File Upload

Radzen.Blazor Components
1

Code previously used in .net 5.0.

<BlazorFileUploader.InputFile OnChange="HandleFileSelected" />

public async Task HandleFileSelected(IFileListEntry[] files)
{
    if (files.Count() > 0)
    {
        file = files.FirstOrDefault();
        using (var ms = new MemoryStream())
        {
            await file.Data.CopyToAsync(ms);
            _fileBytes = ms.ToArray();

            fileModelToInsert.FileNm = file.Name;
            fileModelToInsert.FileType = file.Type;
            await jsRuntime.InvokeVoidAsync("alert", "confirm.");
            fileModelToInsert.FileData = Convert.ToBase64String(_fileBytes);
        }
    }
}

I wrote it using the BlazorFileUploader package. Upgrade it to .net 8.0, Blazor Upload Component | Free UI Components by Radzen

I referred to this site. The question here is that FileName can be imported, but I tried to convert the file extension and most important file information into bytes and then convert it into convert64string, but I don't know where the file data is.

RadzenUpload works in different way - will post the file to a controller where you can read it. Check our demos for reference:
