I have some temporary files in Temporary Internet file folder i need copy them to my folder,i see the file in folder but function File.Exists no.
My function
string InternetTempPath= Environment.GetFolderPath(Environment.SpecialFolder.InternetCache);
string TempFilePath = Path.Combine(InternetTempPath, "MyFile.pdf");
bool Isfile = System.IO.File.Exists(TempFilePath);
don't see the files that i am looking for.
Files in Temporary Internet file folder do not have names they can't even be renamed,I think i need to look files by Internet Adress,or Last Checked.They not like ordinary files.
How can i find this files?
Are you missing the file extension?
Your file is probably "MyfileName.txt" not just "MyfileName".
Try adding the file extension and seeing if that works...
string TempFilePath= Environment.GetFolderPath(Environment.SpecialFolder.InternetCache);
TempFilePath+="MyfileName.txt";
bool Isfile = System.IO.File.Exists(TempFilePath);
P.S. appending strings is not recommended in C# the way you're using +=. If these were normal strings I'd recommend using a StringBuilder to combine them, as you're dealing with Paths, try using Path.Combine:
string TempFilePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache), "MyfileName.txt");
bool Isfile = System.IO.File.Exists(TempFilePath);
Solution 1:
You need to add backward slash after the Temparary internet folder path.
TempFilePath += "\\myfile.txt";
Solution 2: (Recommended)
You can use Path.Combine() to combine the paths as below:
string newpath = Path.Combine(TempFilePath,"myfile.txt");
The problem is most likely the miss of slashes. You should use Path.Combine instead of concatenating the file path yourself:
string TempFilePath = Environment.GetFolderPath(Environment.SpecialFolder.InternetCache);
string filePath = Path.Combine(TempFilePath, "MyfileName");
bool Isfile = System.IO.File.Exists(filePath);
There's a hidden folder inside that location called Content.IE5, and that will contain several randomly named folders with the actual temporary internet files inside them.
var path = Path.Combine(
Environment.GetFolderPath(Environment.SpecialFolder.InternetCache),
"Content.IE5");
Here is answer

I'm looking to make a program to make my life easier, I need to be able to easily select a folder, which I can do, I don't need help with that. I want to take the directory of a folder, and put that folder into a new folder with a specified name, and then zip up that folder into a zip format in which I can change the name and filetype of. Is this possible in vanilla C#? I've only ever done files for text and I've never looked at moving and packaging files. SO I'm really clueless, I'd just like to be guided into the right direction.
Edit: I found this code online, but I need to put the folder inside another folder, may I adapt upon this to do so?
string startPath = #"c:\example\start";
string zipPath = #"c:\example\result.zip";
string extractPath = #"c:\example\extract";
ZipFile.CreateFromDirectory(startPath, zipPath);
ZipFile.ExtractToDirectory(zipPath, extractPath);
So, after an extended chat discussion, here's what we've established.
The goal is to put the contents of a source directory into a zip with the following structure:
- Payload
|- name of source
|-- contents of source
Okay, so, starting from an input path called startPath:
var parent = Path.GetDirectoryName(startPath);
var payload = Path.Combine(parent, "payload");
Directory.CreateDirectory(payload); // ensure payload ex
Directory.Move(startPath, Path.Combine(payload, Path.GetFileName(startPath));
var zipPath = Path.Combine(parent, "export.zip");
File.Delete(zipPath);
ZipFile.CreateFromDirectory(payload , zipPath, CompressionLevel.Optimal, true);
The key is that true in the CreateFromDirectory call, that puts the entries in the archive under a directory with the same name as the directory being zipped (in this case, "payload"). Feel free to change CompressionLevel to other values if you want.
Now, this has the side effect of actually physically moving the source directory, which might not be the best user experience. If you want to avoid that, you'll have to basically do what ZipFile.CreateFromDirectory does by hand, which is to enumerate the source directory yourself and then copy the files into the zip archive (in which case you can name those files whatever you want):
var parent = Path.GetDirectoryName(startPath);
var zipPath = Path.Combine(parent, "export.zip");
File.Delete(zipPath);
using var zip = ZipFile.Open(zipPath, ZipArchiveMode.Create);
foreach(var file in Directory.EnumerateFiles(startPath, "*", SearchOption.AllDirectories))
{
// get the path of the file relative to the parent directory
// this gives us a path that starts with the source directory name
// e.g. C:\example\start\file.txt -> start\file.txt
var relativePath = Path.GetRelativePath(parent, file);
// construct the path of the entry in the archive
// this is "Payload", and then the relative path of the file
// we need to fix up the separators because zip entries use /
// e.g. start\file.txt -> Payload/start/file.txt
var entryPath = Path.Combine("Payload", relativePath).Replace(Path.DirectorySeparatorChar, '/');
// put the file in the archive
// to specify a compression level, pass it as the third parameter here
zip.CreateEntryFromFile(file, entryPath);
}
I have xml files that contain href file paths to images (e.g. "....\images\image.jpg"). The hrefs contain relative paths. Now, I need to extract the hrefs to the images and turn them into absolute paths in the file system.
I know about the GetFullPath method, but I tried it and it only seems to work from the CurrentDirectory set, which appears to be C: so I don't see how I could use that. And still, I have the absolute path of the file containing the hrefs, and the href relative paths, so since it is a simple task for me to count back the number of "....\" parts based on the absolute path of the containing file, it seems there must be a way to do this programmatically as well.
I'm hoping there's some simple method I just don't know about! Any ideas?
string exactPath = Path.GetFullPath(yourRelativePath);
works
Assuming you know the real directory the XML file lives in use Path.Combine, e.g.
var absolute_path = Path.Combine(directoryXmlLivesIn, "..\images\image.jpg");
If you want to get back the full path with any ..'s collapsed then you can use:
Path.GetFullPath((new Uri(absolute_path)).LocalPath);
This worked.
var s = Path.Combine(#"C:\some\location", #"..\other\file.txt");
s = Path.GetFullPath(s);
It`s best way for convert the Relative path to the absolute path!
string absolutePath = System.IO.Path.GetFullPath(relativePath);
You can use Path.Combine with the "base" path, then GetFullPath on the results.
string absPathContainingHrefs = GetAbsolutePath(); // Get the "base" path
string fullPath = Path.Combine(absPathContainingHrefs, #"..\..\images\image.jpg");
fullPath = Path.GetFullPath(fullPath); // Will turn the above into a proper abs path
Have you tried Server.MapPath method. Here is an example
string relative_path = "/Content/img/Upload/Reports/59/44A0446_59-1.jpg";
string absolute_path = Server.MapPath(relative_path);
//will be c:\users\.....\Content\img\Upload\Reports\59\44A0446_59-1.jpg
This worked for me.

In my project, I added a folder with files in it. They all have a local path.
I want to have a string array with all the paths to all of those files, but I have no clue how to do that.
I tried this, but it only returns strings in the format of "namespace+project+foldername+name".
string[] test = Assembly.GetExecutingAssembly().GetManifestResourceNames();
What I want is the full path:
D:\Projectname\Project\Folder\file.ext
It would also help to get the reference/path to the folder, because then I could get the files with:
System.IO.Directory.GetFiles();
Anyone got an idea?
Try This.
string path= Path.GetDirectoryName(Path.GetDirectoryName(System.IO.Directory.GetCurrentDirectory()));
try this
string[] files= Directory.GetFiles(#"directory");
and if you want to get your project directory use
string path = Directory.GetCurrentDirectory();

Currently i have this, i need to find a way to make it so that as opposed to writing out the directory of the txt files, i want it to create them in the same location as the exe and access them.
basically i want to change these lines
string location = #"C:\Users\Ryan\Desktop\chaz\log.txt";
string location2 = #"C:\Users\Ryan\Desktop\chaz\loot.txt";
to something that can be moved around your computer without fear of it not working.
If you're saving the files in the same path as the executable file then you can get the directory using:
string appPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
Normally you wouldn't do that, mostly because the install path will be found in the Program Files folders, which require Administrative level access to be modified. You would want to store it in the Application Data folder. That way it is hidden, but commonly accessible through all the users.
You could accomplish such a feat by:
string path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
string fullPath = Path.Combine(path, #"NameOfApplication");
With those first two lines you'll always have the proper path to a globally accessible location for the application.
Then when you do something you would simply combine the fullPath and the name of the file you attempt to manipulate with FileStream or StreamWriter.
If structured correctly it could be as simple as:
private static void WriteToLog(string file)
{
string path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
string fullPath = Path.Combine(path, #"NameOfApplication");
// Validation Code should you need it.
var log = Path.Combine(fullPath, file);
using(StreamWriter writer = new StreamWriter(log))
{
// Data
}
}
You could obviously structure or make it better, this is just to provide an example. Hopefully this points you in the right direction, without more specifics then I can't be more help.
But this is how you can access data in a common area and write out to the file of your choice.
