I need to get file url after upload the file to amazons3 server. Here is my upload code. How to return amazons3 path ?

public static bool UploadToS3(string bucketName, string bucketFilePath, Byte[] localPath)
    {
        var client = Amazon.AWSClientFactory.CreateAmazonS3Client(Config.EmailServer.AwsAccessKey, Config.EmailServer.AwsSecretKey, Amazon.RegionEndpoint.EUWest1);

        PutObjectRequest request = new PutObjectRequest()
        {
            BucketName = bucketName,
            Key = bucketFilePath,
            InputStream = new MemoryStream(localPath),
            AutoCloseStream = true,
            CannedACL = S3CannedACL.PublicRead,
            StorageClass = S3StorageClass.ReducedRedundancy                
        };

        PutObjectResponse response = client.PutObject(request);
        return true;
    }

Simply you can generate download expiry link after upload completed.

example:

var expiryUrlRequest = new GetPreSignedUrlRequest()
                           .WithBucketName(BucketName)
                           .WithKey(Key)
                           .WithExpires(DateTime.Now.AddDays(10));

string url = _amazonS3Client.GetPreSignedURL(expiryUrlRequest);
