Looping in Dictionary using c#
Hi Experts,
I have a dictionary with key,value both int values (dictionary<int>,<int>) about 20 items and want to find if a given input falls within the range of key and value of dictionary.
Ex:
dictionary items = [100,150],
[200,225],
[500,599] etc
If user enters 150, since the 120 exist within the first item range ,I should return true and exit the loop
If user enters 160, since the 160 does not exist on any dictionary item' s range ,I should return false and exit the loop
If user enters 510 since the 510 exist within the third item range ,I should return true and exit the loop
I want to accomplish above task using c#

Why do you need a dictionary? (This is making things rather difficult for you. A dictionary is really good for rapid lookup of a random item.)

Hi ksd123;
Maybe you could use a collection of Tuple object as shown in the following code snippet.
Maybe you could use a collection of Tuple object as shown in the following code snippet.
// In place of using a Dictionary object to hold the data use a
// list of tuple's and define it like this.
List<Tuple<int, int>> items = new List<Tuple<int, int>>();
// Populate the data as Tuple objects
items.Add(Tuple.Create( 100, 150 ));
items.Add(Tuple.Create( 200, 225 ));
items.Add(Tuple.Create( 500, 599 ));
// Test Data from the user
int userInput = 160;
// The variable result will be true or false after going through the collection
bool result = items.Any( i => userInput >= i.Item1 && userInput <= i.Item2 );
