在C#中搜索SortedList对象
要在SortedList对象中进行搜索，代码如下-
示例
using System;
using System.Collections;
public class Demo {
public static void Main() {
SortedList list = new SortedList();
list.Add("1", "One");
list.Add("2", "Two");
list.Add("3", "Three");
list.Add("4", "Four");
list.Add("5", "Five");
list.Add("6", "Six");
list.Add("7", "Seven");
list.Add("8", "Eight");
Console.WriteLine("Key and Value of SortedList....");
foreach(DictionaryEntry k in list )
Console.WriteLine("Key: {0}, Value: {1}", k.Key , k.Value );
Console.WriteLine("Is the SortedList having the value? "+list.ContainsValue("Three"));
Console.WriteLine("The SortedList object has a fixed size? = "+list.IsFixedSize);
Console.WriteLine("Does the SortedList object contains key 10? = "+list.ContainsKey("10"));
}
}输出结果
这将产生以下输出-
Key and Value of SortedList.... Key: 1, Value: One Key: 2, Value: Two Key: 3, Value: Three Key: 4, Value: Four Key: 5, Value: Five Key: 6, Value: Six Key: 7, Value: Seven Key: 8, Value: Eight Is the SortedList having the value? True The SortedList object has a fixed size? = False Does the SortedList object contains key 10? = False
示例
让我们看另一个例子-
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
SortedList sortedList = new SortedList();
sortedList.Add("A", "1");
sortedList.Add("B", "2");
sortedList.Add("C", "3");
sortedList.Add("D", "4");
sortedList.Add("E", "5");
sortedList.Add("F", "6");
sortedList.Add("G", "7");
sortedList.Add("H", "8");
sortedList.Add("I", "9");
sortedList.Add("J", "10");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in sortedList) {
Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
}
Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count);
Console.WriteLine("\nEnumerator to iterate through the SortedList...");
IDictionaryEnumerator demoEnum = sortedList.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = "+ demoEnum.Value);
Console.WriteLine("Does the SortedList object contains key M? = "+sortedList.ContainsKey("M"));
Console.WriteLine("Does the SortedList object contains key H? = "+sortedList.ContainsKey("H"));
}
}输出结果
这将产生以下输出-
SortedList elements... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = D, Value = 4 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs = 10 Enumerator to iterate through the SortedList... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = D, Value = 4 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Does the SortedList object contains key M? = False Does the SortedList object contains key H? = True
