How to create a file .txt with C#

Its very easy creates a file .txt using Visual C#, in order to use the normal references like:

using System.Text;
using System.IO;

Let’s begin:

private void create_file()
{

string fileName = Application.StartupPath.Substring(0, 2) + "\\My File.txt";
//A string with the drive where our application is running

//(in my own, the drive C:) and the name of the file .txt

//(check thats necessary the double '\\')

StreamWriter writer = File.CreateText(fileName);

//Lets use the StreamWriter whos going to help us to write in the file .txt

//and is equal to the object File and the method CreateText with

//the name of our file....the string fileName

writer.WriteLine(""Greetings from Poza Rica, Ver., Mexico");
//With writer we may write a line in the file

writer.WriteLine("");

//I use this to create a line blank

writer.WriteLine("Im Dr. Omm");
writer.WriteLine("");
writer.Close();

//Finally, we close the writer

}

I hope this be hepful to somebody...and sorry by my english

Dr. Omm
