Provides a huge two-way mapping of file extensions to mime types and mime types to file extensions, e.g.:

{".jpeg", "image/jpeg"},
{".jpg", "image/jpeg"},
{".js", "application/javascript"},
{".json", "application/json"},
...

Note

There is a little different behavior between samuelneff version.

In my experience, one extension sometimes will have different mime type depend on various browser.

This package will return all match mime.

For example: .mp3 and zip will have multi mime type depend on various browser, see: https://stackoverflow.com/a/28021591/1799047 , .zip will have three mime type: application/zip, application/octet-stream, application/x-zip-compressed

Installation

A NuGet package is available for easy integration into VisualStudio and automatic updates. Alternatively, you can clone and reference or copy the class to your project.

Install-Package MimeTypeMap.List

Support Platform

Support .NET 4.5 above or .NET Standard 1.0 above

Usage

After installation MimeTypeMap.List, include the following using statement in your class:

using MimeTypeMap.List;

Getting the mime type to an extension

Console.WriteLine("txt -> " + MimeTypeMap.GetMimeType("txt"));  // "text/plain"

Pass in a string extension and get a mime type back. Optionally include the period. If not it will be added before looking up the mime type.

If no mime type is found then the generic "application/octet-stream" is returned.

Getting the extension to a mime type

Console.WriteLine("audio/wav -> " + MimeTypeMap.GetExtension("audio/wav")); // ".wav, .wave"

Pass in a mime type and get an extension back. If the mime type is not registered, an error is thrown.
