How to Rename Files in C# Using `File.Move()`?

Rename files using C#

C#'s System.IO.File class provides a variety of file manipulation methods, including renaming files. You can use the File.Move() method to rename files. This method actually moves the file to a new name, thus achieving the effect of renaming.

The

File.Move() method accepts two parameters:

• sourceFileName: The original name of the file to be renamed.
• destFileName: The new name to be given to the file.

The following example demonstrates how to use the File.Move() method to rename a file:

<code class="language-csharp">using System.IO;

namespace 文件重命名
{
    class Program
    {
        static void Main(string[] args)
        {
            // 指定现有文件名
            string 旧文件名 = "oldfilename.txt";

            // 指定新文件名
            string 新文件名 = "newfilename.txt";

            // 重命名文件
            System.IO.File.Move(旧文件名, 新文件名);

            Console.WriteLine("文件重命名成功。");
        }
    }
}</code>

Running this code will rename the file "oldfilename.txt" to "newfilename.txt". Note that the File.Move() method actually moves the file to a new name rather than creating a copy under that name.
