如何检查行是否已更新(布尔)

问题描述

我有一个小问题
代码:

Hi, I have a small question
code:

public bool SaveChangesAtbildes(string jautajums, string atbilde, string pareizaAtbilde,
           int punkts, int testAtbildesID)
       {
           var saveQueryChangesAtbildes =
               from ch in db.JautājumuAtbildes
               where ch.TestaAtbildesID = testAtbildesID
               select ch;
           var saglabaDatus2 = new JautājumuAtbilde
           {
               Jautājums = jautajums,
               Atbilde = atbilde,
               PareizāAtbilde = pareizaAtbilde,
               Punkts = punkts,
               TestaAtbildesID = testAtbildesID
           };
           db.JautājumuAtbildes.InsertOnSubmit(saglabaDatus2);
           db.SubmitChanges();
           return true;
       }

如果未更改任何行，如何返回"false"?

谢谢！ :)
