Comment définir un mot de passe sur une feuille Excel en C#

In this tutorial, we explore the process of password protecting Excel worksheets using the IronXL library in C#. The video begins by guiding viewers to install the IronXL namespace via the Noug Get package manager. Once installed, the tutorial demonstrates how to load an existing workbook from the C drive using the workbook load function. The focus then shifts to applying protection on a selected worksheet with the 'protect sheet' method, using 'iron XL' as the password. After setting the protection, the workbook is saved to apply changes. An interesting feature highlighted in the tutorial is the ability to unprotect the worksheet programmatically without entering the password by uncommenting a specific line of code. The video concludes with a demonstration of the project in action, where the Excel file is opened, and the protection is validated by entering the password. This tutorial provides a comprehensive guide for developers looking to secure their Excel data programmatically, offering a practical demonstration of IronXL's capabilities.
