In this article i am going to show how to use generics using dictionary .
basically dictionary uses key value pair to display record.
we can add , remove , insert data in dictionary using key / value pair .
but this is that you need to follow some rules.
To declare or define dictionary is
Dictionary <string , Int32> myFirstdictionary=new Dictionary<string,int>();
here my dictionary name is myFirstdictionary.
where i m pasing key as string and value will be int32,
now to add value in data using key we use key and pair value.
like this...
myFirstdictionary.Add("dev", 1);
where "dev" is string
and 1 is value type of int.
Now to fetch data fromdictionary row by row we need to use for or foreach loop.
foreach(KeyValuePair<string, Int32> keys in myFirstdictionary)
{
Response.Write(keys.Key +"/"+ keys.Value + "<br/>");
}
it will print data like this as printed below.
