var values = new NameValueCollection

    { "key", ConfigurationSettings.AppSettings["API-Key"].ToString() },
    { "image", Convert.ToBase64String(File.ReadAllBytes(photo.ToString())) }

所以你的代码将改为:

var values = new NameValueCollection 
{ 
    { "key", ConfigurationManager.AppSettings["API-Key"] }, 
    { "image", Convert.ToBase64String(File.ReadAllBytes(photo.ToString())) } 
};

确保添加引用System.Configuration以及usingfor语句System.Configuration.
