修复:全局元素“配置"已经声明 [英] Fix: The Global element 'configuration' has already been declared

问题描述

我使用了第二种解决方案如何解决可以找不到元素/属性的架构信息?

即使用创建方案的按钮创建了一个 XSD.我将 app.config 中的样式表更改为 app.xsd，但现在收到警告:

全局元素配置"已经在 app.xsd 中声明

即使更改名称也会显示警告.有人对此有解决方案吗?

解决方案

我遇到了与您所指问题类似的问题，我按照这些说明操作，一切正常.首先确保 EnterpriseLibrary.Configuration.xsd 在 %ProgramFiles%\Microsoft Visual Studio [version]\Xml\Schemas\ 中，然后执行以下操作:

企业库将架构安装到 Visual Studio 中，该架构提供用于在 Visual Studio XML 编辑器中编辑企业库配置文件的 IntelliSense®.您必须先开启架构，然后才能使用它.

启用企业库配置架构

1. 在解决方案资源管理器中双击 Visual Studio 中的配置文件.

2. 在 XML 菜单上，单击架构...以打开 XML 架构对话框.

3. 找到名为 EnterpriseLibrary.Configuration.xsd 的架构.这是自动安装的.但是，如果它未显示在列表中，请单击添加并导航到文件夹 %Program Files%\Microsoft Visual Studio [version] \Xml\Schemas，然后选择 EnterpriseLibrary.Configuration.xsd 并单击打开.

4. 将 Use 列中的值更改为 Use this schema.然后点击确定.

I used the second solution of How to resolve "Could not find schema information for the element/attribute <xxx>"?

I.e. created a XSD with the button to create a scheme. I changed the stylesheet in app.config to app.xsd but now I get the warning:

The Global element 'configuration' has already been declared in app.xsd

Even when changing the name the warning is shown. Does anybody have a solution for this?

解决方案

I had a similar problem to the question you are referring to, I followed these instructions and everything was fine. Make sure the EnterpriseLibrary.Configuration.xsd is in %ProgramFiles%\Microsoft Visual Studio [version]\Xml\Schemas\ first of all, then do this:

Enterprise Library installs a schema into Visual Studio that provides IntelliSense® for editing Enterprise Library configuration files in the Visual Studio XML editor. You must turn on the schema before you can use it.

To enable the Enterprise Library configuration schema

1. Open the configuration file in Visual Studio by double-clicking it in Solution Explorer.

2. On the XML menu, click Schemas... to open the XML Schemas dialog.

3. Locate the schema named EnterpriseLibrary.Configuration.xsd. This is installed automatically. However, if it is not shown in the list, click Add and navigate to the folder %Program Files%\Microsoft Visual Studio [version] \Xml\Schemas, then select EnterpriseLibrary.Configuration.xsd and click Open.

4. Change the value in the Use column to Use this schema. Then click OK.
