How to write a new line to a txt file in C#?

To write to a txt file and add a new line in C#, you can use the WriteLine method of the StreamWriter class. Here is an example code:

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string filePath = @"C:\example.txt";
        
        using (StreamWriter writer = new StreamWriter(filePath))
        {
            writer.WriteLine("First line");
            writer.WriteLine("Second line");
            writer.WriteLine("Third line");
        }
        
        Console.WriteLine("Text written to file.");
    }
}

In the example above, a StreamWriter object is first created with the specified file path. Then, the WriteLine method is used to write each line of text, automatically adding a newline at the end of each line. Finally, the StreamWriter object is released.
