Answer 1

Here is an example for you

 using System;
 using System.Collections.Generic;

class Program
{
 static void Main()
 {
  Dictionary test = new Dictionary();
  test.Add("one", "value");
//
// Use TryGetValue to avoid KeyNotFoundException.
//
string value;
if (test.TryGetValue("two", out value))
{
    Console.WriteLine("Found");
}
else
{
    Console.WriteLine("Not found");
}
  }
}
