ilist 与list 之间的相互转换

1>  将list转化为ilist

 

#region 转化list为ilist集合
    private IList<T> ConvertToIList(System.Collections.Generic.List<T> listObjects)
    {
        IList<T> convertedList = new List<T>();

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

        return convertedList;
    }

    #endregion

 

#region 转化ilist为list集合
        private IList<adminListInfo> ConvertToIList(System.Collections.Generic.List<adminListInfo> listObjects)
        {
            IList<adminListInfo> convertedList=new List<adminListInfo>();

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

            return convertedList;
        }

        #endregion

2> 将ilist 转化为list

 

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;
}
