是否可以为谷歌驱动器 api v3 C# 中的文件添加自定义元数据？

Question

I have a list of files to be uploaded to Google Drive.

Is it possible to add custom metadata to each file?

Answer 1

Yes, this is possible.

See: https://developers.google.com/drive/api/v3/properties

You can set properties and appProperties on the File object.

"To add properties visible to all apps, use the properties field of files resource. To add properties restricted to your app, use the appProperties field on files resource."

Example (assuming you know how to upload the filestream with contenttype, and only want explanation on the metadata):

var file = new File
{
    Properties = new Dictionary<string, string>
    {
        { "CustomTag", "1234" }
    }
};
service.Files.Create(file, fileStream, contentType).Execute();
