将图像从WP7发送到WCF并转换为位图

Question

I'm trying to send a picture from my Windows Phone to a WCF service, which needs a System.Drawing.Bitmap. I however, am not able to take the BitmapImage from my phone, and get a Bitmap on the WCF service. I'm doing this in C#.

I've tried making the BitmapImage into a byte[], sending it over the WCF, and converting it back to a BitmapImage, and then converting that to a Bitmap. I can get the size of the BitmapImage, but the data in the image is empty. Any clues to what could go wrong?

How do I do this?

Answer 1

The problem probably is with the maxReceivedMessageSize . You said that you can get the size of the BitmapImage but is it the correct size? If not then add the following line in your WCF's web.config:

<bindings>
  <wsHttpBinding>
    <binding name="wsHttp"
                 maxReceivedMessageSize ="50000000"
                 messageEncoding="Mtom"
                 maxBufferPoolSize="50000000" >
      <readerQuotas maxDepth="32"
         maxStringContentLength="2147483647"
         maxArrayLength="2147483647"
         maxBytesPerRead="8192"
         maxNameTableCharCount="2147483647" />
    </binding>
  </wsHttpBinding>
</bindings>

Now try again, it should work now.
