Download file download

For direct download of physical files

Razor code
<Button OnClick="DownloadFile">Click me to download the file</Button>
C# code
private async Task DownloadFileAsync()
    using var stream = await GenerateFileAsync();
    await DownloadService.DownloadFromStreamAsync("test file", stream);

    static async Task<Stream> GenerateFileAsync()
        var ms = new MemoryStream();
        var writer = new StreamWriter(ms);
        await writer.WriteLineAsync("Self-generated and written text, here can be replaced with pictures or other content");
        await writer.FlushAsync();
        ms.Position = 0;
        return ms;

Download files directly by setting the physical path


By setting the physical path of the folder, the files in the directory are packaged and compressed and downloaded


This simulation generates a text file of 1 million lines, about 58M, which can be tested by yourself


The button sets the value of IsAsync to true for asynchronous download operation

Simulate the situation where the verification code is generated directly from the front-end page or the uploaded image is not saved and displayed directly.


Since the test uses the files under wwwroot, there is no code generation, and wasm cannot access the wwwroot folder, so only the ssr mode is available for the test. wasm please test it yourself.

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
