Hello, i am new to asp.net MVC so please dont judge me,

I have a model

C#

namespace WebApplication1.Models
{
    public class productDB
    {
        public int Producttype { get; set; }
        public string Productquantity { get; set; }

i have this calculation in my controller:

C#

public ActionResult prog()
        {
            var TypeQty = db.productDB.GroupBy(fu => fu.Producttype)
            .Select(g => new { Name = g.Key, Count = g.Count() });
            return TypeQty;
//running into a problem here aswell "Cannot imlicitly convert type"

        }

How do i pass the result of calculation to my view? thanks for your help!

Solution 1

You should create a concrete class with a Name and Count property and create a list of those

C#

var TypeQty = db.productDB.GroupBy(fu => fu.Producttype)
            .Select(g => new YourClassNameHere{ Name = g.Key, Count = g.Count() });

Your model will now be

@model IEnumerable<yourclassnamehere>

Should i create that class in the controller or model?

Anywhere, make sure you do not miss the namespace it is created in. :-)

Create it in the Models folder.

You need to create the database context before you can use it. Go through this tutorial, it shows you everything from start to finish
