推荐答案
您上传您返回的文件资源。
文件资源包含一个称为字段 alternatelink
File resource contains a field called alternatelink
alternateLink结果字符串结果的链接在相关谷歌打开文件
编辑器或浏览器。
alternateLink
string
A link for opening the file in a relevant Google editor or viewer.
您可以与其他用户共享此链接，他们将能够在驱动中打开该文件，他们也应该能够从驱动器下载。
You can share this link with other users they will be able to open the file in drive they should also be able to download it from drive.
有一个名为另一个领域 downloadUrl 这可能让他们下载它，但我还没有测试，一个个人。如果我没有记错 downloadUrl 为空有时候，所以我没有使用它。
There is another field called downloadUrl which might let them download it but I haven't tested that one personal. If I remember correctly downloadUrl was null sometimes so I didn't use it.
Console.WriteLine("Alternate link: " + item.AlternateLink);
