如何在Blazor服务器端下载文件？

<a href="download">下载文件</a>

<a href="download" @onclick="DownloadFile">下载文件</a>

@code {
    private async Task DownloadFile()
    {
        // 执行文件下载的逻辑
    }
}

private async Task DownloadFile()
{
    // 读取文件内容
    byte[] fileBytes = await File.ReadAllBytesAsync("path/to/file");

    // 设置响应头，指定文件名和文件类型
    string fileName = "example.txt";
    string contentType = "text/plain";
    HttpContext.Response.Headers.Add("Content-Disposition", $"attachment; filename={fileName}");
    HttpContext.Response.ContentType = contentType;

    // 将文件内容写入响应流
    await HttpContext.Response.Body.WriteAsync(fileBytes, 0, fileBytes.Length);
}
