我遗漏了什么?几个问题
ExportClientConfigurationItems属性的类型应为ExportClientSettingsCollection not IEnumerable。
在您的配置文件中,路径是大写字母,它应该是小写字母Path=\\Example\Path,因为您已经用小写的ConfigurationProperty修饰了属性。
解决了这两个问题,它就起作用了。作为这个答案的补充,您可以通过为.NET配置框架创建一个私有getter,然后从遵循接口契约的公共getter返回IEnumerable,从而使您的接口保持在tact IExportClientConfiguration中。
