Question

Questions:

1. Can I deadlock this code? Does the IsMouseInside property is thread safe?
2. Does the use of the copy variable make sense?

PS: UI thread updates IsMouseInside. Another thread will read its value some times

    public Class Test    
    {

    private readonly object isMouseInsideLocker = new object();
    private bool isMouseInside = false;

    public bool IsMouseInside
    {
        get
        {
            bool copy;
            lock (this.isMouseInsideLocker)
                copy = this.isMouseInside;
            return copy;
        }
        set
        {
            lock (this.isMouseInsideLocker)
                this.isMouseInside = value;
        }
    }

    private void lblProcessTime_MouseEnter(object sender, EventArgs e)
    {
        IsMouseInside = true;
    }

    private void lblProcessTime_MouseLeave(object sender, EventArgs e)
    {
        IsMouseInside = false;
    }
}

Answer 1

1. No, you can’t.
2. It doesn’t. Just return isMouseInside;
