WordPress Can not upload an image through wp.uploadFile using c#

Questions:

I’m working on a .net program to communicate with wordperss through xml-rpc.net. I found that if I’m trying to upload an image which is kind of large through “wp.uploadFile”, wordpress will return an error saying ” parse error(-32700), well not formed”. I tried Windows Live Write to write a post. However, if I choose to link the source picture, I got an error saying I can’t upload an image, and uploading images through ftp was suggested.

I found this article:
Image Uploading Fails

I think there may still be some issue in reading large request does not contain break lines, so I build the xml myself, and add a break line (‘\r\n’) every 76 characters according to RFC 822. But the issue is still there, in another word, I can not upload any kinda large images.
my xml file is as follow:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<methodCall>
  <methodName>wp.uploadFile</methodName>
  <params>
    <param>
      <value>

I’ve been working with WordPress XML-RPC for over 3years.
I attached a Upload request sample that working fine as your reference. I hope this could help you.

<?xml version="1.0"?>
    <methodCall><methodName>wp.uploadFile</methodName>
        <params>
            <param>
                <value><string>1</string></value>
            </param>
        <param>
                <value><string>username</string></value>
        </param>
        <param>
                <value><string>password</string></value>
        </param>
