C# Rename File Add

As a programmer, file management is a crucial aspect of your work. In C#, renaming a file is a common requirement. Additionally, adding a file to a directory is also a frequent task. In this article, we will learn how to rename a file and add a file using C#.

Renaming a File

To rename a file in C#, we need to use the System.IO.File class. The File class provides various static methods to manipulate files. To rename a file, we can call the File.Move() method and pass the old file path and the new file path as arguments.

string oldFilePath = @"C:\oldFile.txt";
string newFilePath = @"C:\newFile.txt";
File.Move(oldFilePath, newFilePath);

The above code will rename the oldFile.txt file to newFile.txt.

Adding a File

To add a file to a directory, we can use the File.Copy() method provided by the System.IO.File class. This method creates a copy of the file at the specified path.

string sourceFilePath = @"C:\sourceFile.txt";
string destinationDirectoryPath = @"C:\DestinationFolder";
string destinationFilePath = Path.Combine(destinationDirectoryPath, Path.GetFileName(sourceFilePath));

File.Copy(sourceFilePath, destinationFilePath);

The above code will copy the sourceFile.txt file to the DestinationFolder. The Path.Combine() method is used to combine the destination directory path with the file name.
