how to initialize dictionary as (key,value,value) pair in C#

Question

I want to store values as key,value,value pair. My data is of type

Key -> int & both values -> ulong,

How to initialize & fet

Answer 1

You can declare a class that stores both values and then use an ordinary dictionary. For example:

class Values {
    ulong Value1 {get;set;}
    ulong Value2 {get;set;}
}

var theDictionary=new Dictionary<int, Values>;

theDictionary.Add(1, new Values {Value1=2, Value2=3});

Answer 2

Create a structure to store your values:

struct ValuePair
{
    public ulong Value1;
    public ulong Value2;
}

Dictionary initialization:

Dictionary<int, ValuePair> dictionary = new Dictionary<int, ValuePair>();

Maybe List is enough, if you use int as key?

List:

List<ValuePair> list = new List<ValuePair>();

ValuePair can be added to the list as following:

list.Add(new ValuePair { Value1 = 1, Value2 = 2 });

Answer 3

I'm not sure I understand your question correctly, but if you want to store more than one value in the value part of Dictionary, you could do something like this:

var dic = new Dictionary<int,KeyValuePair<ulong,ulong>>();

You can use insert into the dictionary like this:

dic.Add(42, new KeyValuePair<ulong, ulong>(42, 42));
dic.Add(43, new KeyValuePair<ulong, ulong>(43, 43));

And fetch the values like so:

foreach (var a in dic)
{
    Console.WriteLine("Key: {0}, Value1: {1}, Value2: {2}",
        a.Key, a.Value.Key, a.Value.Value);
}
