🤔 Have you ever faced the challenge of sending a CSV file in an HTTP response? Are you scratching your head trying to figure out how to set the output response as CSV format? Don't worry, we've got you covered! In this blog post, we'll address the common issues around this question and provide easy solutions to help you achieve your goal. So, let's dive right in!

❌ The Misconception

One common misconception is that setting the Response.ContentType as "application/CSV" would do the job. However, unfortunately, that's not the correct approach. Don't worry, you're not alone in making this mistake.

🔍 The Right Solution

To set the output response as CSV format, you need to use a correct content type. In this case, the appropriate content type for CSV files in HTTP responses is "text/csv".

💡 Here's the Correct Approach:

Response.ContentType = "text/csv";

✔️ Example: Sending a CSV File in the HTTP Response

Let's consider an example scenario where you want to send a CSV file named employees.csv in the HTTP response. Here's how you can achieve that using the correct content type:

public IActionResult DownloadCSV()
{
    // Retrieve the CSV data or generate it dynamically
    string csvData = "Name,Email\nJohn Doe,johndoe@example.com\nJane Smith,janesmith@example.com";

    // Set the output response as CSV format
    Response.ContentType = "text/csv";

    // Set a meaningful file name for the download
    Response.Headers.Add("Content-Disposition", "attachment; filename=employees.csv");

    // Write the CSV data to the response body
    Response.Body.Write(Encoding.ASCII.GetBytes(csvData));

    return new EmptyResult(); // Or you can return a view or redirect as per your requirement
}

By following this approach, you will be able to send the CSV file in the HTTP response successfully.
