2. Something we can use Key as Primary key.
3. Using primary key we can get data.
4. Get Value by its Key.
5. It is a Generic, so reusable.

Used Namespaces:

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

Step 1: Adding items to Dictionary as KeyValuePair:

Dictionary<int, string> dic = new Dictionary<int, string>();
dic.Add(1, "Lajapathy");
dic.Add(2, "Parthiban");
dic.Add(3, "AnandBabu");
dic.Add(4, "Sathiya");

Step 2: Displaying the Dictionary items:

foreach (KeyValuePair<int, string> tempDic in dic)
{
Response.Write("Key :" + tempDic.Key + " value :" + tempDic.Value + "<br/>");
}

Step 4: Displaying items after removing:

foreach (KeyValuePair<int, string> tempDic in dic)
{
Response.Write("Key :" + tempDic.Key + " value :" + tempDic.Value + "<br/>");
}
