修复:全局元素“配置"已被声明

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?

即使用按钮创建了一个 XSD 以创建方案.我将 app.config 中的样式表更改为 app.xsd 但现在我收到警告:

全局元素配置"已在 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?

我遇到了与您提到的问题类似的问题，我按照这些说明进行操作，一切都很好.首先确保 EnterpriseLibrary.Configuration.xsd 在 %ProgramFiles%Microsoft Visual Studio [version]XmlSchemas 中，然后执行以下操作:

Enterprise Library 将架构安装到 Visual Studio 中，该架构提供 IntelliSense® 以在 Visual Studio XML 编辑器中编辑 Enterprise Library 配置文件.您必须先打开架构，然后才能使用它.

4. 将使用列中的值更改为使用此架构.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?

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]XmlSchemas 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] XmlSchemas, then select EnterpriseLibrary.Configuration.xsd and click Open.

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