Performing an Asynchronous Upload

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.BeginPutObject and ObsClient.EndPutObject to upload 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");
// Upload a file in asynchronous mode.
try
{
    PutObjectRequest request = new PutObjectRequest()
    {
        BucketName = "bucketname",
        ObjectKey = "objectname",
        FilePath = "localfile",// Path of the local file to be uploaded. The file name must be specified.
    };
    client.BeginPutObject(request, delegate(IAsyncResult ar){
        try
        {
            PutObjectResponse response = client.EndPutObject(ar);
            Console.WriteLine("put 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);
}
