In the following example, we use the WriteAllText() method to create a file named "filename.txt" and write some content to it. Then we use the ReadAllText() method to read the contents of the file:

using System.IO; // include the System.IO namespace
string writeText = "Hello World!"; // Create a text string
File.WriteAllText("filename.txt", writeText); // Create a file and write the content of writeText to it
string readText = File.ReadAllText("filename.txt"); // Read the contents of the file
Console.WriteLine(readText); // Output the content
