有没有办法让文件流下载到Blazor中的浏览器？

[HttpGet]
public IActionResult DownloadFile()
{
    // 从文件系统或其他来源获取文件流
    Stream fileStream = GetFileStream();

    // 设置文件下载的名称
    string fileName = "example.txt";

    // 返回FileStreamResult
    return new FileStreamResult(fileStream, "application/octet-stream")
    {
        FileDownloadName = fileName
    };
}

@inject HttpClient httpClient

<button @onclick="DownloadFile">下载文件</button>

@code {
    private async Task DownloadFile()
    {
        // 调用控制器方法并获取文件流
        var response = await httpClient.GetAsync("/api/DownloadFile");
        response.EnsureSuccessStatusCode();

        // 读取文件流并下载文件
        var fileStream = await response.Content.ReadAsStreamAsync();
        await JSRuntime.InvokeVoidAsync("saveAsFile", "example.txt", fileStream);
    }
}

window.saveAsFile = (filename, byteBase64) => {
    const blob = base64ToBlob(byteBase64);
    const link = document.createElement('a');
    link.href = URL.createObjectURL(blob);
    link.download = filename;
    link.click();
}

function base64ToBlob(base64) {
    const byteCharacters = atob(base64);
    const byteNumbers = new Array(byteCharacters.length);
    for (let i = 0; i < byteCharacters.length; i++) {
        byteNumbers[i] = byteCharacters.charCodeAt(i);
    }
    const byteArray = new Uint8Array(byteNumbers);
    return new Blob([byteArray], { type: 'application/octet-stream' });
}
