LINQ to SQL的 - 没有可用的Add方法 [英] LINQ to SQL - No Add method available

问题描述

我创建了一个LINQ to SQL的DataContext的，在一个单一的数据表。我想简单地插入新记录到该表中。我穿过来的问题是LINQ是不是提供了一个Add方法在新的记录来传递。我见过无数的例子，有一个Add方法，但我似乎无法得到它。我是彻底失去了一些东西或者是其他什么东西？

I have created a LINQ to SQL datacontext with a single datatable in it. I am trying to simply insert a new record into that table. The problem I am coming across is LINQ is not offering an Add method to pass in the new record to. I have seen countless examples where there is an Add method, but I can't seem to get it. Am I completely missing something or is it something else?

using (praetoriaTestDataContext db = new praetoriaTestDataContext())
{
    PageHit hit = new PageHit();
    hit.DateViewed = DateTime.Now;
    hit.Page = "test";

    db.PageHits.Add(hit); //Add method is not available!
    db.SubmitChanges();
}

谢谢！

Thanks!

推荐答案

表的添加和删除方法已更名为InsertOnSubmit和DeleteOnSubmit。

Table's Add and Remove methods have been renamed to InsertOnSubmit and DeleteOnSubmit.

db.PageHits.InsertOnSubmit(hit);
