In this tutorial, we'll learn how to create a new text file with a specific path using C#. We'll use the StreamWriter class to write text to the file, and we'll get the text to write from a textbox on a form.

Here's the sample code we'll be using:


using System.IO;

// Assuming you have a textbox named textBox1 on your form

// Specify the path and filename of the new text file
string filePath = @"C:\Example\NewFile.txt";

// Get the text from the textbox
string textToWrite = textBox1.Text;

// Create the file if it doesn't exist, or overwrite it if it does
using (StreamWriter writer = new StreamWriter(filePath, false))
{
// Write the text to the file
writer.Write(textToWrite);
}
This code creates a StreamWriter object that writes to the file specified by filePath. The false parameter in the StreamWriter constructor specifies that the file should be overwritten if it already exists, rather than appended to. The using statement ensures that the StreamWriter object is properly disposed of after use.
