How can I access a property that belongs to an instance of a class that I passed into another class?

Question

I have this class

public partial class PhrasesFrame : Frame
{

    public CancellationTokenSource tokenSource1;
    public PhrasesFrameViewModel vm;

    public PhrasesFrame()
    {
        InitializeComponent();
        vm = new PhrasesFrameViewModel(this);
    }

and this view model

public class PhrasesFrameViewModel : ObservableProperty
{

    private readonly PhrasesFrame phrasesFrame;

    public PhrasesFrameViewModel(PhrasesFrame phrasesFrame) {
        this.phrasesFrame = phrasesFrame;
    }

    private void ResetTimer1()
    {
        if (phrasesFrame.tokenSource1 != null)

    }

on the if line where I use the value of tokenSource2 I get a message saying:

Error CS0120: An object reference is required for the non-static field, method, or property 'PhrasesFrameViewModel.phrasesFrame'

Can someone explain what I am doing wrong to me.

You want to use the phrasesFrame’s variable in a static function. A static function can’t use a class’s non-static variable. Just remove the static keyword and it will work.
