copy a csv file in csharp

To copy a CSV file in C#, you can use the File.Copy method from the System.IO namespace:

main.cs
using System.IO;

string sourceFilePath = "path/to/source.csv";
string destinationFilePath = "path/to/destination.csv";

File.Copy(sourceFilePath, destinationFilePath);
169 chars
7 lines

In the above code, sourceFilePath is the path of the CSV file that you want to copy and destinationFilePath is the path of the new copy of the file. The File.Copy method creates a new file at the destination path with the same content as the source file.
