using System.IO; string filePath = "C:\\Users\\Username\\Desktop\\example.txt"; string newContent = "This is some new content that will replace the old content in the file."; using (StreamWriter writer = new StreamWriter(filePath)) { writer.Write(newContent); } Console.WriteLine("The file has been updated successfully.");In this example, the ActualizarArchivo variable is represented by the StreamWriter object that is used to write new content to the file. The file path is specified in the filePath variable, and the new content is stored in the newContent variable. The StreamWriter is then used to write the new content to the file, effectively updating it.
