How to Extract RAR Files using C#

In this guide, we will cover the process of how to extract RAR files using C#. It has the resources to set the development environment, a list of steps that elaborates the programming logic, and a runnable sample code to unzip RAR files using C#. You will learn the options to extract the selected files only based on different criteria.

Steps to Unpack RAR Files using C#

  1. Set the environment to use Aspose.Zip for .NET to extract RAR files
  2. Load the source RAR file using the RarArchive class object
  3. Parse through all the entries in the RAR file
  4. Create a file stream using the entry name in each iteration
  5. Read all the bytes from the source entry and save them in the file stream
  6. Save each file on the disk after writing all the bytes

These steps elaborate on how to extract RAR using C#. The process is commenced by loading the source RAR file followed by parsing through all the entries in it. Create a separate file for each entry using its name and save all the bytes from the archive into the respective file before saving it on the disk.

Code to Extract RAR Files using C#

using System;
using System.IO;
using Aspose.Zip;
using Aspose.Zip.Rar;
class Program
{
static void Main(string[] args) // Extract RAR
{
// Set the license
new License().SetLicense("Aspose.Total.Product.Family.lic");
// LLoad the RAR file
using (RarArchive rarArchive = new RarArchive("Sample.rar"))
{
// Parse all the entries in the archive
foreach(var entry in rarArchive.Entries)
{
// Create a file
var file = File.Create(entry.Name);
// Open the archive and save data to the file
using (var fileEntry = entry.Open())
{
byte[] data = new byte[1024];
int bytesCount;
while ((bytesCount = fileEntry.Read(data, 0, data.Length)) > 0)
file.Write(data, 0, bytesCount);
// Close the file
file.Close();
file.Dispose();
}
}
}
Console.WriteLine("Done");
}
}

This sample code reveals how to unzip RAR using C#. While iterating through all the entries in the archive, you may filter the files using the compressed size, creation time, last access time, modification time, and name as used in the sample code. It is not necessary to extract the files, as you may only get the file info using the RarArchiveEntry class.
