using  System.IO.Compression;

public class CompressAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {

        var encodingsAccepted = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
        if (string.IsNullOrEmpty(encodingsAccepted)) return;

        encodingsAccepted = encodingsAccepted.ToLowerInvariant();
        var response = filterContext.HttpContext.Response;

        if (encodingsAccepted.Contains("deflate"))
        {
            response.AppendHeader("Content-encoding","deflate");
            response.Filter = new DeflateStream(response.Filter,CompressionMode.Compress);
        }
        else if (encodingsAccepted.Contains("gzip"))
        {
            response.AppendHeader("Content-encoding","gzip");
            response.Filter = new GZipStream(response.Filter,CompressionMode.Compress);
        }
    }
}

在控制器中的使用：

[Compress]
public class BookingController : BaseController
{...}

还有其他varients，但这工作相当不错。 (btw，我使用我的BaseController上的[Compress]属性来保存项目中的重复，而上面是在控制器基于控制器。

[编辑]。为了简化使用，您还可以在BaseController本身中包括[Compress] oneshot，从而，每个继承的子控制器默认访问该功能：

[Compress]
public class BaseController : Controller
{...}
