How to load and render AWS S3 files using Group Docs in .Net(Framework 4.8)


You can use AWSSDK package to load a file from S3 with GetObject method. The code snippet can be found in Load document from Amazon S3 Storage documentation article. Here is the code:

string key = "sample.docx";
Stream stream = DownloadFile(key);

using (Viewer viewer = new Viewer(stream))
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();                

static Stream DownloadFile(string key)
    AmazonS3Client client = new AmazonS3Client();
    string bucketName = "my-bucket";
    GetObjectRequest request = new GetObjectRequest
        Key = key,
        BucketName = bucketName
    using (GetObjectResponse response = client.GetObject(request))
        MemoryStream stream = new MemoryStream();
        stream.Position = 0;
        return stream;

Please let us know if you have any issues with rendering files from S3.

Thank you for your email Vladimir!
