dotnet xml:

Hi,

I have a web service which stores an uploaded image into SQL server, thus
there are a few things need to do:
1. Convert image to base64Binary.
2. Call web service and embed image as base64Binary in XML string.
3. Web service save image binary into SQL.

Where can i find the samples. Is there any other way to implement it.

Thanks in advance

This should get you going:
Bitmap bmp;
XmlWriter writer;
MemoryStream stream = new MemoryStream();
bmp.Save(stream);
stream.Seek(0, SeekOrigin.Begin);
byte[] bytes = stream.GetBuffer();
writer.WriteBase64(bytes, 0, bytes.Length);

If you define the web service method to take an array of Bytes as a
parameter, it will be automatically converted to/from base64 by the .NET
framework. (Use a SOAP trace tool to see for yourself.)
