Visual Studio 为什么VS 2005总是给我“'x'在命名空间'y'中不明确”的错误？

我不确定我更改了什么VS设置，或者是web.config设置还是什么，但是我一直在错误列表中看到这个错误，但是所有的解决方案都构建得很好。

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，这真的很烦人，因为代码中到处都是蓝色的波浪形下划线，在错误列表窗格中过滤掉相关的错误几乎是不可能的。我检查了默认的ASP.NET web.config和machine.config，但似乎没有什么突出的。

  • 编辑：* 以下是发生错误的一些源代码：
'Error #5: whole line is blue underlined'
<%= addEmailToList.ToolTip %>

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

'Error #7: Exception is blue underlined'
Catch ex As Exception

'Error #8: System.EventArgs is blue underlined'

我最近也遇到了同样的错误。下面是我如何修复它的（我希望它对你也有效）：

  • 打开项目属性，转到参考部分。
  • 删除上半部分中对系统的引用。
    我认为它引用了系统两次，但它只显示了一次。因此，模棱两可的引用。

基于gacutil输出的结果（谢谢您这样做;我认为这很有帮助），我会说您需要尝试在.NET框架安装和Visual Studio 2005上运行修复程序。我不确定这是否会修复它，但正如您从gacutil的输出中看到的，您没有针对2.0的任何修复程序。
在VS 2005命令提示符下，我得到：

在VS 2003命令提示符下，我得到：

当请求帮助诊断编译问题时，发布违规的源代码通常会有所帮助：）
这些错误确实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。

我也遇到过这种情况，特别是System.Data.SqlClient。尝试在项目管理器中取消选中命名空间，然后手动将其包含在.vb文件中，就像使用C#一样：
导入系统.数据.SqlClient

出现一个错误（如ArrayList），并将类型替换为全限定名（我不确定，但我猜如下所示：如果错误消失了，那么你真的遇到了一个解决冲突的问题，如果没有，那就是别的问题了。
如果所有的解决方案都构建得“很好”，并且有这些错误，我建议清理你的项目。删除所有编译过的东西（dll，pdb，无论什么），也删除阴影缓存的东西。也许它编译是因为它使用了旧版本的东西。

我知道这听起来很奇怪，但是您是使用“生成”还是“重建”来生成解决方案呢？如果我遇到了类似的有趣问题，对解决方案使用“全部重建”会有所帮助。

昨天我在VS2005ASP.NET网站项目中得到了同样的：突然间，由于之前的任何重大代码更改，名称空间“y”中“x”的加载出现了歧义，所有这些加载都源自非常基本的符号，如EventArgs、Type、DBNull等。
直接原因是mscorlib被重复引用，正如我在VS的类视图中看到的，我相信真正的原因是自动Windows更新，它迫使我在几分钟前重新启动机器。
尝试这样的特技像建立一个全新的ASP.NET网站项目，复制粘贴源文本（在同一台计算机上-没有帮助）或将项目移动到安装了相同VS 2005的第二台计算机上（这很有帮助，项目可以正常工作）我几乎可以肯定我的代码没有问题，但我的VS/.NET配置有问题。我非常不知道如何解决它，因为除了这一次，互联网上没有描述类似麻烦的痕迹。

重新安装.Net Framework 2.0。
之后，gacutil（来自v2.0）将显示1 mscorlib而不是0。
