Performing an Asynchronous Download

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference

You can call ObsClient.BeginGetObject and ObsClient.EndGetObject to download an object in asynchronous mode. Sample code is as follows:

// Create an instance of ObsClient.
ObsClient client = new ObsClient("*** Provide your Access Key ***", "*** Provide your Secret Key ***", "https://your-endpoint");
// Download an object in asynchronous mode.
try
{
    GetObjectRequest request = new GetObjectRequest()
    {
        BucketName = "bucketname",
        ObjectKey = "objectname",
    };
    client.BeginGetObject(request, delegate(IAsyncResult ar){
        try
        {
            using (GetObjectResponse response = client.EndGetObject(ar))
            {
                string dest = "savepath";
                if (!File.Exists(dest))
                {
                    // Write the data streams into the file.
                    response.WriteResponseStreamToFile(dest);
                }
                Console.WriteLine("Get object response: {0}", response.StatusCode);
             }
        }
        catch (ObsException ex)
        {
            Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
            Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
        }
    }, null);
    
}
catch (ObsException ex)
{
   Console.WriteLine("Message: {0}", ex.Message);
}
