Parameters with UnityAction ( eg on value change )

Unity Engine
1

Struggling for a while with this, hoping someone can help. The code below works fine with a button component (but) for the onClick event.

MethodInfo inf = UnityEventBase.GetValidMethodInfo(script, "Click", new System.Type[] { });
if (inf != null)
{
     UnityAction execute = () => inf.Invoke(script, null);
     but.onClick.AddListener(execute);  
}

What i’m trying to work out is how to implement this for a scrollbar component with on value changed, as this involves a float parameter. Any help appreciated.

        MethodInfo inf = UnityEventBase.GetValidMethodInfo(this, "ValueChanged", new Type[] { typeof(float) });
        if (inf != null)
        {
            UnityAction<float> execute = (newValue) => inf.Invoke(this, new object[] { newValue });
            scrollbar.onValueChanged.AddListener(execute);
        }
...
    public void ValueChanged(float newValue)
    {
        Debug.Log(newValue);
    }
