转换IList<T>为List<T>

/**//// <summary>
    /// 转换IList<T>为List<T>
    /// </summary>
    /// <typeparam name="T">指定的集合中泛型的类型</typeparam>
    /// <param name="gbList">需要转换的IList</param>
    /// <returns></returns>
 public static List<T> ConvertIListToList<T>(IList gbList) where T : class
    {
        if (gbList != null && gbList.Count > 1)
        {
            List<T> list = new List<T>();
            for (int i = 0; i < gbList.Count; i++)
            {
                T temp = gbList[i] as T;
                if (temp != null)
                    list.Add(temp);
            }
            return list;
        }
        return null;
    }


另一中方法

private List<T> Convert(System.Collections.IList listObjects)
{
    List<T> convertedList = new List<T>();

    foreach (object listObject in listObjects)
    {
        convertedList.Add((T)listObject);
    }

    return convertedList;
}
