C# upload local image to Chevereto API v1 ezphotoshare.com

Question

I am unsuccessfully trying to programmatically upload an image to ezphotoshare.com with C#. They are using Chevereto v1 as their base. Every time I attempt to upload I get "The remote server returned an error: (400) Bad Request.". Here are some of things I've tried:

int limit = 32766;
        StringBuilder sb = new StringBuilder();
        int loops = img.Length / limit;
        for (int i = 0; i <= loops; i++)
        {
            if (i < loops)
            {
                sb.Append(Uri.EscapeDataString(img.Substring(limit * i, limit)));
            }
            else
            {
                sb.Append(Uri.EscapeDataString(img.Substring(limit * i)));
            }
        }
        string url = "http://ezphotoshare.com/api/1/upload/?key=######&source=" + sb +
                     "&format=json";
        var uploadImageRequest = (HttpWebRequest)WebRequest.Create(url);
        uploadImageRequest.Method = "POST";

        var response = (HttpWebResponse)uploadImageRequest.GetResponse();

Here is something else I tried:

string img = ImageReturn(@"C:\avatar63New3.jpg");
using (WebClient client = new WebClient())
        {
            byte[] response3 = client.UploadValues("http://ezphotoshare.com/api/1/", new NameValueCollection()
            {
                { "key", "######" },{"format","txt"},{"action","upload"},{"source",img}
            });
            Console.WriteLine(XDocument.Load(new MemoryStream(response3)));
        }

private static string ImageReturn(string imageLocation)
    {
        using (Image image = Image.FromFile(imageLocation))
        {
            using (MemoryStream m = new MemoryStream())
            {
                //image.Save(m, image.RawFormat);
                image.Save(m, ImageFormat.Jpeg);
                byte[] imageBytes = m.ToArray();

                string base64String = Convert.ToBase64String(imageBytes);
                return base64String;
            }
        }
    }

I've tried many different variations of the code above with no luck. Pointing me in the right direction would be greatly appreciated. Thanks.

Thanks, but this project is using the 4.5 framework and I do not seem to be able to use the new way without changing the framework. Any other suggestions? – Roro May 09 '17 at 19:46
I understand your issue, do you already tested the api, using postman for example? If yes, was succeeded? – Vinicius Maciel May 09 '17 at 20:01
