convert java to c#

[buxtonicer1]

Is there a way to convert a java class to c# .
I'm thinking some application, website or tool to help.

Anyone here done it ?

There probably is but I doubt if it does it 100% correctly. Try a simple search to find out:

Ya thats what I've been doing.

The code below is what I'm trying to convert or find c# that has similar functionality.

import java.io.*;
import java.net.*;
import java.util.Date;

/**
* This simple program uses the URL class and its openStream() method to
* download the contents of a URL and copy them to a file or to the console.
**/
public class

url_timer {

public static void main(String[] args) {
long prenow = 0;
long postnow = 0;
String urlname = "<URL>";
InputStream in = null;

try {
FileInputStream fin = new FileInputStream("d:\\temp\\urls.txt"); //Can be done in c#

// now turn the FileInputStream into a DataInputStream
try {
DataInputStream myInput = new DataInputStream(fin);

try {
while ((urlname = myInput.readLine()) != null) {

Its this functionality below that I'm trying to replicate but having difficulty in doing. The code takes a url and works out the size of the file it links to by counting the number of bytes it has. As you can see there is a time stamp before and after the process --- this is used to give an estimation of how long a file would take to download.
Does anyone know of something similar that I can use in c#
a similar url class perhaps ...... Cheers for your help


URL url = new URL(urlname);
URLConnection uc = url.openConnection();
uc.setDefaultUseCaches(false);
uc.setUseCaches(false);
uc.setRequestProperty("Cache-Control",
"max-age=0,no-cache");
uc.setRequestProperty("Pragma", "no-cache");
uc.setRequestProperty("Cache-Control", "no-cache");
in = uc.getInputStream();
byte[] buffer = new byte[4096];
int bytes_read;

prenow = System.currentTimeMillis();
System.out.print(prenow + "\n");


while ((bytes_read = in.read(buffer)) != -1)

postnow = System.currentTimeMillis();
System.out.print(postnow + "\n");
System.out.print(postnow - prenow + "\n");
// System.out.println(thisLine);
} // while loop ends here
} catch (Exception e) {
System.out.println("Error: " + e);
}
} // end try
catch (Exception e) {
System.out.println("Error: " + e);
}

} // end try

catch (Exception e) {
System.out.println("Error: " + e);
}
}
}

This is what i use... I converted it to C# but it need some castings. In vb.NET that i originally have it, it run without any problem.

using System.Net;
using System.IO;

          HttpWebRequest wbrqLogin; 
          HttpWebResponse wbrsLogin;
          String strTemp;
          StreamReader srLogin;

          wbrqLogin = WebRequest.Create("[URL unfurl="true"]http://www.tek-tips.com");[/URL]
          wbrqLogin.Method = "GET";

          wbrsLogin = wbrqLogin.GetResponse();
          srLogin = new StreamReader(wbrsLogin.GetResponseStream());
          strTemp = srLogin.ReadToEnd.Trim;
          srLogin.Close();

          this.textBox1.Text = strTemp;

Getting the following error with this code ...

private void btnDownload_Click(object sender, System.EventArgs e)
{
//****************************************************
Uri uri = new Uri("

http://cslibrary.stanford.edu/107/UnixProgrammingTools.pdf#search="unix filetype:pdf"");

System.Net.WebRequest wr = System.Net.HttpWebRequest.Create(uri);
System.IO.Stream stream = wr.GetResponse().GetResponseStream();
int b;
int counter=0;
string strResult = string.Empty;
while ((b=stream.ReadByte())!=-1)
{
strResult += System.Text.UTF7Encoding.UTF7.GetString(new byte[] {
(byte)b },0,1);
counter++;
Response.Write(counter);
}
stream.Close();
//****************************************************
}

Not looking good for this approach since got no replies - bit of a worry

 

[TipGiver]

Did you try my code?

Also, i think that you are in the wrong forum!

 

[buxtonicer1]

What forum should I be in then , ya tried code similar to yours but that error will still occur ?

 

[TipGiver]

You want to 'run' a site and save its source code to a text file (maybe html), or just show the result in a console window or in a textbox. Is it supposed to be done by a web site, or it is a windows application ?

 

[buxtonicer1]

Its a webform that makes a request to a website ....

But I need to focus on fixing the following

[WebException: The underlying connection was closed: The remote name could not be resolved.]
System.Net.HttpWebRequest.CheckFinalStatus()
System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
System.Net.HttpWebRequest.GetResponse()
DownLoadTime.WebForm1.btnDownload_Click(Object sender, EventArgs e) in c:\inetpub\

http://wwwroot\downloadtime\webform1.aspx.cs:109

System.Web.UI.WebControls.Button.OnClick(EventArgs e)
System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)
System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
System.Web.UI.Page.ProcessRequestMain()


Not much on google though. So I think I'm in the right forum as its an asp.net /c# issue
