Missing.Extensions.Stream

NuGet Version NuGet Downloads

Detects media type (MIME type) for System.IO.Stream by checking its signature.

Why is it useful?

  • Security: Prevents spoofing by validating files based on content, not just extension.
  • Performance optimized: Minimal allocations, thread safety, and high efficiency.
  • No external dependencies: Pure .NET, no third-party libraries required.

Example usage

using Missing.Extensions.Stream;

var (name, ext) = File
    .OpenRead("open.me")
    .GetMediaType();

Console.WriteLine($"{name}, {ext}");
// Outputs: application/pdf, pdf
