如何使用GoogleDrive REST API将大文件（大于1 GB）上传到Google云端硬盘

Question

I am tying to upload large files(1 GB+) to Google Drive using GoogleDrive API. My code works fine with smaller files. But when it comes to larger files error occurs.

Error occurs in the code part where the the file is converted into byte[].

byte[] data = System.IO.File.ReadAllBytes(filepath); 

Out of memory exception is thrown here.

Probably you followed developers.google suggestions and you are doing this

 byte[] byteArray = System.IO.File.ReadAllBytes(filename); MemoryStream stream = new MemoryStream(byteArray); try { FilesResource.InsertMediaUpload request = service.Files.Insert(body, stream, mimeType); request.Upload(); 

I have no idea why the suggest to put the whole file in a byte array and then create a MemoryStream on it. I think that a better way is this:

using(var stream = new System.IO.FileStream(filename,
                                            System.IO.FileMode.Open, 
                                            System.IO.FileAccess.Read))
{
    try 
    {
       FilesResource.InsertMediaUpload request = service.Files.Insert(body, stream, mimeType);
       request.Upload();
       .
       .
       .
}
