if (File.Exists(#"C:\\Users" + Environment.UserName + "\\Desktop\\test"))
{ /\
this file has no file extension
}
The file test has no extension and I need help to either move or rename this file to something with a extension
Having no extension has no bearing on the function.
Also, a rename is really just a move "in disguise", so what you want to do is
File.Move(#"C:\Users\Username\Desktop\test", #"C:\Users\Username\Desktop\potato.txt")
Please bear in mind the # before the string, as you haven't escaped the backslashes.
There's nothing special about extensionless files. Your code is broken because you use string concatenation to build a path and you're mixing verbatim and regular string literal syntax. Use the proper framework method for this: Path.Combine().
string fullPath = Path.Combine(#"C:\Users", Environment.UserName, #"Desktop\test");
if(File.Exists(fullPath))
{
}
You also should use the proper framework method to get the desktop path for the current user, see How to get a path to the desktop for current user in C#?:
string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string fullPath = Path.Combine(desktopPath, "test");
Then you can call File.Move() to rename the file, see Rename a file in C#:
if(File.Exists(fullPath))
{
string newPath = fullPath + ".txt";
File.Move(fullPath, newPath);
}
You can get all files without extension in this way:
var files = Directory.EnumerateFiles(#"C:\Users\Username\Desktop\")
.Where(fn => string.IsNullOrEmpty(Path.GetExtension(fn)));
Now you can loop them and change the extension:
foreach (string filePath in filPaths)
{
string fileWithNewExtension = Path.ChangeExtension(filePath, ".txt");
string newPath = Path.Combine(Path.GetDirectoryName(filePath), fileWithNewExtension);
File.Move(filePath, newPath);
}
As you can see, the Path-class is a great help.
Update: if you just want to change the extension of a single file that you already know it seems that Dasanko has already given the answer.

I receive every day a file with a specific pattern and extension, which I want to run under certain process. I want to check if there is any file in my folder, because otherwise I will do another task. So far I found that you can use a Script Task and do a File.Exist. However, I'm doing something wrong because it doesn't take the * as a wildcard.
Devoluciones_source is "C:\Users\us1\Folder\"
FileToSearch is "return"
My files:
return_20200102.csv
return_20200203.csv
String Filepath = Dts.Variables["$Project::Devoluciones_source"].Value.ToString() + Dts.Variables["User::FileToSearch"].Value.ToString() + "*csv";
if (
File.Exists(Filepath))
{
Dts.Variables["User::IsFound"].Value = 1;
}
I don't think File.Exits() accepts wildcards, it checks the literal filepath and will return false because C:\Users\us1\Folder\*.csv is not found.
What you could do instead is get the files in the folder C:\Users\us1\Folder\ and checking those agains a searchPattern using Directory.GetFiles(path, searchPattern)
Like this:
string dirPath = Dts.Variables["$Project::Devoluciones_source"].Value.ToString();
string fileName = Dts.Variables["User::FileToSearch"].Value.ToString();
// if you want to make sure the directory exists:
if(Directory.Exists(dirPath) {
string[] files = Directory.GetFiles(dirPath, fileName + "*.csv");
if(files.lenght > 0) {
// you can now iterate over each file that is found in the users directory that matches your pattern and do your logic.
}
}

It sounds simple but it is not. I am trying to move a file that i made it like this:
string newFileName = string.Format("{0}-{1}-{2}-t{3:00}-{4:00}.txt", 2013, 10, 5, 05, 06);
It is going to look like: 2013-10-5-05-06.txt, from the default directory (..\bin\debug\2013-10-5-05-06.txt) to another directory (c:\Users\Public\Folder). I want to keep the name of the file so that other files having almost the same name (small difference between) being moved to the same folder. I tried several methods (Path.Combine(), string.Concat()..) without success.
Just use this snippet
string CurrentFileNameAndPath; //the path the file you want to move
string newPath; //only the new the folderPath
System.IO.FileInfo FileYouWantToMove = new System.IO.FileInfo(CurrentFileNameAndPath);
string NewFileNameAndPath = newPath + "\\" + FileYouWantToMove.Name; //remember that using fullname will get the folder and filename
FileYouWantToMove.MoveTo(NewFileNameAndPath);
So lets use this as an example i have this file C:/Dir1/file1.txt and I want to change its directory to C:/Dir2/ right? then it will be like this
string CurrentFileNameAndPath = #"C:/Dir1/file1.txt";
string newPath = #"C:/Dir2/";
System.IO.FileInfo FileYouWantToMove = new System.IO.FileInfo(CurrentFileNameAndPath);
string NewFileNameAndPath = newPath + "\\" + FileYouWantToMove.Name;
FileYouWantToMove.MoveTo(NewFileNameAndPath);
the result will the that file in C:/Dir1/file1.txt will be now in C:/Dir2/file1.txt it have been moved and maintened the same file name and extension
Something like this is actually pretty trivial
var srcFile = "..\bin\debug\2013-10-5-05-06.txt";
var destFolder = Path.GetDirectoryName(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory));
var destFile = Path.Combine(destFolder, Path.GetFileName(srcFile));
File.Move(srcFile, destFile);
Just keep in mind that Move can throw various exceptions e.g. IOException / UnauthorizedAccessException etc. so it would be wise to handle these where appropriate.
Okay so I'm working with c# winforms and I have this code so far to create a ReadMe.txt and the folder itself
string folderName = #"C:\Test";
string text = "This is used Test.";
if (!System.IO.File.Exists(folderName))
{
System.IO.Directory.CreateDirectory(folderName);
File.Create(#"C:\Test\ReadMe.txt");
System.IO.File.WriteAllText(#"C:\Test\ReadMe.txt", text);
//Need to add Test.js to the folder C:\Test Here
}
As you can see above I need to add the Test.js to the folder.
Please and Thank you.
(P.S Yes it is added as a resource already)
Your code has a slight bug on line 3. It is using File.Exists instead of Directory.Exists to test if the Test Folder exists.
string folderName = #"C:\Test";
if (!Directory.Exists(folderName))
{
Directory.CreateDirectory(folderName);
}
string readMeFileName = Path.Combine(folderName, "ReadMe.txt");
string text = "This is used Test.";
File.WriteAllText(readMeFileName , text);
string jsFileName = Path.Combine(folderName, "Test.JS");
File.Copy("Test.js", jsFileName);
File.Copy Method is what you are looking for.
i want to create C# mass file renamer, here is my UI
i have created tes folder, inside of tes there's a file which is 1.txt.
i want to create my program to add prefix and suffix to the files, so 1.txt will become
prefix1suffix
but then i got an error
it's said file already exist though there's only one file on tes folder, which is 1.txt how do i make it work ? where's the error comes from ?
i have tried the following code
private void Rename(string prefix, string filepath, string suffix)
{
//i don't use prefix suffix yet to make sure if my function works
DirectoryInfo d = new DirectoryInfo(filepath);
FileInfo[] file = d.GetFiles();
try
{
foreach (FileInfo f in file )
{
File.Move(f.FullName,"stackoverflow");
}
}
catch (Exception e)
{
cmd.cetakGagal(e.ToString(), title);
}
cmd.cetakSukses("Rename Success", title);
}
and it returns same error as the second picture above.
the following picture is tes folder, there's nothing in tes folder except 1.txt
You are calling File.Move() with a full path for your sourceFileName and a relative path for your destFileName. The relative file path is relative to the current working directory and not to the source file path. I expect that a stackoverflow file exists in the current working directory, most likely created the first time you ran this code.
your File.Move is changing them all to StackOverflow not using the prefix and suffix. If you only have one file in the directory it shouldn't be an issue. Are you sure there is only 1 file?
public static void Move(
string sourceFileName,
string destFileName
)
Looking at this answer might be the clue as you are specifying relative path for the destination file. To obtain the current working directory, see GetCurrentDirectory
The sourceFileName and destFileName arguments are permitted to specify
relative or absolute path information. Relative path information is
interpreted as relative to the current working directory.
You should change
File.Move(f.FullName,"stackoverflow");
to
string fileName = f.Name.Replace(f.Extenstion,string.Empty);
string newFileName = string.Format("{0}{1}{2}",prefix,fileName,suffix);
string newFileWithPath = Path.Combine(f.Directory,newFileName);
if (!File.Exists(newFileWithPath))
{
File.Move(f.FullName,newFileWithPath);
}
The code above will give you that error since, after the first run through, "stackoverflow" exists as a file. Make sure that you check if the destination file exists (using File.Exists) before calling File.Move.
Since your goal is renaming, I would suggest using a test folder filled with files rather than using a piecemeal approach. See if something like this helps:
private void Rename(string prefix, string filepath, string suffix)
{
//i don't use prefix suffix yet to make sure if my function works
DirectoryInfo d = new DirectoryInfo(filepath);
FileInfo[] file = d.GetFiles();
try
{
foreach (FileInfo f in file )
{
f.MoveTo(#filepath + #"\" + prefix + f.Name.Insert(f.Name.LastIndexOf('.'),suffix));
}
}
catch (Exception e)
{
cmd.cetakGagal(e.ToString(), title);
}
cmd.cetakSukses("Rename Success", title);
}
on a side note using a listview to display the filenames and the changes before they're committed will help prevent unwanted changes.
What is the simplest way to get the directory that a file is in? I'm using this to set a working directory.
string filename = #"C:\MyDirectory\MyFile.bat";
In this example, I should get "C:\MyDirectory".
If you've definitely got an absolute path, use Path.GetDirectoryName(path).
If you might only get a relative name, use new FileInfo(path).Directory.FullName.
Note that Path and FileInfo are both found in the namespace System.IO.
System.IO.Path.GetDirectoryName(filename)
Path.GetDirectoryName(filename);
You can use System.IO.Path.GetDirectoryName(fileName), or turn the path into a FileInfo using FileInfo.Directory.
If you're doing other things with the path, the FileInfo class may have advantages.
You can use Path.GetDirectoryName and just pass in the filename.
MSDN Link
If you are working with a FileInfo object, then there is an easy way to extract a string representation of the directory's full path via the DirectoryName property.
Description of the FileInfo.DirectoryName Property via MSDN:
Gets a string representing the directory's full path.
Sample usage:
string filename = #"C:\MyDirectory\MyFile.bat";
FileInfo fileInfo = new FileInfo(filename);
string directoryFullPath = fileInfo.DirectoryName; // contains "C:\MyDirectory"
Link to the MSDN documentation.
You can get the current Application Path using:
string AssemblyPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location).ToString();
First, you have to use System.IO namespace. Then;
string filename = #"C:\MyDirectory\MyFile.bat";
string newPath = Path.GetFullPath(fileName);
or
string newPath = Path.GetFullPath(openFileDialog1.FileName));
You can use Path.GetFullPath for most of the case.
But if you want to get the path also in the case of the file name is relatively located then you can use the below generic method:
string GetPath(string filePath)
{
return Path.GetDirectoryName(Path.GetFullPath(filePath))
}
For example:
GetPath("C:\Temp\Filename.txt") return "C:\Temp\"
GetPath("Filename.txt") return current working directory like "C:\Temp\"
In my case, I needed to find the directory name of a full path (of a directory) so I simply did:
var dirName = path.Split('\\').Last();
