I'm trying to get all Countries from my database for a combo box.
This is my code for it:
public IQueryable<Customer> GetAllCountries()
{
var query = from e in Entities
select e.Country;
return query;
}
It gives me an error at return query;
I only want the Countries for my combo box, even though there are cities and all sorts in the Customer class.
I managed to fix it by using IQueriable<string> instead of Customer!

here is the whole association model of my database
the problem is that I need to read the list of Equipment displayed at each Employee
*An employee has one or more Post
*A Post has one or more Equipment
I created the backend part with .NET
I tried to read the list of posts of an employee and then read the list of Equipment by the id of each post
/*********************************/
[HttpGet]
public async Task<IEnumerable<GetEquiPostDto>> GetEmpPostListAsync(string id)
{
var EmpPost=(await PostRepository.GetEmppPostAsync(id))
.Select(EmpPost=>EmpPost.GetEmpPostDto()).ToList();
for(int i=0;i<EmpPost.Count;i++)
{
var EquiPost=(await EquipRepository.GetEquippPostAsync(EmpPost[i].PostId))
.Select(EquiPost=>EquiPost.GetEquiPostDto());
}
return EquiPost;
}

I'm new to C#.
I have a method that returns an object with the List of objects inside.
0 {{DapperRow, RecordedFormID = 'id1'}} object {Dapper.SqlMapper.DapperRow}
1 {{DapperRow, RecordedFormID = 'id2'}} object {Dapper.SqlMapper.DapperRow}
How can I get those ids as strings?
Here is a screenshot
You can use System.Linq namespace and do this:
yourObject.Select(x => x.RecordedFormID);

I need to get diagram`s name of specific elements. Is it possible ?
I added elements note with specific stereotypu using profile to EA project. Then i want create a plugin where i find this notes and diagram names where they are located. (i want export notes and diagram names to excel)....PS: Sorry for my bad english
Issue a SQL like
Repository.SQLQuery("SELECT t_diagram.name FROM t_diagramobjects AS dobj INNER JOIN t_diagram ON dobj.diagram_id = t_diagram.diagram_id WHERE t_diagramobjects.Object_ID = <elementID>"
Just replace <elementID> with the element's elementID. You could alternatively retrieve the diagram GUID (t_diagram.ea_guid') and get the diagram details viaRepostory.GetDiagramByGUID`.

public class itemObject { public string items; }
values - item = "name1,name2" or items = "item3"
Need linq to split by ',' if exists else one string array.
This doesnt require linq, its the default behaviour of String.Split
var array = items.Split(',');

4:25 adds a new object in the lineCollection if product does not exist in lineCollection, but at 24:25 it shows duplicating orders? Did i misunderstood how it works?
https://github.com/jedjad/GitHubVS2013
Because the products in duplicate values are not same objects. They may have same names, quantity etc, but initializing a class with same values does not mean that it is the same object as the one initialized before. They are like 2 different apples with same color and size.
If you say that 2 products are same whenever the names are same, then implement IEquatable<Product> in Product class.
public bool Equals(Product other)
{
return Name == other.Name;
}
