Sharepoint的LINQ类型或命名空间名称'的Linq'不存在命名空间'系统'存在 [英] Sharepoint LINQ The type or namespace name 'Linq' does not exist in the namespace 'System'

问题描述

我有SharePoint Foundation 2010的安装在我的Win7家庭premium 64位的笔记本电脑。

I have sharepoint Foundation 2010 installed in my Win7 Home premium 64 bit laptop.

我用的布局文件夹复制到我的aspx页面里面有使用使用System.Linq的两名外援;，Microsoft.SharePoint.Linq;我得到这个错误

I used layouts folder to copy my aspx pages which has two imports using using System.Linq;,Microsoft.SharePoint.Linq;I am getting this error

类型或命名空间名称'的Linq'不存在命名空间'系统'（是否缺少程序集引用？）但是，即使添加以下行的存在在许多论坛建议

The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?) But even adding the following lines as suggested in many forums

我改下C语言中的web.xml文件：\\的Inetpub \\ wwwroot的\\ WSS \\ VirtualDirectories \\ 80，添加以下内容

I changed the web.xml file available under C:\inetpub\wwwroot\wss\VirtualDirectories\80 to add the following content

      
        
        
        

    <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.Web.Extensions.Design, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

  </assemblies>

而在此之前＆LT; /结构＆gt;

<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">

        </compiler>
    </compilers>
</system.codedom>

请指南

推荐答案

我查了这对我的工作中：所有你需要在网络，包括配置与 System.Core程序的组装和使用编译元素中的 CompilerVersion 的设置为V3.5。

I checked this on my work box: All you need to include in the web.config is the System.Core assembly and a compiler element with the CompilerVersion set to "v3.5".

本进入的配置/的System.Web /编译的：

<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>

本进入的 /配置/ 的：

<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>

大会将System.Data.Linq 的和的将System.Data.Linq 的不是必需的。
