Write a Stream to a File in C#
This tutorial will discuss the method to write a stream to a file in C#.
Write Stream to a File With the Stream.CopyTo() Method in C
The Stream.CopyTo() method in C# copies the contents of a stream to another stream. We can open a file in the second stream and copy the input stream’s content to the output stream with the Stream.CopyTo() method in C#.
using System;
using System.IO;
namespace read_integer
{
class Program
{
static void Main(string[] args)
{
using(Stream inStream = File.OpenRead(@"C:\File\file.txt"))
{
using(Stream outStream = File.OpenWrite(@"C:\File\file1.txt"))
{
inStream.CopyTo(outStream);
}
}
}
}
}
In the above code, we write the contents of our input stream inStream to our output stream outStream with the inStream.CopyTo(outStream) method in C#. We first open our input file file.txt inside the path C:\File to read data to the inStream stream. After that, we open our output file file1.txt inside the same directory C:\File to write with the outStream stream. We then write the contents of the inStream to the outStream with the Stream.CopyTo() method.
