C# – First steps with C# and .NET – part 043. – free-tutorials.org news free tutorials source code development scripts

In this tutorial, I will show you a C # source code that he uses FileStream and StreamWriter to write to the file.
A Stream for a file, supporting both synchronous and asynchronous read and write operations.
A TextWriter is used for writing characters to a stream in a particular encoding.
The result is a text file with the contents: This is a line of text.
The following lines will be displayed in the program console:

Hello World!
Writer and file is close !

1 2	Hello World! Writer and file is close !

If you want to use encoding then you will have to add and modify with this source code in C#.

using System.Text;
...
writer = new StreamWriter(fileStream, Encoding.UTF8);

using System.Text;

...

writer = new StreamWriter(fileStream, Encoding.UTF8);

Let’s see the source code:

using System;
using System.IO;

namespace FileStreamStreamWriter
{
	class Program
	{
		public static void Main(string[] args)
		{
			Console.WriteLine("Hello World!");
			FileStream fileStream;
			StreamWriter writer;
			TextWriter outputTextWriter = Console.Out;
			try
			{
				fileStream = new FileStream("stream.txt", FileMode.OpenOrCreate, FileAccess.Write);
				writer = new StreamWriter(fileStream);
			}
			catch (Exception e)
			{
				Console.WriteLine("Cannot open stream.txt for writing");
				Console.WriteLine(e.Message);
				return;
			}
			Console.SetOut(writer);
			Console.WriteLine("This is a line of text");
			Console.SetOut(outputTextWriter);
			writer.Close();
			fileStream.Close();
			Console.WriteLine("Writer and file is close !");
		}
	}
}

using System;

using System.IO;

namespace FileStreamStreamWriter

{

class Program

{

public static void Main(string[] args)

{

Console.WriteLine("Hello World!");

FileStream fileStream;

StreamWriter writer;

TextWriter outputTextWriter = Console.Out;

try

{

fileStream = new FileStream("stream.txt", FileMode.OpenOrCreate, FileAccess.Write);

writer = new StreamWriter(fileStream);

}

catch (Exception e)

{

Console.WriteLine("Cannot open stream.txt for writing");

Console.WriteLine(e.Message);

return;

}

Console.SetOut(writer);

Console.WriteLine("This is a line of text");

Console.SetOut(outputTextWriter);

writer.Close();

fileStream.Close();

Console.WriteLine("Writer and file is close !");

}
