示例1: Main
//引入命名空间
using System;
using System.Collections;
using System.Collections.Generic;
public class Example
{
public static void Main()
{
// Create a new sorted list of strings, with string keys,
// and access it using the IDictionary interface.
//
IDictionary openWith = new SortedList<string, string>();
// Add some elements to the sorted list. There are no
// duplicate keys, but some of the values are duplicates.
// IDictionary.Add throws an exception if incorrect types
// are supplied for key or value.
openWith.Add("txt", "notepad.exe");
openWith.Add("bmp", "paint.exe");
openWith.Add("dib", "paint.exe");
openWith.Add("rtf", "wordpad.exe");示例2:
// The Item property is another name for the indexer, so you
// can omit its name when accessing elements.
Console.WriteLine("For key = \"rtf\", value = {0}.",
openWith["rtf"]);
// The indexer can be used to change the value associated
// with a key.
openWith["rtf"] = "winword.exe";
Console.WriteLine("For key = \"rtf\", value = {0}.",
openWith["rtf"]);
// If a key does not exist, setting the indexer for that key
// adds a new key/value pair.
openWith["doc"] = "winword.exe";
// The indexer returns null if the key is of the wrong data
// type.
Console.WriteLine("The indexer returns null"
+ " if the key is of the wrong type:");
Console.WriteLine("For key = 2, value = {0}.",
openWith[2]);
// The indexer throws an exception when setting a value
// if the key is of the wrong data type.
try
{
openWith[2] = "This does not get added.";
}
catch (ArgumentException)
{
Console.WriteLine("A key of the wrong type was specified"
+ " when assigning to the indexer.");
}示例3:
// Unlike the default Item property on the SorteList class
// itself, IDictionary.Item does not throw an exception
// if the requested key is not in the sorted list.
Console.WriteLine("For key = \"tif\", value = {0}.",
openWith["tif"]);
