Hochladen Bild in Asp.net Mvc-Controller

Question

Ich habe ein Upload-Formular, und ich mag, dass meine Informationen wie ein Bild und ein anderes Feld passieren, aber ich weiß nicht, wie ich Bild hochladen ..

Dies ist Meine Modellklasse

public partial class NewProductCategory 
 
    { 
 
     public string ProductName { get; set; } 
 
     public string ProductDescription { get; set; } 
 
     public string ProductPrice { get; set; } 
 
     public string ProductImage { get; set; } 
 
     public string ProductQuantity { get; set; } 
 
     public Nullable<bool> ProductStatus { get; set; } 
 
     public Nullable<int> CategoryId { get; set; } 
 

 
     public HttpPostedFileBase user_image_data { get; set; } 
 
     public virtual Category Category { get; set; } 
 

 
    }

[HttpPost] 
     [ValidateAntiForgeryToken] 
     public ActionResult Create(NewProductCategory productcategory, HttpPostedFileBase file) 
     { 
      if (ModelState.IsValid) 
      { 
       ProductCategory newproductCategory = new ProductCategory(); 
       string path = Path.Combine(Server.MapPath("~/Content/files"), Path.GetFileName(file.FileName)); 
       file.SaveAs(path); 
       newproductCategory.ProductDescription = productcategory.ProductDescription; 
       newproductCategory.ProductQuantity = productcategory.ProductQuantity; 
       newproductCategory.ProductStatus = productcategory.ProductStatus; 

       newproductCategory.CategoryId = productcategory.CategoryId; 

       db.ProductCategories.Add(newproductCategory); 
       db.SaveChanges(); 
       return RedirectToAction("Index"); 
      } 

      ViewBag.CategoryId = new SelectList(db.Categories, "CategoryId", "Name", productcategory.CategoryId); 
      return View(productcategory); 
     }
