Hello. I'm working on MVC application and I want to save Dictionary<string,> into DB I already have (generated with EF, DB first). I've didn't manage to find solutions, apparently EF doesn't support dictionary.
I will use this to associate different hashing and cryptic algorithms in my app. Here is sample code that illustrates what i'd like to save in db.

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1 {
    class Program {

        public delegate String AlgDelegte(String a, String b);

        public static String AlgFunc(String a, String b) {
            return String.Concat(a, b);
        }

        public static String Alg1Func(String a, String b) {
            return String.Concat(a, "\nBLA\n", b);
        }
        static void Main(string[] args) {
            AlgDelegte alg = new AlgDelegte(AlgFunc);
            AlgDelegte alg1 = new AlgDelegte(Alg1Func);
            Dictionary<String, AlgDelegte> algorithms = new Dictionary<string, AlgDelegte>();

            algorithms.Add("zeroth", alg);
            algorithms.Add("first", alg1);

            Console.WriteLine(algorithms["first"]("a", "b"));

        }
    }
}

Thanks in advance.

Not clear what you are trying to achieve with this code sample. Storing and retrieving dictionary content using relational database is quite simple; please see my answer.

I think he wants to save an entire dictionary as a single field in the database... like a string or int.

The concept of dictionary if very close to relational model. You just need to have a table of key-value pairs, where a dictionary key could be a primary table key. If you have to store several different dictionaries in a single table, the key uniqueness can be violated. In this case, use a compound key: one columns identifying a dictionary instance, another one — a dictionary key. Please see:

Thanks, this helps. But is it possible to save these function delegates as value in table?
