How to read values with different datatype in Entity Framework?

Question

I have a query (simple SELECT statement) which returns Id and Name where Id is int and Name is string . The query returns result in SSMS. I am trying to get that record using EF in my MVC application. I can get that value if I create custom class but not of I use dictionary . Second option doesn't throw any error but it comes with zero record.

How can I read the value without creating custom class?

C# Logic:

// Option-1 = Works
var sql = @"SELECT UnitNumber, 
                   UnitName
            FROM dbo.MyTable 
            WHERE Id = @p0
            AND ScriptId = @p1";

var result = context.Database.SqlQuery<MyClass>(sql, callCenterId, id);

public class MyClass
{
    public int UnitNumber { get; set; }
    public string UnitName { get; set; }
}


// Option-2 = Doesn't Work
var sql = @"SELECT UnitNumber, 
                   UnitName
            FROM dbo.MyTable 
            WHERE Id = @p0
            AND ScriptId = @p1";

var result = context.Database.SqlQuery<Dictionary<int, string>>(sql, callCenterId, id);

SQL Query:

SELECT UnitNumber, 
       UnitName
FROM dbo.MyTable 
WHERE Id = 1
AND ScriptId = 10

SQL Output:

UnitNumber  UnitName

You need to project your resultset into a dictionary, like this :

var result = context.Database.SqlQuery<MyClass>(sql, callCenterId, id)
             .ToDictionary(o => o.UnitNumber, o => o.UnitName);

or

var result = context.Database.SqlQuery<MyClass>(sql, callCenterId, id)
         .Select(x=> new KeyValuePair<int, string>(x.UnitNumber, x.UnitName))
         .ToDictionary(x=>x.Key, x=>x.Value);
