Question

我正在使用静态方法创建静态类，以帮助控制器完成工作。构建应用程序时，我收到以下错误：

错误40＆＃39; System.Web.Mvc.Controller.Content(string)＆＃39;由于其保护级别而无法访问＆＃34;

知道如何解决这个问题吗？

注意：它是一个c＃mvc aplication

public static ActionResult GetAlbumJSON(AlbumVO album)
{
    return Controller.Content(
        JsonConvert.SerializeObject(new
        {
            max_car = @ABookClient.maxCharsProjecName,
            trans_img = @ABookClient.Transparent_Image,
            show_description = @ABookClient.Show_Product_Description,
            product_type = "Album",
            obj = CreateObjAlbumVO(album),
        })
    );
}

Answer 1

内容方法受内部保护，因此您无法在控制器之外使用它。 Controller.Content Method。很可能你的静态类违反了SRP原则。让他完成他的工作（初始化，序列化......）和控制器 - 控制器的工作 - 将结果返回给客户。

protected internal ContentResult Content(string content)

它看起来像是：

public static class MyHelper
{
    public static object GetAlbum(AlbumVO album)
    {
        return new
            {
                max_car = @ABookClient.maxCharsProjecName,
                trans_img = @ABookClient.Transparent_Image,
                show_description = @ABookClient.Show_Product_Description,
                product_type = "Album",
                obj = CreateObjAlbumVO(album),
            };
    }
}

public class AlbumController : Controller
{
    public ActionResult GetAlbums(int id)
    {
        var album = Context.GetAlbum(id);
        var convertedResult = MyHelper.GetAlbum(album);
        return Json(convertedResult);
    }
}

另外，我建议您查看AutoMapper来创建客户端响应对象

Answer 2

我认为这对于JSON结果的视图模型是有效的，因为您确实希望将Domain模型与发送回客户端的数据分开。使用视图模型还可以为您提供在域模型和视图（JSON）之间放置此映射的适当位置，这样您就不需要委派给帮助程序类。

AlbumInfo

你的控制器变得干净整洁：

public class AlbumInfo
{
    // ... define properties here
    public AlbumInfo(AlbumVO album)
    {
        // ... map properties here
    }
}

在MVC控制器外部使用Controller.Content c＃
