The IDictionary interface defines the behavior of a non-generic collection that maps unique keys to values. A key is an object that you use to retrieve a value at a later date. Thus, a collection that implements IDictionary stores key/value pairs. Once the pair is stored, you can retrieve it by using its key. IDictionary inherits ICollection and IEnumerable. The methods declared by IDictionary are summarized in Table 24-3. Several methods throw an ArgumentNullException if an attempt is made to specify a null key and null keys are not allowed. To add a key/value pair to an IDictionary collection, use Add( ). Notice that the key and its value are specified separately. To remove an element, specify the key of the object in a call to Remove( ). To empty the collection, call Clear( ). You can determine whether a collection contains a specific object by calling Contains( ) with the key of the desired item. GetEnumerator( ) obtains an enumerator compatible with an IDictionary collection. This enumerator operates on key/value pairs.

FE8 through FFF. A loopback address is ::1.

This program reads a string using cgets( ).

This quadratic has to be solved by formula:

// Use a property in an interface. using System; public interface ISeries { // An interface property. int Next { get; // return the next number in series set; // set next number } } // Implement ISeries. class ByTwos : ISeries { int val; public ByTwos() { val = 0; } // Get or set value. public int Next { get { val += 2; return val; } set { val = value; } } } // Demonstrate an interface property. class SeriesDemo3 { static void Main() { ByTwos ob = new ByTwos(); // Access series through a property. for(int i=0; i < 5; i++) Console.WriteLine("Next value is " + ob.Next); Console.WriteLine("\nStarting at 21"); ob.Next = 21;

An exclusive OR, usually abbreviated XOR, will turn a bit on only if the bits being compared are different. For example, 127 ^ 120 is 01111111 01111000 ^ --------------00000111 127 in binary 120 in binary bitwise XOR result
