Get image file path from resources

I have an image file day.jpg in Resources folder and I want to access it in the code as string path not as byte[] img
Here's what I have tried.
string dayWallpaper = Assembly.GetExecutingAssembly().Location + #"..\..\Resources\day.jpg";
// Didn't found it
string dayWallpaper = Resource.day;
// Outputs byte[] and gives me an error
Then I tried to convert the byte[] to String didn't work as well
static byte[] SliceMe(byte[]? source, int pos)
{
byte[]? destfoo = new byte[source.Length - pos];
Array.Copy(source, pos, destfoo, 0, destfoo.Length);
return destfoo;
}
static string ByteToPath(path)
{
String file = Encoding.Unicode.GetString(SliceMe(path, 24)).TrimEnd("\0".ToCharArray());
return file
}
Outputs black screen
Later I search for the file
if (File.Exists(dayWallpaper))
{
do stuff
}
else
{
Console.WriteLine("File does not exists");
}
And gives me the else statement.

In the answer you posted to your question, the fact that your relative path works is an "accident" that would fail on any other device deploying your app because without the existence of the source code project the path doesn't exist. One good option is to mark the day.jpg file as Copy to Output Directory at which point most installer bundlers will pick it up and deploy it in your setup.exe, msi etc. If you are specifically using the Visual Studio IDE, you would do it like this:
Now, at runtime, to acquire the path to the copied file:
var srce = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Resources", "day.jpg");
However, there is more work to be done, because you state that you "want to store the image in a folder in the executable and the user could add more images later on." The present location of the file is not suitable for that purpose, so I would recommend the additional step of creating an AppData entry for the user to store their created content.
// Obtain a folder that "the user could add to later on".
var appData =
Path.Combine(
Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData),
typeof(Program).Assembly.GetName().Name
);
Directory.CreateDirectory(appData);
Since you mention wanting to store the day.jpg image in that folder, go ahead and copy it to the AppData location (if not already there from a previous run of your app).
var dest = Path.Combine(appData, "day.jpg");
// Copy the image (if it's not there already) into folder that the user can add to.
if (!File.Exists(dest))
{
File.Copy(
sourceFileName: srce,
destFileName: dest
);
}
Alternatively, you could set the BuildAction to EmbeddedResource and manipulate the file as a byte stream and achieve the same end result.

I managed to do it this way
string resourcePath = Path.GetFullPath(Assembly.GetExecutingAssembly().Location + #"\..\..\..\..\Resources");
string dayWallpaper = resourcePath + #"\day.jpg";

How to create file text in "AppData\Roaming" for any user in C#

I'd like save date my app but I'm not knowing if app save for different users, Example if "andy" I can't use ("C:\Users\Game maker\AppData\Roaming") ,So How to create file in "AppData\Roaming\MaxrayStudyApp" for any user .
Computer myComputer = new Computer();
myComputer.FileSystem.WriteAllText(#"C:\Users\Game maker\AppData\Roaming\MaxrayStudy\data.txt","", false);

Almost a duplicate of this one: Environment.SpecialFolder.ApplicationData returns the wrong folder
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
That should get the folder you need then use Path.Combine() to write to a directory in that folder.
var roamingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
var filePath = Path.Combine(roamingDirectory, "MaxrayStudy\\data.txt");

I restart my windows and I write this
string filePath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
filePath= (filePath+#"\MaxrayStudyApp\data.txt");
string path =Convert.ToString(filePath);
using (System.IO.StreamWriter file =
new System.IO.StreamWriter(filePath,false)){
file.WriteLine(" XP : 0");}

Create Directory will multiple names passed by parameter C#

I have to create multiple folders as e.g.
Directory.CreateDirectory("PATH\\" + _year + "filetosave.txt");
while "PATH\\" is the full path where the folder will reside, _year is the parameter and "filetosave.txt" is the file which is to be saved in respective folder.
And at run time, it should create respective folders with years in the folder name containing respective files to save.
Whereas .CreateDirectory() method only accepts string path or string path, security access as parameters.
How will we create these parameterized folders?
How can we make a check that a specified directory already exists or not?

var path = Path.Combine("PATH\\", _year.ToString(), "filettosave.txt");
Directory.CreateDirectory(path);
Directory.CreateDirectory
Creates all directories and subdirectories in the specified path unless they already exist.
Emphasis mine.

As commented, use Path.Combine when trying to build system paths:
var root = "Path";
var year = "2016";
var filename = "filetosave.txt";
var path = Path.Combine(root, year, filename);
// path = Path\2016\filetosave.txt
Directory.CreateDirectory(path);

In general, use System.IO.Path.Combine to build paths. It simplifies this task.
string dir = System.IO.Path.Combine(rootPath, _year.ToString());
Directory.CreateDirectory(dir);
string file = System.IO.Path.Combine(dir, "filetosave.txt");
FileStream fs = File.Create(file)

Saving images to a project folder in asp.net/c#

In my method, I'm trying to save an image in a folder in the directory of my project. I have tried just putting the direct filepath of the folder, but that gives me an error when the project runs.
Is there a built-in extension of some kind in c# that would allow me to save this image in a folder in my directory; or way to simply access my directory without drilling to where my project is saved on my computer?
private void CreateBarcode()
{
var bitmapImage = new Bitmap(500,300);
var g = Graphics.FromImage(bitmapImage);
g.Clear(Color.White);
UPCbarcode barcode = new UPCbarcode(UPCbarcode.RandomGeneratedNumber(), bitmapImage, g);
string filepath=#"images/image1.jpg";
bitmapImage.Save(filepath,System.Drawing.Imaging.ImageFormat.Jpeg);
}

You can always use the AppData folder,
string path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

Assuming the "Image" folder is in the root directory of your Project use:
Server.MapPath("~/Image" + filename)
you can check if the file already exist at a location by :
if (!File.Exists(filePath))
{
// Your code to save the file
}

I can guess that there is similarity in the name of the image file
try putting it under a different name
like
string filepath = # "images / blabla or AI.jpg";

Use this
string filepath= Application.StartupPath + "\images\image1.jpg";
bitmapImage.Save(filepath,System.Drawing.Imaging.ImageFormat.Jpeg);

Copy and overwrite files between two folders(one shared)

I'm making a small application that have to take all the files from a shared folder and copy them in the current folder(the once from where the application it's runned).
One month ago this code was fine:
string seprin_address = #"\\PC-SEPRIN\2port\";
SimpleCopy(seprin_address);
public void SimpleCopy(string sourcePath){
try{
string fileName = "";
string targetPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);
bool path = false;
string real_target = "";
for(int i = 0; i < targetPath.Length; i++){
if(targetPath[i] == 'C'){
path = true;
}
if(path){
real_target += targetPath[i];
}
}
// Use Path class to manipulate file and directory paths.
string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
string destFile = System.IO.Path.Combine(targetPath, fileName);
// To copy a folder's contents to a new location:
// Create a new target folder, if necessary.
/*if (!System.IO.Directory.Exists(targetPath))
{
System.IO.Directory.CreateDirectory(targetPath);
}*/
// To copy a file to another location and
// overwrite the destination file if it already exists.
//System.IO.File.Copy(sourceFile, destFile, true);
// To copy all the files in one directory to another directory.
// Get the files in the source folder. (To recursively iterate through
// all subfolders under the current directory, see
// "How to: Iterate Through a Directory Tree.")
// Note: Check for target path was performed previously
// in this code example.
if (System.IO.Directory.Exists(sourcePath))
{
string[] files = System.IO.Directory.GetFiles(sourcePath);
// Copy the files and overwrite destination files if they already exist.
foreach (string s in files)
{
// Use static Path methods to extract only the file name from the path.
fileName = System.IO.Path.GetFileName(s);
destFile = System.IO.Path.Combine(targetPath, fileName);
System.IO.File.Copy(s, destFile, true);
}
}
else
{
MessageBox.Show("Error");
}
// Keep console window open in debug mode.
}
catch(Exception e_p){
lbabel.Text = e_p.Message;
}
}
Now i get the "URI not supported error" when the file.copy it's called.
I think its supernatural but if you have any other ideas i'm all ears.

I would find out if the URI not supported is complaining about source or destination. I would also check to make sure the user that this is running as has permission to the directories in question. Could the users permissions have changed? I have had occasion where I had jobs in scheduled tasks where the user was set and later the password was changed for the user but not on the scheduled task. The same could be true if this is written as a service with a specific user.

as you are saying it was working fine one month ago, there can be two possibilities which is restricting you from accessing the Path.
1.Remote PC Hostname PC-SEPRIN might havebeen changed.Please check the remote pc hostname.
2.check the Shared Folder 2port path properly.
if somebody changes shared folder name or deletes it, you can not access it.
and also please check whether you have permissions to access it or not.
