I want to copy a file to a directory. I thought it would be a simple enough process.
This is the code im using:
string strSrcPath = "C:\Users\Documents\Development\source\11.0.25.10\",
strDstPath = "C:\Users\Documents\Development\testing\11.0.25.10\",
strFile = "BuildLog.txt"
File.Copy(Path.Combine(sourcePath, sourceFile), strDstPath);
The problem here is that when i'm doing the File.Copy it wants to copy one file to another, but I dont want to do that since the file does not exist in the destination path. Therefore I get thrown an error which states something along the lines of 'Cannot copy, strDstPath is a destination not a file"
Was there something I could use instead of File.Copy to copy a file that doesnt exist in the destinaion from the source to destination?
The problem is that the parameters are the source filename and the destination filename. You are passing a destination directory and the program is confused because you can't make the file into a directory.
Use instead:
File.Copy(Path.Combine(strSrcPath , strFile ), Path.Combine(strDstPath, strFile);
You seem to be passing some wrong parameter to the Path.Combine (the second one). It should be strFile instead of sourceFile which is quite unclear where is it coming from.
And you also need to provide a filename for the destination folder:
File.Copy(Path.Combine(sourcePath, strFile), Path.Combine(strDstPath, strFile));
You also need to escape the \ characters in your string because your code will probably not compile. This could be done by either using \\ or by using the # character at the beginning of your string.
string strSrcPath = #"C:\Users\Documents\Development\source\11.0.25.10\",
strDstPath = #"C:\Users\Documents\Development\testing\11.0.25.10\",
strFile = "BuildLog.txt"
File.Copy(Path.Combine(sourcePath, strFile), Path.Combine(strDstPath, strFile));
Also make sure that the destination folder you specified exists. If it doesn't exist you need to create it first (using the Directory.CreateDirectory method).
You have to specify a filename for your destination
so
File.Copy("XMLFile1.xml", #"c:\temp");
will fail where
File.Copy("XMLFile1.xml", #"c:\temp\XMLFile1.xml");
will not

I'm using the following code just to copy a file from a smaller filepath into a longer file path (> 260 characters).
string dbCDataPath = Path.Combine(DYRECTORY_WITH_GUARANTEE_ACCESS,Path.GetFileName(pathFileName));
string targetFile = Path.Combine(Path.GetDirectoryName(pathFileName), Path.GetFileName(pathFileName));
File.Copy(dbCDataPath, targetFile, true);
I'm getting Could not find a part of the path error and I don't know why I have double checked both the source and the destination folders, both exists.
Any help will be highly appreciated.
You need to call File.Copy like this:
File.Copy(targetFile, dbCDataPath, true);
The first parameter of this method is sourceFile you want to copy, the second parameter is destination path.
File.Copy(#"my program\\subfolder\\what i want to copy.txt", "C:\\Targetlocation");
How can i copy a text file from one folder to another using relative path.
To execute the File.Copy the source and destination will be a valid file path. in your case the destination is a folder not File. in this case you may get some exception like
Could not find a part of the path 'F:\New folder'
While executing the application, the current directory will be the bin folder. you need to specify the relative path from there. Let my program/subfolder be the folders in your solution, so the code for this will be like this:
string sourcePath = "../../my program/subfolder/what i want to copy.txt";
string destinationPath = #"C:\Targetlocation\copyFile.txt"
File.Copy(sourcePath, destinationPath );
Where ../ will help you to move one step back from the current directory. One more thing you have to care is the third optional parameter in the File.Copy method. By passing true for this parameter will help you to overwrite the contents of the existing file.Also make sure that the folder C:\Targetlocation is existing, as this will not create the folder for you.
File.Copy(#"subfolder\\what i want to copy.txt", "C:\\Targetlocation\\TargetFilePath.txt");
The sourceFileName and destFileName parameters can specify relative or
absolute path information. Relative path information is interpreted as
relative to the current working directory. This method does not
support wildcard characters in the parameters.
File.Copy on MSDN
Make sure your target directory exists. You can use Directory.CreateDirectory
Directory.CreateDirectory("C:\\Targetlocation");
With Directory.CreateDirectory(), you don't have to check if the directory exists. From documentation:
Any and all directories specified in path are created, unless they
already exist or unless some part of path is invalid. The path
parameter specifies a directory path, not a file path. If the
directory already exists, this method does nothing.
// Remove path from the file name.
string fName = f.Substring(sourceDir.Length + 1);
try
{
// Will not overwrite if the destination file already exists.
File.Copy(Path.Combine(sourceDir, fName), Path.Combine(backupDir, fName));
}
You can provide the relative path from your current working directory which can be checked via Environment.CurrentDirectoy.
For example if your current working directory is D:\App, your source file location is D:\App\Res\Source.txt and your target location is D:\App\Res\Test\target.txt then your code snippet will be -
File.Copy(Res\\Source.txt, Res\\Test\\target.txt);

Given a filesystem path, is there a shorter way to extract the filename without its extension?

Closed 5 years ago.
I have searched everywhere to find this answer but still can't find it.
I have a file in my Documents folder. I create and append a file with the same content in another folder. (Let's say Downloads). How do I give the new file the same name as the old file?
I just need help with naming the new file the same as the old. I already have it appending and sending to another folder. I'm using StreamReader to read the old file and StreamWriter to create the new file. I dont want to hard code a path to rename it, because there may be multiple files that I need to read.
It's not clear exactly what you're asking for, but I'll take a stab at it.
If you're using something like the File.Copy() method, then you just have to use the full file path for both the source and destination. If you're passing a string value with the full path to the file, you can get just the file name using Path.GetFileName()
Here's an example based on my loose guesstimation of your question:
var filename = Path.GetFileName(sourcePath);
var newPath = $"{destinationFolderPath}\\{filename}";
File.Copy(sourcePath, newPath);

There is a static function Path.GetFilename, which returns a file name contained in a path passed as the argument:
var filename = Path.GetFilename(#"c:\file.txt"); // filename = "file.txt"
Path also contains other useful funtions, such as GetFilenameWithoutExtension.
Use Path.GetFileName i.e.
// The path you want to copy the filename of.
// C:/Users/<username>/Documents/<some file> in your case.
var srcPath = //...
// The directory you want to copy to.
// C:/Users/<username>/Downloads in your case.
var destDir = //...
// Different directory, same filename.
var destPath = Path.Combine(destDir, Path.GetFileName(srcPath));
How can I check if a file exists or not in the directory the executable is?
I know how I could code it like this.
string path = Application.StartupPath + "config.cfg"
if(!FileExists(path))
{
//create the file
}
But the problem I am facing is that, the file is created every single time, even when the file exists, overwriting the data of the cfg file with the default ones.
You are not creating the possible file path properly. Use Path.Combine like:
string path = Path.Combine(Application.StartupPath, "config.cfg");
You are getting a path without terminating \ from Application.StartupPath, later you are concatenating the file name to it, This will create an invalid path, and since that doesn't exist, you check fails.
Just to show, the actual reason for getting the error, you can fix your code like:
string path = Application.StartupPath +"\\"+ "config.cfg";
But, do not use the above code, instead use Path.Combine to join multiple path elements.
I want to save image into a folder and the path of the folder to the database.
I have done this with File.Copy(filepath) command but it is giving me error when a file with the same name already exists there.
Second thing in this command is that I have to provide a filename in it from which it is copying the file. If I am modifying a record and not the image then it is giving error that file source cannot be empty.
I have also tried Picture1.image.save(filename) but I have not found any command to overwrite the existing file.
Please help me by providing a simplest way to do all this.
There's an overload to the File.Copy() method that accepts a bool which will determine whether to overwrite any existing files with the same name.
http://msdn.microsoft.com/en-us/library/9706cfs5.aspx
File.Copy(sourceFileName, destFileName, true) Will force an overwrite of existing file.
Refer MSDN File.Copy
if(File.Exists(destinationFileName))
{
File.Delete(destinationFileName);
}
File.Copy(sourceFileName, destinationFileName);
sourceFileName shoudl be the full path of the source file(including the file name).
destinationFileName should be the fullpath (including the filename) where you want to save the file.
you have to first check whether file exists or not?
using FileInfo,
FileInfo file = new FileInfo(location);
if(file.Exists())
{
File.Delete(location);
File.Copy(srcLocation, location);
}
In this way you can avoid the error.
