示例1: SamplesNameValueCollection
' The following code example demonstrates several of the properties and methods of ListDictionary.
Imports System.Collections
Imports System.Collections.Specialized
Public Class SamplesNameValueCollection
Public Shared Sub Main()
' Creates and initializes a new NameValueCollection.
Dim myCol As New NameValueCollection()
myCol.Add("red", "rojo")
myCol.Add("green", "verde")
myCol.Add("blue", "azul")
myCol.Add("red", "rouge")
' Displays the values in the NameValueCollection in two different ways.
Console.WriteLine("Displays the elements using the AllKeys property and the Item (indexer) property:")
PrintKeysAndValues(myCol)
Console.WriteLine("Displays the elements using GetKey and Get:")
PrintKeysAndValues2(myCol)
' Gets a value either by index or by key.
Console.WriteLine("Index 1 contains the value {0}.", myCol(1))
Console.WriteLine("Key ""red"" has the value {0}.", myCol("red"))
Console.WriteLine()
' Copies the values to a string array and displays the string array.
Dim myStrArr(myCol.Count) As String
myCol.CopyTo(myStrArr, 0)
Console.WriteLine("The string array contains:")
Dim s As String
For Each s In myStrArr
Console.WriteLine(" {0}", s)
Next s
Console.WriteLine()
' Searches for a key and deletes it.
myCol.Remove("green")
Console.WriteLine("The collection contains the following elements after removing ""green"":")
PrintKeysAndValues(myCol)
' Clears the entire collection.
myCol.Clear()
Console.WriteLine("The collection contains the following elements after it is cleared:")
