To delete a file in C#, use the File.Delete() method from the System.IO namespace.

Syntax:

File.Delete(string path);

path: The full path of the file to delete.

Example:

using System.IO;

string filePath = @"C:\example\myfile.txt";

if (File.Exists(filePath))
{
    File.Delete(filePath);
    Console.WriteLine("File deleted.");
}
else
{
    Console.WriteLine("File not found.");
}

Notes:

  1. No exception is thrown if the file doesn’t exist — unless you try to access it afterward.
  2. Will throw exceptions like:
    1. UnauthorizedAccessException: If you don't have permission.
    2. IOException: If the file is in use by another process.
    3. ArgumentException / PathTooLongException: If the path is invalid.

Optional: Safe delete with try-catch

try
{
    if (File.Exists(filePath))
        File.Delete(filePath);
}
catch (Exception ex)
{
    Console.WriteLine("Error deleting file: " + ex.Message);
}
