我在MVC网站的投资组合部分有两个模型
public class PortfolioEntry
{
public int ID { get; set; }
[Display(Name="Project Name")]
public string Name { get; set; }
[Display(Name="Created for")]
public string Client { get; set; }
public string Description { get; set; }
[Display(Name ="Started at")]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime Start { get; set; }
[Display(Name ="Ended by")]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime End { get; set; }
[Display(Name ="Skills used")]
public string Category { get; set; }
[Display(Name ="GitHub Link")]
public string GitHubLink { get; set; }
[Display(Name ="Solution Screenshots")]
public virtual ICollection<ScreenShot> ScreenShots { get; set; }
}
第二个：
public enum ScreenShotType
{
[Display(Name = "Use case Diagram")]
UseCase,
[Display(Name = "Behaviour Diagram")]
Behavior,
[Display(Name ="Class Diagram")]
ClassStructure,
[Display(Name ="Main View")]
MainPage,
[Display(Name = "Additional View")]
SomthingCool
}
public class ScreenShot
{
public int ID { get; set; }
public string Description { get; set; }
[Display(Name="Screenshot Type")]
public ScreenShotType Type { get; set; }
public string ImageURL { get; set; }
public int Sorting { get; set; }
public int PortfolioEntryID { get; set; }
}
}
现在我要做的是创建一个子窗体，允许我动态上传ScreenShot并在数据库中为它创建一条新记录（点击浏览...，选择照片，填写信息然后点击＆＃34;上传＆＃34;）。 然后返回＆＃34; Main＆＃34;表格，所以我可以上传另一个或完全保存整个。
我应该怎么做？我尝试在控制器中创建一个新动作：
public async Task<ActionResult> UploadPhoto([Bind(Include = "ID,Name,Client,Description,Start,End,GitHubLink")] PortfolioEntry portfolioEntry, HttpPostedFileBase uploadedFile, string description, int sorting)
{
if (uploadedFile!=null && uploadedFile.ContentLength>0 && uploadedFile.ContentType.Contains("image"))
{
string extension = Path.GetExtension(uploadedFile.FileName.ToString().ToLower());
string fileName = "PorfolioImage" + String.Format("{0:D5}", db.Photos.Count()) + extension;
var path = Path.Combine(Server.MapPath("~/Pictures/ScreenShots"), fileName);
uploadedFile.SaveAs(path);
var screenshotToAdd = new ScreenShot
{
Description = description,
Sorting = sorting,
PortfolioEntryID = portfolioEntry.ID,
ImageURL = fileName
};
await db.SaveChangesAsync();
}
return(View(portfolioEntry));
}
但： 1.它没有看到上传的文件 2.即使它确实看到了文件，它似乎也没有从Bind注册实体
我已经看过一个解决方案：mkozicki但在重新编写方法之前，我想知道这是否是我应该采取的路径。

编辑：根据后续添加视图：

@{
ViewBag.Title = "Create";
}
