本文实例讲述了C#将HashTable中键列表或值列表复制到一维数组的方法。分享给大家供大家参考。具体如下：

下面的示例说明如何将 Hashtable 中键的列表或值的列表复制到一维 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(); }}

希望本文所述对大家的C#程序设计有所帮助。
