是否在C# WEB API自定义AuthorizeAttribute中阻止凭据提示？

public class CustomAuthorizeAttribute : AuthorizeAttribute
{
    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        // 在这里进行自定义的授权逻辑判断
        // 如果不满足授权条件，返回false
        // 如果满足授权条件，返回true

        // 示例：阻止凭据提示
        if (!IsAuthorized(httpContext))
        {
            httpContext.Response.SuppressFormsAuthenticationRedirect = true;
            httpContext.Response.StatusCode = 401;
            httpContext.Response.End();
            return false;
        }

        return true;
    }
}

[CustomAuthorize]
public class MyController : ApiController
{
    // ...
}
