Comment lire un fichier Excel dans Blazor NET

In this tutorial, you will learn how to view Excel files within a Blazor Server application by setting up an Excel file viewer using IronXL. The process involves integrating IronXL into a Visual Studio project and working with the necessary code.

First, import the required using statements for IronXL and System.Data. Define a table structure in HTML with dynamic headers based on the Excel file's columns, while the rows are filled with data from the file.

In the @code section, a data table named displayDataTable is declared to store Excel data. The OpenExcelFromDisk method manages file uploads and data extraction. When an Excel file is uploaded, it is read into a memory stream, which IronXL loads into a workbook object. The first row's headers become the data table's columns, and subsequent rows are added as data rows.

Running the code opens a Blazor web application page where you can navigate to the 'fetch data' menu, open an Excel file, and view its contents. This tutorial demonstrates the simplicity of using IronXL to create an Excel file viewer in a Blazor server app, enhancing web application capabilities.
