Uploading an image to Winstagram

gistfile1.cs

WebServiceClient client = null;

public static void Main(string[] args)
{
    client = new WebServiceClient("YOUR_API_KEY");

    // login with user's credentials
    client.AuthenticateCompleted += new RequestCompletedEventHandler(client_AuthenticateCompleted);
    client.Authenticate("YOUR_USERNAME", "YOUR_PASSWORD");
}

private static void client_AuthenticateCompleted(object sender, RequestCompletedEventArgs e)
{
    // authentication succeeeded, store this password
    string hashedPassword = client.HashPassword("YOUR_PASSWORD");

    // upload the image
    client.UploadPictureCompleted += new RequestCompletedEventHandler(client_UploadPictureCompleted);
    client.UploadPicture(YOUR_IMAGE_STREAM);
}

private static void client_UploadPictureCompleted(object sender, RequestCompletedEventArgs e)
{
    // extract response
    PictureURL result = e.Data as PictureURL;

    // create new picture
    Picture data = new Picture();

    data.Caption = "This is my caption.";
    data.Latitude = 100.000;
    data.Longitude = -100.000;
    data.URL = result.URL;

    // upload the picture object
    client.CreatePictureCompleted += new RequestCompletedEventHandler(client_CreatePictureCompleted);
    client.CreatePicture(data);
}

private static void client_CreatePictureCompleted(object sender, RequestCompletedEventArgs e)
{
    // your picture was uploaded successfully!
}

Code is in place to throw an exception in the event that authentication, upload, or creation methods fail. These should be handled appropriately by the UI.
