在您的表单代码覆盖此属性，它应该做的招适合你。

I am creating some always-on-top toasts as forms and when I open them I'd like them not to take away focus from other forms as they open. How can I do this?

Thanks

protected override bool ShowWithoutActivation
{
    get
    {
        return true;
    }
}

Override this property in your form code and it should do the trick for you.
