一个JAVA写的程序怎样把它用C#写出来啊?

Question

下面是一个用JAVA写的在ASP页面接收XML数据的程序,请问如何把它用C#写出来啊?非常感谢!
ServletInputStream sin = request.getInputStream();
byte[] buf = new byte[51200];
int index = 0;
while (true) {
   int ch = sin.read();
   if (ch == -1) break;
   buf[index++] = (byte)ch;
   //out.println(ch);
}
byte[] buf2 = new byte[index];
System.arraycopy(buf, 0, buf2, 0, index);
String info = new String(buf2, "GBK");
out.println(info);

Answer 1

Stream   sin   =   Page.Request.InputStream ;
byte[]   buf   =   new   byte[sin.Length];
        int numBytesToRead = (int) sin.Length;
        int numBytesRead = 0;
        while (numBytesToRead > 0) 
        {
            // Read may return anything from 0 to numBytesToRead.
            int n = s.Read(buf, numBytesRead, numBytesToRead);
            // The end of the file is reached.
            if (n==0)
                break;
            numBytesRead += n;
            numBytesToRead -= n;
        }
        s.Close();String   info   =  Encoding.GetEncoding("GBK").GetString( bytes );
out.println(info);

Answer 2

Stream       sin       =       Page.Request.InputStream   ;
byte[]       buf       =       new       byte[sin.Length];
                int   numBytesToRead   =   (int)   sin.Length;
                int   numBytesRead   =   0;
                while   (numBytesToRead   >   0)  
                {
                        //   Read   may   return   anything   from   0   to   numBytesToRead.
                        int   n   =   s.Read(buf,   numBytesRead,   numBytesToRead);
                        //   The   end   of   the   file   is   reached.
                        if   (n==0)
                                break;
                        numBytesRead   +=   n;
                        numBytesToRead   -=   n;
                }
                s.Close();String       info       =     Encoding.GetEncoding( "GBK ").GetString(   buf );
out.println(info);

Stream               sin               =               Page.Request.InputStream       ;

                                int       numBytesRead       =       0;
                                while       (numBytesToRead       >       0)    
                                {
                                                //       Read       may       return       anything       from       0       to       numBytesToRead.
                                                int       n       =       s.Read(buf,       numBytesRead,       numBytesToRead);
                                                //       The       end       of       the       file       is       reached.
                                                if       (n==0)
                                                                break;
                                                numBytesRead       +=       n;

                                }
                                s.Close();String               info               =           Encoding.GetEncoding(   "GBK   ").GetString(       buf   );
Console.WriteLine(info);
