Linq to SQL中的模糊查询

一、

query = from c in tbs
where c.sx != "类别" && c.path_tbname.Contains(tName.Text)
orderby c.id
select c;

二、

IList<string> list = new List<string>();
list.Add("hello the world");
list.Add("hello world");
var result = from t in list
where t.Contains("the")
select t;
foreach (string t in result)
Console.WriteLine(t);
//结果: hello the world

三、

需要引入 System.Data.Linq.SqlClient 命名空间

var query = from c in ctx.Customers
where SqlMethods.Like(c.City, "%ab%")
select c;
