Can't I use aggregate functions on View via model? Because model is already on the view and it has all the data. Besides I have to calculate 2 more sums. If your way is the only one, how can I send those all sums to the View in the controller?
[HttpGet]
public ActionResult FakeAnalyze(string image)
{
ImageVm vm = new ImageVm();
//string img = string.Empty;
using (StreamReader file = System.IO.File.OpenText(@"C:\PlanogramWebApp\PlanogramWebApp\images\test.json"))
{
JsonSerializer serializer = new JsonSerializer();
vm = (ImageVm)serializer.Deserialize(file, typeof(ImageVm));
}
// Convert byte[] to Base64 String
string base64String = vm.ImageUrl;
vm.ImageUrl = "data:image/png; base64," + base64String;
return View("Index", vm);
}
edit: I got what you mean :)
@Model.lines[i].products.Sum(m => m.master_count)

Razor how to sum model data
Jan 09, 2019 10:51 AM|cenk1536|LINK
Hello guys,
I need to get sum of model data but couldn't manage how to implement it. Any help would be great?
Thanks in advance.
<div class="col-sm-3 c217"> @if (Model.lines != null) { <h3 class="center">Results</h3> <table class="table table-bordered table-responsive table-hover" style="font-size: 11px !important;"> <thead> <tr> <th>Name </th> <th>Master</th> <th>Count </th> <th>Average</th> <th>Position</th> </tr> </thead> @for (int i = 0; i < Model.lines.Count(); ++i) { for (int k = 0; k < Model.lines[i].products.Count(); ++k) { if (Model.lines[k].products != null) { <tr> <td> @Model.lines[i].products[k].name </td> <td> @Model.lines[i].products[k].master_count </td> <td> @Model.lines[i].products[k].count </td> <td> @Model.lines[i].products[k].count_average </td> <td> @Model.lines[i].products[k].position_average </td> </tr> } } <tr> <td> Total </td> <td> @Model.Sum(Model.lines[i].products[k].master_count) </td> </tr> } </table> } </div>Here is my model:
public class ImageVm { public string ImageUrl { get; set; } public Line[] lines { get; set; } } public class Line { public int number { get; set; } public Product[] products { get; set; } public string products_position_average { get; set; } public string line_average { get; set; } } public class Product { public int id { get; set; } public string name { get; set; } public int count { get; set; } public int master_count { get; set; } public string count_average { get; set; } public string position_average { get; set; } }All-Star

The linq syntax is...
int masterCountTotalPerProduct = 0; using (StreamReader file = File.OpenText("data.json")) { JsonSerializer serializer = new JsonSerializer(); JsonResponse response = (JsonResponse)serializer.Deserialize(file, typeof(JsonResponse)); masterCountTotalPerProduct = response.lines[0].products.Sum(m => m.master_count); }Linq reference docs.
