以下是整个SqlHelper的Demo:

         public Result<List<ArticleDTO>> GetIndexArticleList(int count, int userID)
{
var exp = DbUtilityFactory.GetDbUtility().GetSqlExpression<ArticleEntity>();
exp.Where(a => a.userID == userID);
exp.OrderByDescending(a=>a.articleDate);
var data = DbUtilityFactory.GetDbUtility().Paged<ArticleEntity>(a=>a.articleDate,,);
if(data.Any())
{
return new Result<List<ArticleDTO>>()
{
IsSuccess = true,
ReturnMessage = "成功",
ReturnValue = data.Select<ArticleEntity, ArticleDTO>(a => new ArticleDTO()
{
articleAbstract = a.articleAbstract,
articleDate = a.articleDate,
articleID = a.articleID,
articleTitle = a.articleTitle
}).ToList()
};
}else
{
return new Result<List<ArticleDTO>>()
{
IsSuccess = false,
ReturnMessage = "没有记录"
};
}
}

比如在运行到第5行exp.OrderByDescending(a=>a.articleDate)时:
