C# reflection cast to variable type

Just started studying reflection and im having a lot of issues. I want to cast to find the type of properties and then set them. So i wanted to cast to these properties type.

protected override object Load(SqlDataReader dr)
        {
            object item = Activator.CreateInstance(klass);



            foreach (var p in klass.GetProperties())
            {
                MethodInfo pSet = p.GetSetMethod();
                Type pType= p.PropertyType;
                object setParam = dr[p.Name]; 
                object[] paramArray = (object[])Array.CreateInstance(pType, 1);
                paramArray[0] = setParam;
                pSet.Invoke(item, paramArray);
            }
            return item;
        }
