; set; }
public State State { get; set; } = State.Off;
public Node Parent { get; set; }
public string Path { get; set; }

    public IList<Node> leaf = new List<Node>();

    public IList<Node> NodeList
    {
        get { return this.leaf; }
        set { this.leaf = value; }
    }

    public bool HasChildren
    {
        get { return (this.leaf.Count > 0); }
    }

    public Node(Node parent)
    {
        Parent = parent;
    }
    public Node(Node parent, string path, string fldname, Int64 fldid, Int64 fldpid)
    {
        Parent = parent;
        Path = path;
        Name = fldname;
        Fid = fldid;
        Pid = fldpid;
    }
    public void SetStateToChildren(State state)
    {

    }

    public void SetStateToParent(State state)
    {

    }
}

I am allocating memory to root node using

nodeTree = new Node(null, tmp, strPath, 501, 0);//Node(Node parent, string path, string fldname, Int64 fldid, Int64 fldpid)

and all other child node

nodeTree.NodeList.Add(new Node(nodeTree, tmp, strFolderName, FldId, ParentId));//Node(Node parent, string path,string fldname,Int64 fldid, Int64 fldpid)

I want to delete each data members and each node to clean the memory. How will clean the memory.
