One Key to multiple values dictionary in C#? [duplicate]

Answer 1

A dictionary is a key-value pair, where the value is fetched depending on the key. The keys are all unique.

Now if you want a Dictionary with 1 keytype and multiple value types, you have a few options:

first is to use a Tuple

var dict = new Dictionary>()

The other is to use (with C# 4.0 and above):

var dict = new Dictionary()

the System.Dynamic.ExpandoObject can have value of any type.

using System;
using System.Linq;
using System.Collections.Generic;

public class Test {
   public static void Main(string[] args) {
        dynamic d1 = new System.Dynamic.ExpandoObject();
    var dict = new Dictionary();
        dict[1] = d1;
        dict[1].FooBar = "Aniket";
        Console.WriteLine(dict[1].FooBar);
        dict[1].FooBar = new {s1="Hello", s2="World", s3=10};
        Console.WriteLine(dict[1].FooBar.s1);
        Console.WriteLine(dict[1].FooBar.s3);
   }
}
