Question

I want to upload the image using the .NET webservices and that will be called from iphone image.

the format of text that iphone is sending to me is like this.

http://d8768157.u118.c6.ixwebhosting.com/iphoneimg/image.txt

In which datatype i must convert this data and then save that in image format.

If you have any other method then please tell me.

I have tried converting this data in the byte[] but it is giving me error. here is my code. For what i have tried. please help me out.

[WebMethod]
    public XmlDocument testuploadimage(string image)
    {
        XmlDocument login = new XmlDocument();
        XmlDeclaration dec = login.CreateXmlDeclaration("1.0", null, null);
        login.AppendChild(dec);
        XmlElement root = login.CreateElement("CreateUser");
        login.AppendChild(root);
        try
        {

            string actFolder = Server.MapPath("~/iphoneimg/");
            string imgname = DateTime.UtcNow.ToString().Replace(" ", "").Replace("AM", "").Replace("PM", "").Replace("/", "").Replace("-", "").Replace(":", "") + ".png";

            Bitmap map;

            using (MemoryStream stream = new MemoryStream(Convert.FromBase64String(image)))
            using (FileStream fs = File.Create(actFolder + imgname))
            {
                map = (Bitmap)Image.FromStream(stream);
                map.Save(fs, System.Drawing.Imaging.ImageFormat.Gif);
            }

            XmlElement root1 = login.CreateElement("uploaded");
            root1.InnerText = "true";
            root.AppendChild(root1);
            XmlElement root2 = login.CreateElement("path");
            root2.InnerText = "http://d8768157.u118.c6.ixwebhosting.com/iphoneimg/" + imgname;
            root.AppendChild(root2);

            return login;
        }
        catch (Exception ex)
        {
            throw ex;
        }

[WebMethod]
public XmlDocument testuploadimage(string image)
{
    XmlDocument login = new XmlDocument();
    XmlDeclaration dec = login.CreateXmlDeclaration("1.0", null, null);
    login.AppendChild(dec);
    XmlElement root = login.CreateElement("CreateUser");
    login.AppendChild(root);
    try
    {

        string actFolder = Server.MapPath("~/iphoneimg/");
        string imgname = DateTime.UtcNow.ToString().Replace(" ", "").Replace("AM", "").Replace("PM", "").Replace("/", "").Replace("-", "").Replace(":", "") + ".Png";

        byte[] imageBytes = Convert.FromBase64String(image.Replace(" ","+"));
        MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);

        // Convert byte[] to Image
        ms.Write(imageBytes, 0, imageBytes.Length);
        System.Drawing.Image image2 = System.Drawing.Image.FromStream(ms, true);
        image2.Save(actFolder + imgname);


        XmlElement root1 = login.CreateElement("uploaded");
        root1.InnerText = "true";
        root.AppendChild(root1);
        XmlElement root2 = login.CreateElement("path");
        root2.InnerText = "http://d8768157.u118.c6.ixwebhosting.com/iphoneimg/" + imgname;
        root.AppendChild(root2);

        return login;
    }
    catch (Exception ex)
    {
        throw ex;
    }

}

I got the answers…

thanks to all….
