Encoding missing from reading file

Hello i'm developing a little application that download attachment from unread mails by imap and make a sevarla job on this attachment. Problem is encoding because after i have saved a, for example, txt file, when i load it again letters with accents becomes "?" I dont know why. I tried a several example around on the web (like converting directly the file from ansi to utf-8) with no result. Whe i open a file in windows it works, words are correct.
i have used either ReadAllText that StreamReader in the following example:
string contents = File.ReadAllText(AppDomain.CurrentDomain.BaseDirectory + "\\uid\\" + summary.UniqueId.ToString() + "\\" + fileName, Encoding.UTF8);
using (StreamReader reader = new StreamReader(contents, Encoding.UTF8))
as you can see in the following example if i set directly a string with an accent word, it works, from file no.
Please help me!

After searching around on the web i found a solution, here microsoft msdn
Streamreader and maybe readalltext doesn't support accent letters with UTF-8 Encoding, so changing it in UTF-7, letters are showed correctly.
Thank you for all support!

Listing all the files in root directory

Thanks for your support! I now have working code to scan all folders, subfolders and files. There is just one problem left to solve:
I do not get the files in the initial root directory, only the subfolders. I also need to call FileInfo for these files.
How could this be resolved without modifying the code too much?
private void ScanFolder(String prefix, String path)
{
try
{
string user = System.IO.File.GetAccessControl(path).GetOwner(typeof(System.Security.Principal.NTAccount)).ToString();
DirectoryInfo di = new DirectoryInfo(path);
foreach (var dir in new DirectoryInfo(path).GetDirectories("*", SearchOption.TopDirectoryOnly))
{
listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + dir.Name + " (" + dir.Name.Length.ToString() + ") "); });
foreach (FileInfo fileInfo in dir.GetFiles())
{
listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + fileInfo.Name + " (" + fileInfo.Name.Length.ToString() + ") " + user + " " + fileInfo.FullName + " (" + fileInfo.FullName.Length.ToString() + ")"); });
}
ScanFolder(prefix + "—", dir.FullName);
}
}
catch
{
if (!this.IsDisposed)
{
listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add("Access Denied to : " + path); });
}
}
}
Output:
** The files should be here **
13-9-legacy_vista_win7_64_dd_ccc_whql (37)
Radeon-Software-Adrenalin-18.3.3-MinimalSetup-180319_web (56)
—Bin (3)
——localization (12)
———cs (2)
———da_DK (5)
———de (2)
———el_GR (5)
———es_ES (5)

So far you're only looking for the directories in the root directory.
You also want to enumerate through the files though:
private void ScanFolder(String prefix, String path)
{
try
{
string user = System.IO.File.GetAccessControl(path).GetOwner(typeof(System.Security.Principal.NTAccount)).ToString();
DirectoryInfo di = new DirectoryInfo(path);
// Enumerate through the files here
foreach (FileInfo fileInfo in di.GetFiles())
{
listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + fileInfo.Name + " (" + fileInfo.Name.Length.ToString() + ") " + user + " " + fileInfo.FullName + " (" + fileInfo.FullName.Length.ToString() + ")"); });
}
// ----
// You can also use the DirectoryInfo you created earlier here
foreach (var dir in new di.GetDirectories("*", SearchOption.TopDirectoryOnly))
{
listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + dir.Name + " (" + dir.Name.Length.ToString() + ") "); });
foreach (FileInfo fileInfo in dir.GetFiles())
{
listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + fileInfo.Name + " (" + fileInfo.Name.Length.ToString() + ") " + user + " " + fileInfo.FullName + " (" + fileInfo.FullName.Length.ToString() + ")"); });
}
ScanFolder(prefix + "—", dir.FullName);
}
}
catch
{
if (!this.IsDisposed)
{
listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add("Access Denied to : " + path); });
}
}
}

Automatically create folders if does not exists in C#

So, I am trying to create a file at a specific path but the code I have doesn't allows me to create folders.
This is the code I have:
public void LogFiles()
{
string data = string.Format("LogCarga-{0:yyyy-MM-dd_hh-mm-ss}.txt", DateTime.Now);
for (int linhas = 0; linhas < dataGridView1.Rows.Count; linhas++)
{
if (dataGridView1.Rows[linhas].Cells[8].Value.ToString().Trim() != "M")
{
var pathWithEnv = #"%USERPROFILE%\AppData\Local\Cargas - Amostras\_logs\";
var filePath = Environment.ExpandEnvironmentVariables(pathWithEnv);
using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate))
{
using (StreamWriter writer = File.AppendText(filePath + data))
{
string carga = dataGridView1.Rows[linhas].Cells[0].Value.ToString();
string referencia = dataGridView1.Rows[linhas].Cells[1].Value.ToString();
string quantidade = dataGridView1.Rows[linhas].Cells[2].Value.ToString();
string dataemissao = dataGridView1.Rows[linhas].Cells[3].Value.ToString();
string linha = dataGridView1.Rows[linhas].Cells[4].Value.ToString();
string marca = dataGridView1.Rows[linhas].Cells[5].Value.ToString().Trim();
string descricaoweb = dataGridView1.Rows[linhas].Cells[6].Value.ToString().Trim();
string codprod = dataGridView1.Rows[linhas].Cells[7].Value.ToString().Trim();
string tipoemb = dataGridView1.Rows[linhas].Cells[8].Value.ToString().Trim();
string nomepc = System.Environment.MachineName;
writer.WriteLine(carga + ", " + referencia + ", " + quantidade + ", " + dataemissao + ", " + linha + ", " + marca + ", " + descricaoweb + ", " + codprod + ", "
+ tipoemb + ", " + nomepc);
}
}
}
}
}
This %USERPROFILE%\AppData\Local\ in the universal path and I want to automatically create the \Cargas - Amostras\_logs\.
Do you have any idea how to do it?

The simpelest solution is replace
using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate))
with
System.IO.Directory.CreateDirectory(filePath)
That will create the directory if it does not exist or do nothing if it does.

You need to create two checks, for your first folder and then second directory.
var pathWithEnv = #"%USERPROFILE%\AppData\Local\Cargas - Amostras\";
if (System.IO.Directory.Exists(pathWithEnv))
{
pathWithEnv = System.IO.Path.Combine(pathWithEnv, #"_logs\");
if (System.IO.Directory.Exists(pathWithEnv))
{
//Do what you want to do, both directories are found.
}
else
{
System.IO.Directory.CreateDirectory(pathWithEnv);
//Do what you want to do, both directories are available.
}
}
else
{
System.IO.Directory.CreateDirectory(pathWithEnv);
pathWithEnv = System.IO.Path.Combine(pathWithEnv, #"_logs\");
if (System.IO.Directory.Exists(pathWithEnv))
{
//Do what you want to do, both directories are available now.
}
else
{
System.IO.Directory.CreateDirectory(pathWithEnv);
//Do what you want to do, both directories are created.
}
}

Parallel.ForEach(...) System Out of Memory exception

I've looked at Parallel.ForEach - System Out of Memory Exception regarding this issue but not much of a solution was given. I'm very new to using Parallel.ForEach, so I'm trying to figure out what's going on.
Diagnostic tools caps out at 1023 repeating (I understand this is an x86 to x64 arch restriction, but I wanted to offer the program in both formats.) I also don't feel like any program should ever meet that threshold. When I compile the program in x64, I sit around 1.1-1.4GB with MaxDegree . For sake of testing, I am running GC.Collection() at the end of each Parallel.ForEach iteration (I understand this isn't good practice, I'm just trying to troubleshoot at this point.)
Here's what I'm seeing:
Now if I try to use a Partitioner method, such as:
var checkforfinished = Parallel.ForEach<ListViewItem>(Partitioner.Create(0,lstBackupUsers.Items.Count), lstBackupUsers.Items.Cast<ListViewItem>(), opts, name =>
The I get an error of:
"No overload for method 'ForEach' takes 4 arguments"
That's fine, I modify my Parallel.ForEach statement so it looks like this:
var checkforfinished = Parallel.ForEach(Partitioner.Create(0,lstBackupUsers.Items.Count), lstBackupUsers.Items, opts, name => (I removed my casts)
and then my ForEach method won't accept the statement because it wants me to explicitly tell it that it's addressing a listviewbox.items method.
I am so confused on what to do.
Do I create a Partitioner, and if I do, how do I make my Parallel.ForEach method understand how to address a listviewbox?
update 1
I want to try to give as many details as possible because this is just rough. I'm sure it's easy, I'm just overcomplicationg it by an nth degree.
I have my Parallel.ForEach(//) running in a background worker function. My DoWork process is over 300 lines (I'm not an expert in C#, I'm just putting things together for a program at work.)
Here are bullet points of its basic structure
User clicks a "Start backup" button as seen in the screenshot
Button begins a separate function that checks to see which method the user selected to grab a list of usernames from (LDAP or flat text file)
That function then sends off a bgw_dowork() request
Inside the DoWork request, it looks like a summary of:
Check preliminary statements (bgw.cancellationpending for example)
Move on to grabbing some settings from the configurationmanager.appsettings
Begin the "complex" Parallel.ForEach command which Reads the listbox record rows and foreach row performs a very long list of commands to complete an operation for one user
The entire program, especially bgw_dowork heavily uses Google's v3 Drive API to login as a user, grab a file as recorded by other functions that prepare the user directory to be backed up (separate functions which login as a user, record their files (and fileIds) and their directories/subdirectories) and the bgw_dowork performs a chunk of the actual download functionality, which then calls off to the other functions to finish moving the files after they have been downloaded.
The actual "code" I use is (and I promise it's not pretty...)

You can see where I initiate the Parallel.ForEach(...) and then see what it is in charge of doing. It's a lot, and I understand it's not pretty, so I appreciate constructive criticism.

How can I write a console application which can search Users Directory?

I asked guru but I still couldn't solve the problem that I have.
I want to write a console program searching certain files, like xls, doc or *pdf.
I wrote a code like this but when it comes to the say, Users Directory, it cates UnauthorizedAccessException.
How can I write a console application which can search Users Directory?
I set clickonce off and build it with manifest which requireAdministrator.
So, on Vista or 7, it runs as an administrator, with the elevation dialogue.
Here's the full code.

The error you're getting is caused by the file system permissions. The only way around would be to grant the credentials you're using access to the specified folders, run the application as 'Administrator' or run the application as the specific user for each User's folder.
