如何在MVC LINQ中获取所有值 [英] How to get all values in MVC LINQ

问题描述

使用firstordefault获取特定记录。但我需要所有值，如何获取所有值？得到错误：

Hi,using firstordefault getting particular record.But i need all values ,How to get all values ? getting error:

The method or operation is not implemented.

Performane_QA是表名。我需要更新值，但值或不更新。



我尝试过：



控制器

Performane_QA is table name. I need update values but values or not updating.

What I have tried:

Controller

Performane_QA updateddata1 = (from c in bics.Performane_QA
                             where c.PerformanceId == updateddata.PerformanceId
                                             select c).ToList();

推荐答案

List<Performane_QA> updateddata1 = (from c in bics.Performane_QA
where c.PerformanceId == updateddata.PerformanceId
select c).ToList();


to get data
---------
foreach(Performane_QA v in updateddata1)
{

string StrPerformanceId=v.PerformanceId;
}


or 

var updateddata1 = (from c in bics.Performane_QA
where c.PerformanceId == updateddata.PerformanceId
select c).ToList();

to get data
---------
foreach(var v in updateddata1)
{

string StrPerformanceId=v.PerformanceId;
}

var uprowsdetails = bics.Performane_QA.Where(t => t.PerformanceId == updateddata.PerformanceId).ToList();


        uprowsdetails.ForEach(a => a.Field name = value);

           db.SaveChanges();
