I'm trying to save a file to the server and then load into a reader for it to be downloaded. However, I am getting a FileNotFoundExeption. I save to the exact same path, manually open the directory and can see the file there. However, reading it results in the exception. This is my first time trying his - am I doing something wrong?
try
{
using (StreamReader reader = new
StreamReader(HttpContext.Current.Server.MapPath(#"~/Downloads/data.text")))
{
// do something
}
}
catch (Exception)
{
}
Double-check the file name! In one of your comments you used the file name data.txt and not the name data.text. I suppose it's just a typo in your code.

I want to compile a code with codedom which should connect to my ftp server.
But I cant type in the credentials because of the ""...
Look here :
Temp.AppendLine(#"request.Credentials = new NetworkCredential("userid","userpassword");");
If I type " in the code, it automatic ends the content of the brackets...
Help?
You may need to escape the content by using double quotes, like this:
Temp.AppendLine(#"request.Credentials = new NetworkCredential(""userid"",""userpassword"");");
Temp.AppendLine(#"request.Credentials = new NetworkCredential(""userid"",""userpassword"");");
Escape the " with ""

After downloading from my FTP Server, and trying to overwrite that file with an updated one, I get an exception saying: "UnauthorizedAccessException was handled", that, Access to the Path 'C:\My Program\My Program\bin\Debug\App_Data' is denied.
This is what my code looks like:
private void downloadFile () {
WebClient wc = new WebClient();
wc.Proxy = null;
wc.Credentials = new NetworkCredential("user", "pass");
byte[] fileData = wc.DownloadData("ftp://user:pass#mysite.tk/updates/App_Data/log.txt");
File.WriteAllBytes(Application.StartupPath + "\\App_Data", fileData);
}
Am I just missing something to set into the WebClient instance that can allow the 'File.WriteAllBytes' to write the file I'm downloading from my FTP Server to my local machine?
If you think about it, this obviously has nothing to do with WebClient. If you took the same sequence of bytes that you got from WebClient, and tried to write it to the same file, you'd get the same result.
In fact, you'd probably get the same result if you tried to write a single byte, and maybe zero bytes.
Like the exception says,
Access to the Path 'C:\My Program\My Program\bin\Debug\App_Data' is denied
Does the App_Data folder even exist?

I want to use the DownloadFile function of webclient but I used breakpoint to see which line O got error. It just go to catch block when DownloadFile.
try
{
string myStringWebSource = this.curFtpIp + FtpCuPath + "/" + FtpdfName + "/" + this.lbl.Text;
WebClient client = new WebClient();
client.Credentials = new NetworkCredential(this.FtpUserID, this.FtpPassword);
client.DownloadFile(myStringWebSource, SaveFile);
}
catch (Exception ex)
{ MessageBox.Show(ex.Message); }
finally { }
I have solved my own question. I found that I set the wrong second parameter. I just use "SaveFile" which is save path but it should be a file name. So, I just modified the SaveFile and it can work.

The code:
'Files' is a List<string> and _indx is an int.
label22.Text = files[_indx];
For example in 'files' in index[0] I have this string:
D:\New folder (45)\converted.avi_Automatic\Lightning 0 Length 2 [91 - 93]\000091.bmp
But instead in label22.Text I want it to show me only '000091.bmp' without the rest of the directory path.
How can I do it ?
Use Path.GetFileName:
label22.Text = Path.GetFileName(files[_indx]);
I believe you are looking for Path.GetFileName():
label22.Text = Path.GetFileName(files[_indx]);
Path.GetFileName(fileName) returns the file name without the directory.
taken from http://msdn.microsoft.com/en-us/library/system.io.path.getfilename(v=vs.100).aspx
The simplest way is
Path.GetFileName(files[_indx]);

I was trying to convert the following c# code to vb.net.
I see the problem is my lack of familiarity with the syntax of the parameters of OrderByDescending() What is the proper VB.Net equivalent of the C# line?
//C# code
SelectedFolder.Search("ALL", true).OrderByDescending(_ => _.Date).ToList();
//VB.Net part which doesn't work
For Each msg In SelectedFolder.Search("ALL", True).OrderByDescending(Function(_).[Date]).ToList()
After removing the underscore before [Date] the error became,
Error 1 Identifier expected.
The _ character is a line continuation in VB. Try changing the variable name to something more common, like x
For Each msg In SelectedFolder.Search("ALL", True).OrderByDescending(Function(x) x.[Date]).ToList()
