Learn how to create 7z archive in C# with this straightforward guide. Follow step‑by‑step instructions and a ready‑to‑use code sample that demonstrate how a C# 7z file can be generated directly within your applications—no third‑party tools or external compression software needed.

Steps to Create 7z Archive in C#

1. Install Conholdate.Total for .NET from the NuGet package manager to create 7z archive
2. Initialize a SevenZipArchive class object
3. Add all files and directories using the CreateEntries method
4. Save the output archive as a 7z file

We can clearly understand the process to create a 7z archive through this step-by-step approach. The above steps also cover the configuration details and then provide the C# 7zip example code to create the archive. You can compress a single file by specifying its name or compress a whole folder by using its path.

Code to Create 7z Archive in C#

To create a 7z C# archive, this guide outlines the required environment and provides ready‑to‑run sample code. By supplying a folder path, the code compresses every item in that directory into a single 7‑zip archive. You can further enhance the snippet with AES encryption and password protection to secure the resulting file. For maximum scalability, embed the logic in a thread‑based application to exploit parallel‑processing benefits.

In this guide we’ve explored how to work with a 7zip‑based C# application to create archives. If you’d like to learn how to extract files from a ZIP archive as well, be sure to read our article on how to extract ZIP file in C#.
