How do I move all subfolders in one directory to another folder in c#?

I have a directory with folders and files, and I want to move all the folders into another folder that's inside the directory.
I already can move all the files in the directory(Not including the files in the subfolders), but I am also trying to figure out how to move the subfolders.
string selectedDrive = comboBox1.SelectedItem.ToString();
string folderName = selectedDrive + #"\\Encrypted"; // Creates a directory under the selected drive.
System.IO.Directory.CreateDirectory(folderName);
string moveTo = (selectedDrive + #"\Encrypted");
String [] allFolders = Directory.GetDirectories(selectedDrive); //Should return folder
foreach (String Folder in allFolders)
{
if (!Directory.Exists(moveTo + Folder))
{
FileSystem.CopyDirectory(Folder, moveTo);
}
}
Instead, I have an error at this line FileSystem.CopyDirectory(Folder, moveTo);
saying the following: System.IO.IOException: 'Could not complete operation since source directory and target directory are the same.'

I have reworked your code to make it work in this way:
// source of copies, but notice the endslash, it's required
// if you use the string replace method below
string selectedDrive = #"E:\temp\";
string destFolderName = Path.Combine(selectedDrive, "Encrypted");
System.IO.Directory.CreateDirectory(destFolderName);
// All folders except the one just created
var allFolders = Directory.EnumerateDirectories(selectedDrive)
.Except(new[] { destFolderName });
// Loop over the sources
foreach (string source in allFolders)
{
// this line in framework 4.8,
string relative = source.Replace(selectedDrive, "");
// or this line if using NET Core 6
// string relative = Path.GetRelativePath(selectedDrive, source));
// Create the full destination name
string dest = Path.Combine(destFolderName, relative);
if (!Directory.Exists(dest))
{
FileSystem.CopyDirectory(source, dest);
}
}
Also noted now that you are using a root drive (F:) as source for the directories to copy. In this case you should consider that you have other folders not accessible or not copy-able. (For example the Recycle.bin folder). However you can easily add other exclusions to the array passed to the IEnumerable extension Except
....
.Except(new[] { destFolderName, "Recycle.bin" });

File not relocating correctly c#

I have my program setup to rename and store a file according to checkbox input. I used another stackoverflow post for my template. Only problem is when I tried setting it up for sub-folders, it never puts it in the correct folder. I have a label folder with two sub folders called L-Labels and B-Labels. The user checks which label type it is and the file gets renamed and placed in the according sub-folder. When I used breakpoint my variables are getting the correct value so I don't see what's wrong I have provided my variables and code for relocating the file. What is causing this to not put it in my sub-folder?
Varibales:
string oldPath = lblBrowseName.Text;
string newpathB = #"C:\Users\Public\Labels\B_Labels";
string newpathL = #"C:\Users\Public\Labels\L_Labels";
Method:
if (rChkBoxBizerba.Checked == true)
{
string newFileName = rtxtBoxNewVersion.Text;
FileInfo f1 = new FileInfo(oldPath);
if (f1.Exists)
{
if (!Directory.Exists(newpathB))
{
Directory.CreateDirectory(newpathB);
}
f1.CopyTo(string.Format("{0}{1}{2}", newpathB, newFileName, f1.Extension));
if (System.IO.File.Exists(lblBrowseName.Text))
System.IO.File.Delete(lblBrowseName.Text);
}

I would say this is the problem:
f1.CopyTo(string.Format("{0}{1}{2}", newpathB, newFileName, f1.Extension));
You declare your path but it doesn't have a trailing directory separator, so when you combine all the parts, as above, the actual result is invalid.
You really should use Path.Combine() to combine parts of paths together, this uses the correct directory separator and makes additional checks.
Try something like this:
// Build actual filename
string filename = String.Format("{0}{1}",newFileName, f1.Extension));
// Now build the full path (directory + filename)
string full_path = Path.Combine(newpathB,filename);
// Copy file
f1.CopyTo(full_path);

Check if directory exists with dynamic path

How can I check if the directory exists with a dynamic path (~) not a fixed path (C:)?
My code:
Soin_Id = Request.QueryString["SoinId"];
string path = #"~\Ordo\Soin_"+Soin_Id+#"\";
if (Directory.Exists(path))
{
ASPxFileManager_Ordo.Settings.RootFolder = path;
}
else
{
ASPxFileManager_Ordo.Settings.RootFolder = #"~\Ordo\";
}
With this condition, it's never true, even though the directory exists.

You need to use Server.MapPath to resolve dynamic path to physical path on server.
if (Directory.Exists(Server.MapPath(path)))
also consider using Path.Combine for concatenation of path.

Path from process name that is NOT running

I want to get full path from process name WITHOUT running the process.In otherwords- where C# gets absolute path when it is executing following :
Process.Start(startInfo);
startInfo does not contain absolute path.

The full path of the executable is resolved through the %PATH% environment variable. You can replicate the behaviour as follows:
var result = Environment.GetEnvironmentVariable("PATH")
.Split(';')
.Select(path => Path.Combine(path, "notepad.exe"))
.FirstOrDefault(path => File.Exists(path));
// result == "C:\\Windows\\system32\\notepad.exe"

Uses standard windows search policy: current folder and folders in the PATH environment variable.

Perhaps I misunderstood, but what about :
var fInfo = new FileInfo(startInfo.FileName);
var fullPath = fInfo.FullName;
?

How to get just folder path without the actual folder name?

I am wondering how I can get the file path, 1 level above the folder passed into a string.
So I have the following code:
foreach (DirectoryInfo directory in rootDir.GetDirectories())
{
string test = directory.FullName;
}
This returns the directory name including the folder name so it is returning this:
c:\test\FolderName
Where FolderName is the name of the directory object.
How would I get only c:\test?

You're looking for the directory.Parent property.

string test = Path.GetDirectoryName(directory.FullName);
