从您的描述和随附的代码来看，ReportData 类中没有任何属性.如果我认为正确，该类应该生成要在报告中显示的 IEnumerable.

From your description and accompanying code, there are no properties in the ReportData class. If I reckon well, that class is supposed to be generating the IEnumerable you want to display on the report.

如果是这种情况，您必须在向导中选择 Employee 类作为数据源.这将允许您在报告中显示数据.

If that's the case, you'll have to select the Employee class as the DataSource in the wizard. This will allow you to display the data on your report.

我将处理一个快速项目，稍后将其添加到此答案中.

I'll work on a quick project and add it to this answer in a moment.
