要将 HybridDictionary 条目复制到数组实例，代码如下 −
示例
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
HybridDictionary dict = new HybridDictionary();
dict.Add("1", "SUV");
dict.Add("2", "AUV");
dict.Add("3", "Utility Vehicle");
dict.Add("4", "MUV");
dict.Add("5", "Compact Car");
dict.Add("6", "Convertible");
Console.WriteLine("HybridDictionary Key and Value pairs...");
foreach(DictionaryEntry entry in dict){
Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
}
DictionaryEntry[] dictArr = new DictionaryEntry[10];
Console.WriteLine("
Copied to Array Instance...");
dict.CopyTo(dictArr, 2);
for (int i = 0; i < dictArr.Length; i++)
Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value);
}
}
输出
这将产生以下输出 −
HybridDictionary Key and Value pairs... 1 and SUV 2 and AUV 3 and Utility Vehicle 4 and MUV 5 and Compact Car 6 and Convertible Copied to Array Instance... Key = , Value = Key = , Value = Key = 1, Value = SUV Key = 2, Value = AUV Key = 3, Value = Utility Vehicle Key = 4, Value = MUV Key = 5, Value = Compact Car Key = 6, Value = Convertible Key = , Value = Key = , Value =
示例
现在让我们看另一个例子 −
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
HybridDictionary dict = new HybridDictionary(10);
dict.Add("1", "SUV");
dict.Add("2", "AUV");
dict.Add("3", "Utility Vehicle");
dict.Add("4", "MUV");
Console.WriteLine("HybridDictionary Key and Value pairs...");
foreach(DictionaryEntry entry in dict){
Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
}
DictionaryEntry[] dictArr = new DictionaryEntry[10];
Console.WriteLine("
Copied to Array Instance...");
dict.CopyTo(dictArr, 0);
for (int i = 0; i < dictArr.Length; i++)
Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value);
}
}
输出
这将产生以下输出 −
HybridDictionary Key and Value pairs... 1 and SUV 2 and AUV 3 and Utility Vehicle 4 and MUV Copied to Array Instance... Key = 1, Value = SUV Key = 2, Value = AUV Key = 3, Value = Utility Vehicle Key = 4, Value = MUV Key = , Value = Key = , Value = Key = , Value = Key = , Value = Key = , Value = Key = , Value =
