Restrict my code to write to a specific folder C#

I got a folder in C called "donotcopy". I want to protect it and no matter what not to be allowed to create files within.
My intuitive solution was just to create a str with same name and where user enters a destination it just checks if it's the same.
Example:
class FileCreation
{
public static void Main()
{
string notallowed = ("c:\\donotcopy");
string filename = ("Nick.txt");
Console.WriteLine("Enter the full path to create an empty file.");
string path = Console.ReadLine();
path = path.ToLower();
while (notallowed == path)
{
Console.WriteLine("The chosen path is not allowed please try another one.");
path = Console.ReadLine();
path = path.ToLower();
}
using (FileStream fs = File.Create(path + filename)) ;
}
}
The problem is if the user enters the destination as "c:.\donotcopy" it will still create the file inside the restricted folder.

You can make use of the DirectoryInfo class, which will allow you to retrieve info about the full path of a directory.
class FileCreation
{
public static void Main()
{
string notallowed = ("c:\\donotcopy");
string filename = ("Nick.txt");
Console.WriteLine("Enter the full path to create an empty file.");
DirectoryInfo directory = new DirectoryInfo(Console.ReadLine());
while (notallowed.Equals(directory.FullName, StringComparison.InvariantCultureIgnoreCase))
{
Console.WriteLine("The chosen path is not allowed please try another one.");
directory = new DirectoryInfo(Console.ReadLine());
}
string fullPath = Path.Combine(directory.FullName, filename);
using (FileStream fs = File.Create(fullPath)) ;
}
}

ziparchive text files in c#

I have a folder full of text files. I want to zip each one individually. If there are First.txt and Second.txt in the folder C:\Temp\raw
I want to zip First.txt as First.zip and move it to C:\Temp\Done and Second.txt zipped as Second.zip and move it to C:\Temp\Done. This is the code I have
-- SourcePath = C:\Temp\raw tempPath = C:\temp\Done in app.config
public static DirectoryInfo sourcePath = new DirectoryInfo(ConfigurationManager.AppSettings["sourcePath"].ToString());
public static string tempPath = ConfigurationManager.AppSettings["tempPath"].ToString();
var files = System.IO.Directory.GetFiles(sourcePath.ToString(), "*.txt").OrderBy(f => f);
string zipfilename = "";
try
{
foreach (var fPath in files)
{
string fileNameNoPath = Path.GetFileName(fPath);
string destFile = Path.Combine(tempPath, fileNameNoPath);
System.IO.File.Move(fPath, destFile);
ZipFile.CreateFromDirectory(tempPath, tempPath, CompressionLevel.Fastest, true);
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
I am getting errors. System.UnauthorizedAccessException: Access to the path 'C:\Temp\Done' is denied
I do have access to C:\temp\folder and I am running as admin
Can someone guide me
Thanks

Downloading from the internet link to the dynamically created folder. How is the path to this folder?

enter image description here
I am creating a dynamic folder as seen in the design in the image. I need to download two file types of data in a link to this folder I created, but how can I download it to the folder I created?
klasor = textBox1.Text;
var yol = Directory.CreateDirectory(AppDomain.CurrentDomain.BaseDirectory + #"Beyza\source\" + klasor);
In this way, I create a folder in the 'klasor' variable.
public void indirButon_Click(object sender, EventArgs e)
{
string fileName = "C:\\Users\\Hilal Beyza\\Desktop\\projeler\\LinkProgram\\LinkProgram\\bin\\Debug\\Hilal Beyza\\yol\\webcams.mp4";
WebClient web = new WebClient();
web.DownloadFileCompleted += new AsyncCompletedEventHandler(Dosyaİndirme);
Uri DosyaAdresi = new Uri(label3.Text);
web.DownloadFile(DosyaAdresi, fileName);
}
I am giving my downloaded file a static path as above. How can I transfer this to the file I created?

Recommendations: When you write a program try to name components with a logic name, example txtUri, txtFolderName, btnDownload, this facilitates understanding.
If you have a File Name and Dynamic Folder it's possible.
public void indirButon_Click(object sender, EventArgs e)
{
string fileName = GetFileName("webcams.mp4");
WebClient web = new WebClient();
web.DownloadFileCompleted += new AsyncCompletedEventHandler(DosyaIndirme);
Uri DosyaAdresi = new Uri(label3.Text);
web.DownloadFile(DosyaAdresi, fileName);
}
This method Get File Name with new Dynamicly Folder.
private static string GetFileName(string fileName)
{
string klasor = textBox1.Text;
string directoryPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, #"Hilal Beyza\source\", klasor);
if (!Directory.Exists(directoryPath))
Directory.CreateDirectory(directoryPath);
return Path.Combine(directoryPath, fileName);
}
If User pass complete path you need remove adapt the directoryPath
string directoryPath = Path.Combine(textBox1.Text);

Create / open directory with creadentials in Windows

I want create directory with Active directory user credentials, only that user has access for directory manipulation like opening listing files, reading files etc.
public void CreateDirectory(int value)
{
string drive = Directory.GetDirectoryRoot(HostingEnvironment.ApplicationPhysicalPath);
string path = "D://" + "4524l";
DirectoryInfo dinfo = Directory.CreateDirectory(path);
string domainAndUsername = "456456.com" + #"\" + "guserone";
DirectoryEntry entry = new DirectoryEntry("LDAP://124.com", domainAndUsername, "a55in123*");
//Bind to the native AdsObject to force authentication.
object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + "guserone" + ")";
search.PropertiesToLoad.Add("cn");
SearchResult result = search.FindOne();
DirectorySecurity myDirectorySecurity = dinfo.GetAccessControl();
//myDirectorySecurity.SetOwner(newUser);
myDirectorySecurity = RemoveExplicitSecurity(myDirectorySecurity);
dinfo.SetAccessControl(myDirectorySecurity);
myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(domainAndUsername,
FileSystemRights.FullControl, AccessControlType.Allow));
dinfo.SetAccessControl(myDirectorySecurity);
myDirectorySecurity.SetAccessRuleProtection(true, false);
}
private static DirectorySecurity RemoveExplicitSecurity(DirectorySecurity directorySecurity)
{
AuthorizationRuleCollection rules = directorySecurity.GetAccessRules(true, false, typeof(System.Security.Principal.NTAccount));
foreach (FileSystemAccessRule rule in rules)
directorySecurity.RemoveAccessRule(rule);
return directorySecurity;
}

Assuming you are dealing with a simple scenario, you are probably looking for Directory.CreateDirectory(string path, DirectorySecurity directorySecurity), which you can find documented here.
There's a decent example there that includes creation of basic access controls.

File.Copy - DirectoryNotFoundException was unhandled

When I use this code it doesn't throw any errors but it still doesn't copy anything. Any ideas?.
//string spath = string.Format("S:\\ 0A36303 / user:admin");
DateTime theDate = dateTimePicker1.Value.Date;
DirectoryInfo Dir = new DirectoryInfo("S:");
string dircreate = string.Format(#"N:\{0:MM-dd-yyyy}\" + label1.Text + "LogFiles", dateTimePicker1.Value.Date, label1.Text);
DirectoryInfo target = new DirectoryInfo(dircreate);
FileInfo[] fis = Dir.GetFiles( ".txt", SearchOption.AllDirectories);
foreach (FileInfo fi in fis)
{
if (fi.LastWriteTime.Date == theDate)
{
File.Copy(fi.FullName, target.FullName + #"\" + fi.Name, true);
}
}
}
}
}

Try using the full UNC path to access the file:
DirectoryInfo Dir = new DirectoryInfo(#"\\server\\share\\pathtofile");

Two possible problems come to mind:
The S:\PC.log file doesn't exist => you cannot copy non-existent file
The process you are executing your code under doesn't have read permission to the specified folder (S:). Looks like a network share. If you are running this code inside an ASP.NET application the process probably doesn't have read permissions to this remote share => you cannot copy a file that you don't have permissions to access.
