VS2019 16.4.2中.editorconfig C#命名规则不生效求助

我最近在解决方案级别用.editorconfig给两个C#项目定义命名规则，刚把Visual Studio更到最新的16.4.2版本，结果工具提示的警告完全不对劲儿：类名、属性名、枚举名居然提示要小写开头，但我明明配置的是Pascal命名法；私有字段我设的是下划线开头，也收到错误提示。我确认编辑器加载了我的.editorconfig，因为改配置的时候提示会变，但结果就是不符合预期。想问下是不是要额外设置？还是我的配置有问题？

以下是我的.editorconfig相关内容：

问题排查与修正方案 #

我仔细检查了你的配置，发现几个关键问题，这应该就是规则不生效的根源：

1. 符号定义里的拼写错误

你在pubMethods的可访问性配置里多打了一个点：

dotnet_naming_symbols.pubMethods..applicable_accessibilities = public

这个错误会导致该规则完全失效，改成下面这样即可：

dotnet_naming_symbols.pubMethods.applicable_accessibilities = public

2. 规则优先级顺序错误

在.editorconfig中，后定义的规则优先级更高。你把通用的defaultFieldsCamel规则放在了privateFieldsUnderscore之后，导致通用规则覆盖了私有字段的特殊规则。需要把更具体的规则（比如私有字段）放在通用规则的后面。

3. 静态/常量字段的规则配置颠倒

你给staticFieldsPascal和constFieldsPascal指定的样式是c（小驼峰），但规则名称是Pascal，明显和你的预期相反。如果你想让静态/常量字段使用Pascal命名，需要把style = c改成style = P。

额外的Visual Studio设置检查

除了配置文件，还需要确认VS的设置是否正确：

• 打开工具 > 选项 > 文本编辑器 > C# > 代码样式 > 命名，确保启用.editorconfig支持选项已勾选
• 如果之前手动设置过命名规则，建议点击重置为默认值，让.editorconfig的规则优先生效
• 最后重启Visual Studio，确保配置完全加载
