在C#中获取包含OrderedDictionary中的键的ICollection
要获取包含OrderedDictionary中的键的ICollection，代码如下-
示例
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
OrderedDictionary dict = new OrderedDictionary();
dict.Add("1", "One");
dict.Add("2", "Two");
dict.Add("3", "Three");
dict.Add("4", "Four");
dict.Add("5", "Five");
dict.Add("6", "Six");
dict.Add("7", "Seven");
dict.Add("8", "Eight");
ICollection col = dict.Keys;
String[] strKeys = new String[dict.Count];
col.CopyTo(strKeys, 0);
Console.WriteLine("显示键...");
for (int i = 0; i < dict.Count; i++) {
Console.WriteLine(strKeys[i]);
}
}
}输出结果
这将产生以下输出-
显示键... 1 2 3 4 5 6 7 8
示例
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() {
OrderedDictionary dict = new OrderedDictionary();
dict.Add("One", "John");
dict.Add("Two", "Tim");
dict.Add("Three", "Katie");
dict.Add("Four", "Andy");
dict.Add("Five", "Gary");
dict.Add("Six", "Amy");
ICollection col = dict.Keys;
String[] strKeys = new String[dict.Count];
col.CopyTo(strKeys, 0);
Console.WriteLine("显示键...");
for (int i = 0; i < dict.Count; i++) {
Console.WriteLine(strKeys[i]);
}
}
}输出结果
这将产生以下输出-
显示键... One Two Three Four Five Six
