Csharp/CSharp Tutorial/Generic/Generic SortedList
Use the ContainsKey() method to check if mySortedList contains a key
<source lang="csharp">using System; using System.Collections; class MainClass {
public static void Main() { SortedList mySortedList = new SortedList(); mySortedList.Add("NY", "New York"); mySortedList.Add("FL", "Florida"); mySortedList.Add("AL", "Alabama"); mySortedList.Add("WY", "Wyoming"); mySortedList.Add("CA", "California"); foreach (string myKey in mySortedList.Keys) { Console.WriteLine("myKey = " + myKey); } foreach(string myValue in mySortedList.Values) { Console.WriteLine("myValue = " + myValue); } if (mySortedList.ContainsKey("FL")) { Console.WriteLine("mySortedList contains the key FL"); } }
}</source>
myKey = AL myKey = CA myKey = FL myKey = NY myKey = WY myValue = Alabama myValue = California myValue = Florida myValue = New York myValue = Wyoming mySortedList contains the key FL
Use the keys to obtain the values from a generic SortedList<TK, TV>
<source lang="csharp">using System; using System.Collections.Generic;
class MainClass {
public static void Main() { SortedList<string, double> sl = new SortedList<string, double>(); sl.Add("A", 7); sl.Add("B", 5); sl.Add("C", 4); sl.Add("D", 9); // Get a collection of the keys. ICollection<string> c = sl.Keys; foreach(string str in c) Console.WriteLine("{0}, Salary: {1:C}", str, sl[str]); Console.WriteLine(); }
}</source>
A, Salary: $7.00 B, Salary: $5.00 C, Salary: $4.00 D, Salary: $9.00
