Initialize Dictionary Collection Using New Features in C# 3.0

Introduction

The C# 3.0 has lots of new features and new ways of object initialization. In this snippet I will show how to Initialize Dictionary Collection object with new feature using C# 3.0.

First i will show how is we are initialize the dictionary collection object in old version of the C# and then how is new version.

Old Version C# Code

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

namespace ConsoleApplication1
{
    public class DictionarySample
    {
        private Dictionary<int, string> OldDictionary()
        {
            Dictionary<int, string> collectionNames = new Dictionary<int, string>();
            collectionNames.Add(1, "RRaveen");
            collectionNames.Add(2, "Dhan");
            collectionNames.Add(3, "Abhi");
            collectionNames.Add(4, "Jana");

            return collectionNames;
        }
    }
}

New Version C# Code

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

namespace ConsoleApplication1
{
    public class DictionarySample
    {
        private Dictionary<int, string> NewDictionary()
        {
            Dictionary<int, string> collectionNames = new Dictionary<int, string>()
            {
                {1, "RRaveen"},
                {2, "Dhan"},
                {3, "Abhi"},
                {4, "Jana"}
            };
            return collectionNames;
        }
    }
}

The new version is easy and less line code.so writes code always using new features in .NET Framework. Hopes help.
