C#的code
byte[] body = null;
string fileName = "1.txt";
string filePath = @"c:\1.txt";
//讀取檔案
using( FileStream inFile = new FileStream( filePath, FileMode.Open ) )
{
byte[] inBytes = new byte[ inFile.Length ];
inFile.Read( inBytes, 0, inBytes.Length );
body = inBytes;
}
//設定上傳Url
string url =@"http://127.0.0.1/upload.aspx";
HttpWebRequest req = ( WebRequest.Create( url ) as HttpWebRequest );
string boundary = guid.Replace( "-", "" );
req.ContentType = "multipart/form-data; boundary=" + boundary;
req.Method = "POST";
MemoryStream postData = new MemoryStream();
string newLine = "\r\n";

"Attatch",
fileName ,
newLine
);
sw.Write( "Content-Type: application/octet-stream" + newLine + newLine );

//讀取檔案至postData
