类似于这个问题Getting public URL to file in Google Drive using .NET API。

使用 Google.APIs.Drive.v2 API 我可以列出文件DriveService.Files.List()。这将返回一个文件集合。

这些项目有一个属性exportLinks，但是该属性对于我的所有文件都是空的。

请指教。谢谢。

注意：文件所在的文件夹使用 Visible with Link 共享。

并非所有文件格式都支持 exportLinks，png 就是其中之一。要了解所有可能的导入/导出组合，请请求关于提要并检查importFormats和exportFormats字段：

如果您在 Google 文档中遇到缺少 exportLinks 的情况，请仔细检查您的权限范围。
