查找包含linq的所有文章

本文关键字：文章 包含 linq 查找 | 更新日期: 2023-09-27 18:10:47

尝试学习Linq，但在这里碰壁。

我试图找到包含多个字符串的所有文章，但不确定如何使用。包含在传递列表时。

private void SearchArticles()
{
    AdminEntities db = new AdminEntities();
    var searchStrs = new List<string> {"search_string1", "search_string2"};
    var artListfull = db.view_M02Articles_SearchPublished(0, "").ToList();
    var artList = artListfull.FindAll(n => n.Bodytext.Contains(searchStrs));
    Label1.Text = artList.Count.ToString();
    Repeater1.DataSource = artList;
    Repeater1.DataBind();
}

这里的正确语法是什么?

[Edit]假设BodyText为string类型

你可以试试:

//the article body must contain "ALL" the search terms
var artList = artListfull.Where(art => searchStrs.All(art.BodyText.Contains));

或

//the article body must contain "At least one" of the search terms
var artList = artListfull.Where(art => searchStrs.Any(art.BodyText.Contains));

[编辑2]替换由art.BodyText.Contains str => art.BodyText.Contains(str)

With 

var artList= (from art in artFullList
              from search in searchStrs 
              where art.Bodytext.Contains(search)
              select art).ToList();

var artList = artListfull.Where(a => searchStrs.Any(s => a.Bodytext.Contains(s)))
                         .ToList();
