pass multiple data as a list to View in MVC - asp.net-mvc

Question

How to pass LINQ data to View. I have used below code but it throwing conversion error.
namespace WebApplication1.DataContext
{
public class Repositary
{
public ProductMaster productMaster { get; set; }
public ProductDetail productDetail { get; set; }
}
}`
Action Method:-
public ActionResult ProductMasterWithDetails()
{
Model1 db=new Model1();
Repositary rep = new Repositary();
var varResult= from pm in db.ProductMasters join pd in db.ProductDetails on pm.ProductId equals pd.ProductId select new { pm.ProductId, pm.ProductName, pd.Price, pd.ManufactureBy };
ViewBag.result = varResult.ToList();
return View();
}
Error: Cannot initialize type 'WebApplication1.DataContext.Repositary'
with a collection initializer because it does not implement
'System.Collections.IEnumerable'
C:\Users\msnsh\onedrive\documents\visual studio
2013\Projects\WebApplication1\WebApplication1\Controllers\ProductController.cs 55 141 WebApplication1
In View:
#foreach (var result in ViewBag.result){
}
I have two model classes as follows.
namespace WebApplication1.DataContext
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity.Spatial;
[Table("ProductMaster")]
public partial class ProductMaster
{
public ProductMaster()
{
ProductDetails = new HashSet<ProductDetail>();
}
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public int ProductId { get; set; }
[StringLength(50)]
public string ProductName { get; set; }
public virtual ICollection<ProductDetail> ProductDetails { get; set; }
}
}
namespace WebApplication1.DataContext
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity.Spatial;
public partial class ProductDetail
{
public int? Price { get; set; }
[StringLength(50)]
public string ManufactureBy { get; set; }
public int? ProductId { get; set; }
[Key]
public int ProdDetailsId { get; set; }
public virtual ProductMaster ProductMaster { get; set; }
}
}
If we have two model classes then how to replace below single Model namespace ?
#model IEnumerable
I cannot create a single class as below, because my model has two classes,
public Class ProductCustomModel
{
public int ProductId { get; set; }
public int ProductName { get; set; }
public int Price { get; set; }
public int ManufactureBy { get; set; }
}
Here is my Model1 Class.
namespace WebApplication1.DataContext
{
using System;
using System.Data.Entity;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Data.Entity.Spatial;
public partial class Model1 : DbContext
{
public Model1()
: base("name=Model1")
{
}
public virtual DbSet<ProductDetail> ProductDetails { get; set; }
public virtual DbSet<ProductMaster> ProductMasters { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<ProductDetail>()
.Property(e => e.ManufactureBy)
.IsUnicode(false);
modelBuilder.Entity<ProductMaster>()
.Property(e => e.ProductName)
.IsUnicode(false);
}
}
}

Answer 1

If you getdata in varResult than you should try,
In Conroller.
Model1 db=new Model1();
var varResult= (from pm in db.ProductMasters join pd in db.ProductDetails on pm.ProductId equals pd.ProductId select new { pm.ProductId, pm.ProductName, pd.Price, pd.ManufactureBy }).ToList();
return View("path to the view",varResult);
In View
#model ModelName
#foreach (var result in Model){
}

Answer 2

You should need to change the ViewBag to the customModel/Class which will send the List to your view.
Models:
namespace WebApplication1.DataContext
{
public class Repositary
{
public ProductMaster productMaster { get; set; }
public ProductDetail productDetail { get; set; }
}
public Class ProductCustomModel
{
public int ProductId { get; set; }
public int ProductName { get; set; }
public int Price { get; set; }
public int ManufactureBy { get; set; }
}
}
Change your action Method to this:
public ActionResult ProductMasterWithDetails()
{
Model1 db=new Model1();
Repositary rep = new Repositary();
var varResult= from pm in db.ProductMasters join pd in db.ProductDetails on pm.ProductId equals pd.ProductId select new { pm.ProductId, pm.ProductName, pd.Price, pd.ManufactureBy };
//Make your List Here like this and add the values in it.
List<ProductCustomModel> productCustomModelList = new List<ProductCustomModel>();
Foreach(ProductCustomModel item in varResult)
{
ProductCustomModel singleData = new ProductCustomModel();
ProductId = item.ProductId,
ProductName = item.ProductName,
Price = item.Price,
ManufactureBy = item.ManufactureBy
productCustomModelList.Add(singleData);
}
return View(productCustomModelList);
}
In the View(.cshtml)
#model IEnumerable<WebApplication1.DataContext.ProductCustomModel>
#foreach (var result in Model){
//.. operations
}
