获取元数据活动是您想要的. https://docs.microsoft. com/en-us/azure/data-factory/control-flow-get-metadata-activity

Get metadata activity is what you want. https://docs.microsoft.com/en-us/azure/data-factory/control-flow-get-metadata-activity

1. 请使用childItems获取所有文件.然后使用foreach迭代childItems

1. Please use childItems to get all the files. And then use a foreach to iterate the childItems

在每个活动的内，您可能要检查每个项目是否是一个文件.您可以使用if活动和以下表达式.

Inside the for each activity, you may want to check if each item is a file. You could use if activity and the following expression.

然后在如果为true"活动中，假设您要复制数据，则可以使用@item().name来获取每个文件名.

Then in the "If true" activity, assume you want to copy data, you could use @item().name to get each of your file name.
