C # Copy a file to another location with a different name

Question

If certain conditions are met, I want to copy a file from one directory to another WITHOUT deleting the original file. I also want to set the name of the new file to a specific value.

I use C # and use the FileInfo class. Although it does have a CopyTo method. This prevents me from setting the file name. And the MoveTo method, letting me rename the file, deletes the file at its original location.

What is the best way to do this?

Answer 1

System.IO.File.Copy(oldPathAndName, newPathAndName); 

Answer 2

You can also try Copy :

 File.Copy(@"c:\work\foo.txt", @"c:\data\bar.txt") 

Answer 3

Use File.Copy instead

eg.

 File.Copy(@"C:\oldFile.txt", @"C:\newFile.txt"); 

You can call it whatever you want in newFile, and it will rename it accordingly.

Answer 4

If you want to use only the FileInfo class try this

  string oldPath = @"C:\MyFolder\Myfile.xyz"; string newpath = @"C:\NewFolder\"; string newFileName = "new file name"; FileInfo f1 = new FileInfo(oldPath); if(f1.Exists) { if(!Directory.Exists(newpath)) { Directory.CreateDirectory(newpath); } f1.CopyTo(string.Format("{0}{1}{2}", newpath, newFileName, f1.Extension)); } 

Answer 5

One of the methods:

 File.Copy(oldFilePathWithFileName, newFilePathWithFileName); 

Or you can use the FileInfo.CopyTo () method, for example:

 FileInfo file = new FileInfo(oldFilePathWithFileName); file.CopyTo(newFilePathWithFileName); 

Example:

 File.Copy(@"c:\a.txt", @"c:\b.txt"); 

or

 FileInfo file = new FileInfo(@"c:\a.txt"); file.CopyTo(@"c:\b.txt"); 

Answer 6

 StreamReader reader = new StreamReader(Oldfilepath); string fileContent = reader.ReadToEnd(); StreamWriter writer = new StreamWriter(NewFilePath); writer.Write(fileContent); 

Answer 7

 File.Copy(@"C:\oldFile.txt", @"C:\newFile.txt", true); 

Please do not forget to overwrite the previous file! Make sure you add the third parameter. By adding a third parameter, you allow overwriting the file. Alternatively, you can use try catch for an exception.

Answer 8

You can use the Copy method in the System.IO.File class.

Answer 9

The easiest way you can use is this:

 System.IO.File.Replace(string sourceFileName, string destinationFileName, string destinationBackupFileName); 

This will take care of everything you requested.

Answer 10

You can use the File.Copy method (oldFilePath, newFilePath) or in another way, read the file using StreamReader into a string, and then use StreamWriter to write the file to the destination.

Your code might look like this:

 StreamReader reader = new StreamReader("C:\foo.txt"); string fileContent = reader.ReadToEnd(); StreamWriter writer = new StreamWriter("D:\bar.txt"); writer.Write(fileContent); 

You can add exception handling code ...
