如何使用 Action<Action<object>, object> ?这是正确的方法吗?

how can use Action<Action<object>, object> ? Is this the right way?

为每个对象创建一个方法很麻烦。
同类型的每个方法只用一个动作不就可以吗?

    Action<Action<object>, object> action;

    private void init_Shown(object sender, EventArgs e)
    {
        // how write code?
        action = (a, o) =>
        {
            //Action<object>
            a(o);
        };
    }

    // this method used by another thread
    private void test(object obj)
    {   
        // i want this like. and use other methods.
        this.Invoke(action, listbox.Items.Add, obj);
    }

这是代码

    private void init_Shown(object sender, EventArgs e)
    {
        listboxAdd = (obj) =>
        {
            listbox.Items.Add(obj);
        };
    }

    // this method used by another thread
    private void test(object obj)
    {
        this.Invoke(listboxAdd, obj);
    }

listbox.Items.AddAction<object>具有相同的签名,因此编译器可以在需要Action<object>时直接使用它。这应该有效:

private void test(object obj)
{
    this.Invoke(listbox.Items.Add, obj);
}
