Most likely your array is smaller than the number of lines returned until you encounter the string "];"
Set the array size to a proper value or use a List<string> instead.
Your code looks wrong though, you're reading each line twice. This would be better:
while((line = loadme.ReadLine()) != "];")
{
AddToArray(line);
}

use List<string> to replace string[],
you doesn't to set its length, but save it use .Add methods.
if you want to use string[], you should declare its length
greater than the line count of the file. seems you are reading from a file.
Glad to discuss with you and best wishes.

file length varies, how do I get the length of a file in lines, not chars?

then use List<string> if you are use .NET Framework 2.0 or above.
use ArrayList if you are use .NET Framework 1.1
its length add dynamicly. you can use it and no warry on its length.
or you should read more informance from msdn.
Glad to discuss with you and best wishes.

Hi,
File.ReadAllLines() does it all for you.

Hi
Lets think that there is a client and a server. Client wants to send three files with small sizes to the server. Server's ip address and port is static.
- Server starts listening the port and accepts all the connection attempts coming from any ip address.
- Client establishes a connection to the server. After connecting, starts to send the files.
- Server recieves the files and saves them to the hard disk.
- Client disconnects.
- Server keeps listening the port and accepts all the connection attempts coming from any ip address.
Essentially, this is what I am trying to do. I am not a starter in C# but I am not advanced too. I have designed the code but only first file out of three is recieved by server without a problem. Because client or server doesn't wait for transfer to be completed.
At the same time there can be more than one client connected to server, server should be able to recieve all the files.
Thanks in advance.

It's called FTP. Learn it. Live it.

I know I can use FTP. But I should not use FTP because it is not secure. When you listen the network traffic with a sniffer you can easily see the username and password.
This software will be used by people and I don't want people to see the FTP login informations.

Really?? Google results for "Secure FTP[^]"...

I think you are talking about FTPS.
How can I use FTPS client in C# and is there a FTPS server for linux?
Thanks.

I think you're referring to SFTP[^], not FTPS.
|
|
|
|

Actually I am referring to FTPS not SFTP. Because SFTP is doing his job over SSH and I don't want to risk console access. I prefer using FTPS. FTPS is doing his job with using SSL for encryption.

You can buy a library, or write the code yourself.

Man, you're full of good questions today, aren't you?
I'm sure that if you took the time to use GOOGLE, you would find your answer.

When I open a page in the WebBrowser I see appear notice board:Security information
I want programmed to automatically remove this notice I do? I'm using language C #.NET
|
|

|

From inside a web page? You can't and for good reasons. For that purpose you would have to write your own (unsecure) browser.
|
|
|
|
|
Yes, I want to design a program WebBrowser.Toi will have a program like the user to browse the Web, the program will automatically answer the panel notification Security Information usually appears in a page.

That's a HUGE undertaking for a single person. It normally takes entire TEAMS of people a few years to write a browser from scratch. Good luck with that...

public class StatusChangedEventArgs : EventArgs
{
private string EventMsg;
public string EventMessage
{
get
{
return EventMsg;
}
set
{
EventMsg = value;
}
}
public StatusChangedEventArgs(string strEventMsg)
{
EventMsg = strEventMsg;
}
}
public delegate void StatusChangedEventHandler(object sender, StatusChangedEventArgs e);
public static event StatusChangedEventHandler StatusChanged;
Okay, so in the above code, we created a delegate and a custom event.
public static void OnStatusChanged(StatusChangedEventArgs e)
{
StatusChangedEventHandler statusHandler = StatusChanged;
if (statusHandler != null)
{
statusHandler(null, e);
}
}
What does the bold line do? Why do we check for null?
EDIT: The code is from C# Chat: Part 2 - Building the Chat Server (C# Programming Tutorial) • Geekpedia[^] check that out, if the above code doesn't provides what I mean.

Hi,
you make a local copy of StatusChanged, so the same value gets used both in the null-text and the invocation; StatusChanged is public, so it could be changed by another thread at any point in time; removing the last handler from it right after the null-test got executed would cause an exception in statusHandler(null, e);
In summary, without it your code would not be thread-safe.

I'm sorry, but I didn't got it, what do you mean by null-text and the invocation?
I'm converting this code to C++/CLI so I don't know C#, that's why having little problems...

if (statusHandler != null) <--- that looks like a null-test
statusHandler(null, e); <--- according to the comment this is an invocation

Hmmm, you wrote null-text
lol.. Thanks anyways
|
|
|
|

Isn't that just making a copy of the reference?
And therefore no safer than testing/invoking directly on the original reference?
