Introduction

ASP.NET is a popular programming language used for developing web . One common requirement in web applications is the ability to download to the user's local computer. In this article, we will explore how to download an Excel package file in an ASP.NET MVC application.

Step 1: Create a Controller Action

To begin, we need to create a controller action that will the file download . In your ASP.NET MVC application, open the desired controller and add a new action method. This method will be responsible for generating and returning the Excel file to the user.


 ActionResult DownloadExcelFile()
{
    //  the Excel file
    var excelPackage = new ExcelPackage();
    // Add data and formatting to the Excel package

    // Set the file name and content type
    var fileName = "example.xlsx";
    var contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

    // Convert the Excel package to a byte 
    byte[] fileBytes = excelPackage.GetAsByteArray();

    // Return the file as a FileResult
    return File(fileBytes, contentType, fileName);
}

Step 2: Create a Download Link

Next, we need to create a download link in our view to trigger the file download. Open the desired view file and add the following HTML code:


@Html.ActionLink("Download Excel File", "DownloadExcelFile", "ControllerName")

Replace “ControllerName” with the actual name of your controller.

Step 3: Test the File Download
