Sharepoint LINQ类型或命名空间名称'Linq‘在命名空间'System’中不存在

Question

我在我的Win7家庭高级版64位笔记本电脑上安装了SharePointFoundation2010。

我使用布局文件夹复制我的aspx页面，其中有两个导入使用System.Linq;，Microsoft.SharePoint.Linq;I我得到这个错误

类型或命名空间名称“Linq”在命名空间“System”中不存在(是否缺少程序集引用？)但即使添加了许多论坛中建议的以下几行

我更改了C：\inetpub\wwwroot\VirtualDirecilds80目录下的web.xml文件，添加了以下内容

    <add assembly="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
    <add assembly="Microsoft.SharePoint.Search, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />


    <add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
    <add assembly="System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
    <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
    <add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
    <add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add assembly="System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
    <add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add assembly="System.Web.Extensions.Design, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

  </assemblies>

这是在</configuration>之前

<system.codedom>
    <compilers>
        <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
            <providerOption name="CompilerVersion" value="v3.5"/>
            <providerOption name="WarnAsError" value="false"/>
        </compiler>
        <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" warningLevel="4" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
            <providerOption name="CompilerVersion" value="v3.5"/>
            <providerOption name="OptionInfer" value="true"/>
            <providerOption name="WarnAsError" value="false"/>
        </compiler>
    </compilers>
</system.codedom>

请指导

我在我的工作框中选中了这一点:你需要在web中包含的所有内容。配置是System.Core程序集和一个compiler元素，CompilerVersion设置为"v3.5“。

这将进入Configuration/system.web/compilation中

<assemblies>
  <add assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
  <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  <add assembly="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
  <add assembly="Microsoft.SharePoint.Search, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
  <add assembly="Microsoft.Office.Access.Server.UI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
  <add assembly="Microsoft.SharePoint.Publishing, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
  <add assembly="Microsoft.Office.Server.Search, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

  <!-- Additional Assembly -->
  <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
</assemblies>

这将放入/Configuration/

<system.codedom>
  <compilers>
    <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <providerOption name="CompilerVersion" value="v3.5" />
      <providerOption name="WarnAsError" value="false" />
    </compiler>
  </compilers>
</system.codedom>

程序集System.Data.Linq和System.Data.Linq不是必需的。

找到了！由于它的aspx部署在布局文件夹中，因此必须按照上面的建议更改布局文件夹中的web.config。感谢所有人
