本文實例講述了C#將HashTable中鍵列表或值列表復制到一維數組的辦法。分享給年夜家供年夜家參考。詳細以下：

上面的示例解釋若何將 Hashtable 中鍵的列表或值的列表復制到一維 Array 中。

using System;
using System.Collections;
public class SamplesHashtable {
 public static void Main() {
  // Creates and initializes the source Hashtable.
  Hashtable mySourceHT = new Hashtable();
  mySourceHT.Add( "A", "valueA" );
  mySourceHT.Add( "B", "valueB" );
  // Creates and initializes the one-dimensional target Array.
  String[] myTargetArray = new String[15];
  myTargetArray[0] = "The";
  myTargetArray[1] = "quick";
  myTargetArray[2] = "brown";
  myTargetArray[3] = "fox";
  myTargetArray[4] = "jumped";
  myTargetArray[5] = "over";
  myTargetArray[6] = "the";
  myTargetArray[7] = "lazy";
  myTargetArray[8] = "dog";
  // Displays the values of the target Array.
  Console.WriteLine( "The target Array contains the following before:" );
  PrintValues( myTargetArray, ' ' );
  // Copies the keys in the source Hashtable to the target Hashtable, starting at index 6.
  Console.WriteLine( "After copying the keys, starting at index 6:" );
  mySourceHT.Keys.CopyTo( myTargetArray, 6 );
  // Displays the values of the target Array.
  PrintValues( myTargetArray, ' ' );
  // Copies the values in the source Hashtable to the target Hashtable, starting at index 6.
  Console.WriteLine( "After copying the values, starting at index 6:" );
  mySourceHT.Values.CopyTo( myTargetArray, 6 );
  // Displays the values of the target Array.
  PrintValues( myTargetArray, ' ' );
 }
 public static void PrintValues( String[] myArr, char mySeparator ) {
  for ( int i = 0; i < myArr.Length; i++ )
   Console.Write( "{0}{1}", mySeparator, myArr[i] );
  Console.WriteLine();
 }
}
/* 
This code produces the following output.
The target Array contains the following before:
 The quick brown fox jumped over the lazy dog
After copying the keys, starting at index 6:
 The quick brown fox jumped over B A dog
After copying the values, starting at index 6:
 The quick brown fox jumped over valueB valueA dog
*/
