如何将文本或二进制数据传递到ASP.NET Core Razor pages项目中的浏览器

public class MyPageModel : PageModel
{
    public async Task<IActionResult> OnGet()
    {
        string textData = "Hello, World!";

        // 将文本数据写入响应流
        await HttpContext.Response.WriteAsync(textData);

        return new EmptyResult();
    }
}

public class MyPageModel : PageModel
{
    public async Task<IActionResult> OnGet()
    {
        byte[] binaryData = GetBinaryData();

        // 将二进制数据写入响应流
        await HttpContext.Response.Body.WriteAsync(binaryData, 0, binaryData.Length);

        return new EmptyResult();
    }

    private byte[] GetBinaryData()
    {
        // 从某个地方获取二进制数据
        // 例如，从文件读取、从数据库查询等

        return new byte[] { 0x01, 0x02, 0x03 };
    }
}
