How to use

Output formatters

Starting from a Program.cs or a similar entry point file in your MVC project, add the following code.

// Entry point
var builder = WebApplication.CreateBuilder(new WebApplicationOptions
{
   // ...
});

// ...

builder.Services
    .AddControllers()
    // Adds csv output formatter
    .AddCsvOutputFormatter(options =>
    {
        options.Delimiter = ','; // The values delimiter or separator
        options.UseHeader = true; // A flag indicating whether the comma separated values should include a header (line) or not
        options.Encoding = System.Text.Encoding.UTF8.WebName; // Encoding
    })
    // Adds csv output formatter
    .AddPdfOutputFormatter();

// ...

The extension methods AddCsvOutputFormatter and AddPdfOutputFormatter handle the configuration to enable any endpoint to support returning data not only in the default JSON format but also in CSV or PDF formats.

curl --location 'https://my-endpoint.net/controller' \
--header 'Accept: text/csv'
# Response: 200 OK with CSV data

curl --location 'https://my-endpoint.net/controller' \
--header 'Accept: application/pdf'
# Response: 200 OK with PDF data

Input formatters

Starting from a Program.cs or a similar entry point file in your MVC project, add the following code.

// Entry point
var builder = WebApplication.CreateBuilder(new WebApplicationOptions
{
   // ...
});

// ...

builder.Services
    .AddControllers()
    // Adds csv output formatter
    .AddCsvInputFormatter(options =>
    {
        options.Delimiter = ','; // The values delimiter or separator
        options.UseHeader = true; // A flag indicating whether the comma separated values should include a header (line) or not
        options.Encoding = System.Text.Encoding.UTF8.WebName; // Encoding
    });

// ...

The extension method AddCsvInputFormatter is responsible for configuring everything necessary to enable any endpoint to support receiving information through the body in CSV format.

curl --location 'https://localhost:7184/weatherforecast' \
--header 'Content-Type: text/csv' \
--data 'Foo,Bar
Foo Value,100
Other foo Value, 150'
# Response: 200 OK
