## How to Use
### Extension Method
Install the `DMime` package:
```
dotnet add package Dmime
```
Then use the `DetectMimeTypeAsync` or `DetectMimeType` extension methods on any `Stream` type.
```c#
// an unkown file without extension
FileStream stream = File.OpenRead("webp-sample-550w-404h");
var result = await stream.DetectMimeTypeAsync(); // result = image/webp
```
### Dependency
Install the `Dmime.Extensions.MicrosoftDependencyInjection` package:
```
dotnet add package Dmime.Extensions.MicrosoftDependencyInjection
```
Register the dependency into ASP.NET Core DI container:
```c#
services.AddMimeDetector();
```
Then inject the `IMimeDetector` to your desired class and use the `DetectAsync` or `Detect` methods accordingly.
```c#
[ApiController]
[Route("[controller]")]
public class UploadController
{
private readonly IMimeDetector _mimeDetector;
public UploadController(IMimeDetector mimeDetector)
{
_mimeDetector = mimeDetector;
}
[HttpPost]
public async Task SendNotification(IFormFile formFile)
{
var streamContent = formFile.OpenReadStream();
var result = await _mimeDetector.DetectMimeTypeAsync(streamContent);
return Ok(result);
}
}
```
