DataSet转换成List<>

方法一：

 //DataSet转换成List<ArticleInfo>
        public List<ArticleInfo> GetArticleList(DataSet ds)
         {
             List<ArticleInfo> list = new List<ArticleInfo>();
             for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
             {
                 ArticleInfo model = new ArticleInfo();
                 model.arttime = Convert.ToDateTime(ds.Tables[0].Rows[i]["arttime"]);
                 model.cgyid = Convert.ToInt32(ds.Tables[0].Rows[i]["cgyid"]);
                 model.clicks = Convert.ToInt32(ds.Tables[0].Rows[i]["clicks"]);
                 model.contents = Convert.ToString(ds.Tables[0].Rows[i]["contents"]);
                 model.id = Convert.ToInt32(ds.Tables[0].Rows[i]["id"]);
                 model.img = Convert.ToString(ds.Tables[0].Rows[i]["img"]);
                model.recommend = Convert.ToBoolean(ds.Tables[0].Rows[i]["recommend"]);
                 model.related = Convert.ToBoolean(ds.Tables[0].Rows[i]["related"]);
                 model.title = Convert.ToString(ds.Tables[0].Rows[i]["title"]);
                model.uid = Convert.ToInt32(ds.Tables[0].Rows[i]["uid"]);
                 list.Add(model);
             }
             return list;
         }

方法二：

  public List<ArticleInfo> DataSetToList(DataSet ds)
         {

             foreach (DataRow row in ds.Tables[0].Rows)
             {
                 list.Add(DataRowToModel(row));
             }
             return list;
         }

        /// <summary>
        /// 得到一个对象实体
        /// </summary>

        {
            ArticleInfo model = new ArticleInfo();
            if (row != null)

                if (row["id"] != null && row["id"].ToString() != "")
                {
                    model.id = int.Parse(row["id"].ToString());
                }

                if (row["contents"] != null)
                {

                if (row["title"] != null)
                {
                    model.title = row["title"].ToString();
                }

                if (row["arttime"] != null && row["arttime"].ToString() != "")
                {

                }

                if (row["related"] != null && row["related"].ToString() != "")
                {
                    if ((row["related"].ToString() == "1") || (row["related"].ToString().ToLower() == "true"))
