binary string to image?

foreach (XmlNode customer in customerlist.SelectNodes("Customer"))
                {
                    first_name = customer.SelectSingleNode("CustomerFirstName").InnerXml;
                    last_name = customer.SelectSingleNode("CustomerLastName").InnerXml;
                    total_orders = customer.SelectSingleNode("CustomerOrders").InnerXml;
                    user_image = Convert.FromBase64String(customer.SelectSingleNode("CustomerPhoto").InnerXml);

                    output.Text += "\n  <tr>";
                    output.Text += "\n   <td><img src=\"photo.png\"></td>";
                    output.Text += "\n   <td>" + first_name + "</td>";
                    output.Text += "\n   <td>" + last_name + "</td>";
                    output.Text += "\n   <td>" + total_orders + "</td>";
                 }

how do i use the variable user_image (of type byte[]) to display the user image ??

Re: binary string to image?

Can you try this function to convert to byte array

// C# to convert a string to a byte array.
public static byte[] StrToByteArray(string str)
{
System.Text.UTF8Encoding encoding=new System.Text.UTF8Encoding();
return encoding.GetBytes(str);
}
and pass the byte array for generating the image
public static Image CreateImage(byte[] imageData)
{
Image image;
using (MemoryStream inStream = new MemoryStream())
{
inStream.Write(imageData, 0, imageData.Length);

image = Bitmap.FromStream(inStream);
}

return image;
}

Hope it helps,thanks.

Re: binary string to image?

the public static image gives me this error

Error 1 'Image' is an ambiguous reference between 'System.Web.UI.WebControls.Image' and 'System.Drawing.Image'

edit:

i got it to work .. my code had both 'System.Web.UI.WebControls.Image' and 'System.Drawing.Image'

.. any way now that it's working..

im getting back an image type how do i use it as an html image src?

Re: binary string to image?

try the below code for generating the image from byte array and assign the generated image to the control.

private void byteArrayToImage(byte[] byteArrayIn)
    {
        System.Drawing.Image newImage;
 
        string strFileName = GetTempFolderName() + "yourfilename.gif";
        if (byteArrayIn != null)
        {
            using (MemoryStream stream = new MemoryStream(byteArrayIn))
            {
                newImage = System.Drawing.Image.FromStream(stream);
 
                newImage.Save(strFileName);
 
                img.Attributes.Add("src", strFileName);
            }
 
            lblMessage.Text = "The image conversion was successful.";
        }
        else
        {
            Response.Write("No image data found!");
        }
    }

hope it helps.thanks,

Re: binary string to image?

what's that ?

GetTempFolderName()

Re: binary string to image?

that is the function tat returns the path of the tempfoldername. Just return a string showing the path of the folder where you want to save the image.
