What have you tried so far and what's the problem? You are right, from the client side, you can use HttpWebRequest in the image URL and copy the stream to local file one-to-one; or, simpler, you can use WebClient download...

Downloading should be done on the initiative of the user, or with the user consent. A Web application does not have access to local systems. I don't think it will be a problem in your case.

hear is solution of my question

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
            txtBarCodeText.Focus();

        var barcode = new Code39BarCode()
        {
            BarCodeText = "HELRE WORLD",
            BarCodeWeight = BarCodeWeight.Medium,
            Height = 100
        };

        byte[] fileContents = barcode.Generate();

        string filePath = Server.MapPath("~/barcode.gif");
        File.WriteAllBytes(filePath, fileContents);
        string filepath1 = Server.MapPath("~/barcode.gif");
        string fn= Guid.NewGuid()+filepath1.Substring(filepath1.LastIndexOf("."));
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:1231/WebFormsDemo/barcode.gif");
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        System.Drawing.Image img = System.Drawing.Image.FromStream(response.GetResponseStream());
        //imgbar is folder name which is stored the new image

        img.Save(Server.MapPath("imgbar/")+fn);

    }
