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.

    The error you receive is explicit enough. What are you asking us exactly? – Frédéric Hamidi Oct 07 '15 at 13:05

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();
       .
       .
       .

I use next code and works fine whith a file > 1gb

using (var stream = new System.IO.FileStream(_uploadFile, System.IO.FileMode.Open, System.IO.FileAccess.Read))       
{              
    try
    {
        FilesResource.CreateMediaUpload request = service.Files.Create(body, stream, GetMimeType(_uploadFile));
        request.SupportsTeamDrives = true;
        request.Upload();
        var file = request.ResponseBody;
        string fileId = file.Id;
    
        request = null;
    }
    catch (Exception ex)
    {
               
    }

    stream.Dispose();
    body = null;
