小编FAA*_*FAA的帖子

我在linq中有一个查询db表的类,问题是:如何将该数据导出到csv？我已经尝试了链接建议,我正在使用linq2csv,仍然想知道如何通过他们的订单获取列？谢谢!

var usr = from usr in db.User 
select new { usr.UserName, usr.Dept, usr.Name)
MainListView.DataSource = usr; 
MainListView.DataBind();

CsvFileDescription outputFileDescription = new CsvFileDescription
                {
                    SeparatorChar = ',',
                    FirstLineHasColumnNames = true,
                    FileCultureName = "en-US"
                };

                CsvContext cc = new CsvContext();
               string finalPath = mypath + "usr_" + DateTime.Now.ToString  ( "yyyyMMddhhmmssfff" ) + ".csv";
                cc.Write( usr, finalPath, outputFileDescription );

我在Linq有这个代码.任何人都可以提供t-sql.谢谢!

var tsr = from t in db.Tngs
from l in t.TngUsr
from td in t.TngDepts
from u in db.Users
where t.TId == tId && u.UserId == l.UserId && u.Departments.DeptId == td.Departments.DeptId

是左外第二个/第三个？
