I don’t know what is going on.  
And here is my c# code  
using System;  
using System.Collections.Generic;  
using System.Text;  
using System.Web;  
using [System.Net](http://System.Net);  
using [System.IO](http://System.IO);

namespace ConsoleApplication13  
{  
class Program  
{  
static void Main(string[] args)  
{  
Program test = new Program();  
test.firstmethod();

```
    }
    private void firstmethod()
    {
        string url = "http://localhost:3002/filelink/upload2";
        string[] files = { "c:\\test.txt" };
        string logpath = null;
        UploadFilesToRemoteUrl(url, files, logpath);
    }
    private void UploadFilesToRemoteUrl(string url, string[] files,

```

string logpath)  
{

```
        long length = 0;
        string boundary = "----------------------------" +

```

DateTime.Now.Ticks.ToString(“x”);

```
        HttpWebRequest httpWebRequest2 =

```

(HttpWebRequest)WebRequest.Create(url);  
httpWebRequest2.ContentType = “multipart/form-data;  
boundary=” + boundary;  
httpWebRequest2.Method = “POST”;  
httpWebRequest2.KeepAlive = true;

```
        httpWebRequest2.Credentials =
        System.Net.CredentialCache.DefaultCredentials;

        Stream memStream = new System.IO.MemoryStream();

        byte[] boundarybytes2 =

```

System.Text.Encoding.ASCII.GetBytes(“–” + boundary + “\r\n”);  
byte[] boundarybytes =

        memStream.Write(boundarybytes2,0,boundarybytes2.Length);

        string headerTemplate = "Content-Disposition: form-data;

```
        for(int i=0;i<files.Length;i++)
        {

        string header =

        byte[] headerbytes =

        int bytesRead = 0;

        while ( (bytesRead = fileStream.Read(buffer, 0,

```

buffer.Length)) != 0 )  
{  
memStream.Write(buffer, 0, bytesRead);  
length += bytesRead;  
}

```
        memStream.Write(boundarybytes,0,boundarybytes.Length);
        length += boundarybytes.Length;

        fileStream.Close();
        }

        httpWebRequest2.ContentLength = memStream.Length;

        Stream requestStream = httpWebRequest2.GetRequestStream();

        memStream.Position = 0;
        byte[] tempBuffer = new byte[memStream.Length];
        memStream.Read(tempBuffer,0,tempBuffer.Length);
        memStream.Close();

        requestStream.Close();

        WebResponse webResponse2 = httpWebRequest2.GetResponse();

        Stream stream2 = webResponse2.GetResponseStream();
        StreamReader reader2 = new StreamReader(stream2);

        Console.WriteLine(reader2.ReadToEnd());

        webResponse2.Close();
        httpWebRequest2 = null;
        webResponse2 = null;

        }
}

```

}

Here is My ruby on rails code  
class FilelinkController \< ApplicationController  
require “ftools”  
scaffold :filelink

def index  
redirect\_to :action =\> “list”  
end  
def list  
@filelink = Filelink.find\_all  
end

def uploads  
link = String.new()  
@link = Date.today().strftime(“%d\_%m\_%y”).to\_s()  
@filelink = Filelink.new()  
@filelink[‘patientname’] = @params[‘patientname’]  
@filelink[‘filelink’] = “#{RAILS\_ROOT}/public/file/”+@link+“.txt”  
File.open(@filelink[‘filelink’], “wb”) { |f|  
f.write(@params[‘any\_file’].read) }  
#do |f|  
#f.write(@params[‘any\_file’].read)  
#end  
@filelink.save  
redirect\_to :action =\> “list”  
end  
###The Used Part  
def upload2  
if File.size?(@params[‘any\_file’])\>0  
File.open(“#{RAILS\_ROOT}/public/file/try.txt”, “wb”) do |f|  
f.write(@params[‘any\_file’].read)  
end  
else  
redirect\_to :action =\>“list”  
end  
redirect\_to :action =\>“list”  
end

##### 

end

And here is the form

**Upload file form**
# **Add a patient records**

For more information, i use Aptana as the development platform of ror,  
and i use visual [studio.net](http://studio.net) 2005 as the c# development platform.
