意外字符 ''

Question

从 VS2013 迁移到 VS2017 后，我运行遇到了意外的字符问题。

在 msbuild 12.0 和 VS2013 中一切正常，但是当移动到 15.0 时，我收到数百个：

CS1519 Invalid token '?' in class, struct, or interface member declaration

在 msbuild 命令行中。

在 VS2017 中构建 returns:

CS1056 Unexpected character ''

var businessRuleData = principal.GetBusinessRule(
BusinessRuleEnum.CONTENT_REPOSITORY);

Ch66 发生错误，位于该区域之间 (B。隐藏的字符在写字板中变为 ?。但是，如前所述，相同的代码在 msbuild 12.0 中构建良好。删除所有代码并重新下载 TFS 表格未能解决问题

删除所有无效字符，因为 MSBuild 15.0 和 VS2017 对这些 unicode 字符更加严格。

可以使用以下代码来完成删除文件夹中所有有问题的代码。我使用它是因为所需的更改太大而无法手动完成。
