How to Create MIME Types Custom Class in C#
This post explains, how to create a custom class and methods to get MIME type by file name or extension and vice-versa. MediaTypeNames class is also available that exists in System.Net.Mime namespace but the listed mime types or extensions are very limited. But I have mentioned more than 1300 MIME Types in the mapping list.
Steps to Create Mime Type Custom Class
- Create a Static class called MimeType (.cs file)
- give a unique name for the namespace as well.
- declare a read-only dictionary field that contains the list of all MIME types.
- Create two public static methods:
- 1) GetMimeType(): to get MIME type by file name or extension
- 2) GetExtension(): to get file extension by mime type
Mime Type Class – full C# code
Simply copy & paste the entire code in MimeType.cs file, given below.
code usage & output – example
Full code
namespace Utility
{
public static class MimeType
{
private const string Dot = ".";
private static readonly Lazy<IDictionary<string, string>> _mappings = new Lazy<IDictionary<string, string>>
(() => new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase)
