![]() The Run method calls the following two methods that provide the primary interaction with the user: When an instance of the SkiLift class is constructed, it creates a Queue object that will be used to store Skier instances. Skier nextSkier = (Skier)_theLift.Dequeue() Ĭonsole.WriteLine(" The IDictionaryEnumerator interface, shown in the following code, is a specialized version of the IEnumerator interface that’s well-suited for enumerating dictionary-style collections: For example, many data structures based on trees or hashing are difficult to iterate using the IEnumerator interface. Remove Removes a specific key and its associated value from the collection.Ĭlasses that implement IDictionary often have a nonlinear method of associating keys with values. IDictionaryEnumerator provides a richer interface than IEnumerator and is discussed in more detail shortly. GetEnumerator Returns an IDictionaryEnumerator interface for the collection. If the key already exists, an ArgumentException exception is thrown.Ĭlear Removes all key/value pairs from the collection.Ĭontains Returns true if a specified key exists in the collection or false if the key isn’t found. Values Returns an ICollection interface that can be used to interact with all values in this collection.Īdd Adds a new key/value pair to the collection. Keys Returns an ICollection interface that can be used to interact with all keys in this collection. IsReadOnly Returns true if the collection is read-only or false if items can be added to the collection. IsFixedSize Returns true if the size of the collection is fixed or false if new keys can be added. The other methods and properties declared by IDictionary are listed here: If the collection has a fixed size, attempting to add a new item will result in a NotSupportedException exception being thrown. If the collection exposing IDictionary doesn’t have a fixed size, a new item can be added to the collection using the indexer. A get operation on the indexer returns the value mapped to the key and a set operation overwrites the item currently associated with the key. IDictionary specifies an indexer that uses the collection key as the index parameter. The use of these properties is covered, along with other multithreaded programming topics, in Chapter 10. All collections expose the CopyTo method to provide a standard way for a collection to copy its contents to an array.Īll collection classes also implement the IsSynchronized and SynchRoot properties to support basic multithreaded programming. All collections must implement the Count property so that clients can determine the number of objects in a collection. SynchRoot Returns an object used to synchronize multithreaded access to the collectionĬopyTo Copies the objects in the collection to an arrayīy factoring the common properties and methods for collections into the ICollection interface, a basic contract is defined for all collection classes in the. IsSynchronized Returns true if the collection is thread-safe otherwise, returns false to the DB, provided to her by SaveRep method from Program class.The members of the ICollection interface are described here:Ĭount Returns the number of objects stored in the collection This method should save all data (RepID,Data1,Data2) SqlConnection connection = new SqlConnection(strConnectionString) String strConnectionString = Security=True database=DataBase") data to this method will be provided from another method. This method should send the data above to method Save() in Report class I apologize if the question is badly formulated, I am really stuck at this, please help. I'm having class Report and class Program, what I want to accomplish (no luck so far) is to send data from class Program and method SaveRep() to class Report method Save() and save it in this method. ![]()
