C# 类型'；系统Linq.IQueryable`1<；T0>'；在未引用的程序集中定义

尽管引用已经存在，或者是构建过程中的默认部分，我还是 得到

错误1在未引用的程序集中定义了类型“System.Linq.IQueryable”“1”。必须添加对程序集“System.Core，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089”的引用

错误2在未引用的程序集中定义了类型“System.Linq.IQueryable”。必须添加对程序集“System.Core，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089”的引用

错误3在未引用的程序集中定义了类型“System.Linq.IQueryProvider”。必须添加对程序集“System.Core，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089”的引用

在

分区上

变量名

public System.Data.Linq.Table<Division> Divisions
{
   get
     {
         return this.GetTable<Division>();
     }
}

这是一个破VS版本的实例，还是我缺少了什么？我是不是一开始就搞错了，忘了说“克拉图·维拉塔·尼托”？如果它能够完成应用程序的构建，我会发布一个堆栈跟踪。谢谢你的帮助

确实是System.Core.dll，请查看官方msdn链接

您的项目没有引用System.Core，或者引用已损坏。解决这个问题。

klaatu verata nicto

是什么意思？klaatu verata nikto来自《地球静止的日子》和《黑暗之军》两部经典之作。推荐。这句话是开玩笑的，与实际问题无关。我已经试着添加了那个参考。我不喜欢它。表示“无法添加对'System.Core'的引用。此组件已被生成系统自动引用。”因此。。。引用它有什么诀窍吗？在csproj文件中添加一行，告诉它
