|
|
Constants for (almost) all MIME types and method to determine MIME type from a file name.
|
|
Contains just over 1000 mime types.
|
|
|
|
The Dictionary is generated from the [`jshttp/mime-db`](https://github.com/jshttp/mime-db#mime-db) `db.json`.
|
|
Works similar to .NET's [System.Web.MimeMapping.GetMimeMapping](https://learn.microsoft.com/dotnet/api/system.web.mimemapping.getmimemapping).
|
|
|
|
It aggregates data from the following sources:
|
|
|
|
- <https://www.iana.org/assignments/media-types/media-types.xhtml>
|
|
- <https://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types>
|
|
- <https://hg.nginx.org/nginx/raw-file/default/conf/mime.types>
|
|
|
|
The library is just a literal C# `Dictionary<string, string>` with over 1000 entries, and a helper method that can be passed a file path.
|
|
|
|
## Example Usage
|
|
|
|
```C#
|
|
string myFile = "myimage.jpg";
|
|
string mimeType = MimeMapping.MimeUtility.GetMimeMapping(myFile);
|
|
Console.WriteLine(mimeType); // output: image/jpeg
|
|
|
|
string randomFile = "data.asdf";
|
|
string mimeType = MimeMapping.MimeUtility.GetMimeMapping(randomFile);
|
|
Console.WriteLine(mimeType); // output: application/octet-stream
|
|
|
|
string rawExtension = "json";
|
|
string mimeType = MimeMapping.MimeUtility.GetMimeMapping(rawExtension);
|
|
Console.WriteLine(mimeType); // output: application/json
|
|
|
|
|
|
// List all types..
|
|
foreach(var kp in MimeMapping.MimeTypes.TypeMap)
|
|
{
|
|
Console.WriteLine($"File extension: {kp.Key}, mime string: {kp.Value}");
|
|
}
|
|
```
