任何人都有共享的方式将docx,xlsx,pptx转换为程序化的谷歌格式。我正在通过Google Drive API上传并使用c#与用户分享。每当有人编辑文件时,每次创建一个重复的文档。
我想在上传时转换文件。所以我可以将转换后的文件分享给每个人。
我正在使用Google Drive v3 api。
下载代码:
private static System.IO.MemoryStream DownloadFile(DriveService service, string fileID)
{
var request = service.Files.Get(fileID);
var stream = new System.IO.MemoryStream();
// Add a handler which will be notified on progress changes.
// It will notify on each chunk download and when the
// download is completed or failed.
request.MediaDownloader.ProgressChanged += (Google.Apis.Download.IDownloadProgress progress) =>
{
switch (progress.Status)
{
case Google.Apis.Download.DownloadStatus.Downloading:
{
Console.WriteLine(progress.BytesDownloaded);
break;
}
case Google.Apis.Download.DownloadStatus.Completed:
{
Console.WriteLine("Download complete.");
//SaveStream(stream, saveTo);
break;
}
case Google.Apis.Download.DownloadStatus.Failed:
{
Console.WriteLine("Download failed.");
break;
}
}
};
request.Download(stream);
return stream;
}
private static void SaveStream(System.IO.MemoryStream stream, string saveTo)
{
using (System.IO.FileStream file = new System.IO.FileStream(saveTo, System.IO.FileMode.Create, System.IO.FileAccess.Write))
{
stream.WriteTo(file);
}
}

这是让你开始我的朋友的事情。查看Basic uploads和Importing to Google Docs types,因为它会向您展示如何上传和转换某些文件类型为Google格式。
var fileMetadata = new File()
{
Name = "My Report",
MimeType = "application/vnd.google-apps.spreadsheet"
};
FilesResource.CreateMediaUpload request;
using (var stream = new System.IO.FileStream("files/report.csv",
System.IO.FileMode.Open))
{
request = driveService.Files.Create(
fileMetadata, stream, "text/csv");
request.Fields = "id";
request.Upload();
}
var file = request.ResponseBody;
Console.WriteLine("File ID: " + file.Id);
