How do you copy a file from one location to another in C#?

Question

Anubhav Kumar · Answer

In C#, you can copy a file from one location to another using the File.Copy method from the
System.IO namespace.
Syntax:
File.Copy(string sourceFileName, string destFileName, bool overwrite);
sourceFileName: Full path to the file you want to copy.destFileName: Full path where you want the file copied.overwrite (optional): Set to true if you want to overwrite the destination file if it exists.
Example 1: Copy without overwrite
using System.IO;
File.Copy(@"C:\source\file.txt", @"C:\destination\file.txt");
This throws an exception if the destination file already exists.
Example 2: Copy with overwrite
File.Copy(@"C:\source\file.txt", @"C:\destination\file.txt", true);
This replaces the destination file if it already exists.
Exceptions to handle (optionally):
FileNotFoundException: If the source file doesn't exist.IOException: If the destination file exists and overwrite is
false.UnauthorizedAccessException: If access is denied (e.g., permissions).DirectoryNotFoundException: If the path is invalid.
