BlazorBlobStream

A seekable File stream for Blazor.

Nuget (with prereleases) GitHub license

This is an alternative implementation of Microsoft.AspNetCore.Components.Forms.IBrowserFile. The stream returned by OpenReadStream now supports setting the Position property and calling the Seek method.

Why

The MS provided implementation of IBrowserFile returns a stream that doesn't allow seeking. If you need to seek in this stream, you are left with the only option of copying the whole stream into the memory.

How

All browsers support seeking in Files by slicing the Blob. This implementation uses blob-slicing to support seeking in Blazor.

Usage

To get seekable file streams, you just have to:

  1. Install this NuGet package:
dotnet add package BlazorBlobStream
  1. Register the BlobStreamService in Program.cs:
using BlazorBlobStream;
...
builder.Services.AddTransient<BlobStreamService>();
  1. Inject and call the BlobStreamService in razor page:
@inject BlazorBlobStream.BlobStreamService BlobStreamService

<InputFile @ref="inputFile" OnChange="OnFileChange"/>

@code {
    InputFile inputFile = default!;

    async Task OnFileChange(InputFileChangeEventArgs fileChange)
    {
        var browserFiles = await BlobStreamService.GetBrowserFilesAsync(inputFile);
        var browserFile = browserFiles.First();
        await using var fileStream = browserFile.OpenReadStream(maxAllowedSize: browserFile.Size);
    }
}
  1. Seek freely!
