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 particular value    I am using C  and was using FileInfo class  While it does have CopyTo method  It does not give me the option to set the file name  And the MoveTo method while allowing me to rename the file  deletes the file in the original location   What is the best way to go about this

The easiest method you can use is this   System IO File Replace string sourceFileName  string destinationFileName  string destinationBackupFileName     This will take care of everything you requested

File Copy   C  oldFile txt     C  newFile txt   true     Please do not forget to overwrite the previous file  Make sure you add the third param   by adding the third param  you allow the file to be overwritten  Else you could use a try catch for the exception   Regards  G

One method is   File Copy oldFilePathWithFileName  newFilePathWithFileName     Or you can use the FileInfo CopyTo   method too something like this   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

You can use either File Copy oldFilePath  newFilePath  method or other way is  read file using StreamReader into an string and then use StreamWriter to write the file to destination location   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
