为什么VS 2005继续给我“'x'在命名空间'y'中的含义不明确”错误？

标签： .net visual-studio visual-studio-2005 namespaces

Bounty：我会通过PayPal发送5美元，以便为我解决此问题。

我不确定VS设置我已经改变了，或者它是web.config设置还是什么，但我在错误列表中不断收到此错误，但所有解决方案都构建良好。以下是一些例子：

Error   5   'CompilerGlobalScopeAttribute' is ambiguous in the namespace 'System.Runtime.CompilerServices'. C:\projects\MyProject\Web\Controls\EmailStory.ascx  609 184 C:\...\Web\
Error   6   'ArrayList' is ambiguous in the namespace 'System.Collections'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   13  28  C:\...\Web\
Error   7   'Exception' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   37  21  C:\...\Web\
Error   8   'EventArgs' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   47  64  C:\...\Web\
Error   9   'EventArgs' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   140 72  C:\...\Web\
Error   10  'Array' is ambiguous in the namespace 'System'. C:\projects\MyProject\Web\Controls\EmailStory.ascx.vb   147 35  C:\...\Web\

    [...etc...]

Error   90  'DateTime' is ambiguous in the namespace 'System'.  C:\projects\MyProject\Web\App_Code\XsltHelperFunctions.vb   13  8   C:\...\Web\

你可以想象，它真的很烦人，因为代码中到处都有蓝色波浪形下划线，并且在错误列表窗格中过滤掉相关错误几乎是不可能的。我已经检查了默认的ASP.Net web.config和machine.config，但似乎没有任何东西可以脱颖而出。

编辑：以下是发生错误的部分来源：

'Error #5: whole line is blue underlined'
<%= addEmailToList.ToolTip %>

'Error #6: ArrayList is blue underlined'
Private _emails As New ArrayList()

原生图像中应该只有一个mscorlib，对吗？我怎样才能摆脱其他人？

我最近遇到了同样的错误。 以下是我修复它的方法（我希望它也适用于你）：

- 打开项目属性，转到参考部分。

- 删除上一部分对System的引用。

我认为它引用了系统两次，但它只显示一次。因此，这是一个暧昧的参考。

根据你的gacutil输出的结果（感谢你这样做;我认为这有帮助），我想你需要尝试在.NET Framework安装和Visual Studio 2005上运行修复。我不确定如果这样可以修复它，但正如你从gacutil的输出中看到的那样，你没有2.0。

从我的VS2005命令提示符中，我得到：

在寻求帮助诊断编译问题时，发布有问题的源代码通常会有所帮助：）

这些错误实际上意味着指定的名称与另一个名称冲突，编译器无法解决此问题。它确实看起来有点奇怪..

答案 3 :(得分：0)

我也受到了这种打击，特别是System.Data.SqlClient。尝试在项目管理器中取消选中名称空间并手动将它们包含在.vb文件中，就像使用C＃一样：

导入System.Data.SqlClient

答案 4 :(得分：0)

接受一个错误（如ArrayList）并用完全限定名称替换类型（我不确定，但我想这里：System.Collection.ArrayList）。如果错误消失，你真的有一个解决冲突。如果没有，那就是别的了 如果所有解决方案都存在这些错误，那么我建议您清理项目。删除所有已编译的东西（dll，pdb，无论如何），还有阴影缓存的东西。也许它会编译，因为它使用旧版本的东西。

答案 5 :(得分：0)

我知道这听起来很奇怪，但您使用“Build”或“Rebuild”来构建解决方案吗？如果我有这样的有趣问题，解决方案的“全部重建”会有所帮助。

昨天我在VS2005 ASP.NET网站项目中得到了同样的结果：突然之前，在任何先前重要的代码更改中，'x'的加载在命名空间'y'中是不明确的，所有这些都来自非常基本的符号，像EventArgs，Type，DBNull等

直接原因是双重引用的mscorlib，正如我在VS的类视图中看到的那样。我相信，真正的原因是自动Windows Update，它迫使我在几分钟之前重启机器。

尝试建立一个全新的ASP.NET网站项目等特技，在其上复制粘贴源文本（在同一台机器上 - 没有帮助）或使用相同的VS2005安装在第二台机器上移动项目（它有帮助，项目正常工作）我几乎可以肯定我的代码没有问题，但我的VS / .NET配置。我绝望地不知道如何治愈它，因为互联网上没有描述类似问题的痕迹，除此之外。

答案 7 :(得分：0)

重新安装.Net Framework 2.0。

那应该解决它。之后，gacutil（从v2.0开始）将显示1 mscorlib而不是0。
