C# code

public void ff(Object objInit, Object[] obj, string[] items)
{
    List<string> itemList = new List<string>(items);
    foreach( PropertyInfo pi in objInit.GetType().GetProperties())
    {
        int idx = itemList.IndexOf(pi.Name);
        if (idx >= 0)
        {
            pi.SetValue(objInit, obj[idx], null);
        }
    }
}

A better one :)

C# code

public void ff(Object objInit, Object[] obj, string[] items)
{
    for(int i=0; i < items.Length; i++)
    {
        PropertyInfo pi = objInit.GetType().GetProperty( items[i] );
        if( pi != null)
        {
            pi.SetValue(objInit, obj[i], null);
        }
    }
}
