C＃でSortedListに含まれる要素の数を取得します

SortedListに含まれる要素の数を取得するには、コードは次のとおりです-

例

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);
      sortedList.Clear();
      Console.WriteLine("Count of SortedList (updated) = "+sortedList.Count);
   }
}

出力

これにより、次の出力が生成されます-

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 Count of SortedList (updated) = 0

例

別の例を見てみましょう-

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args){
      SortedList sortedList = new SortedList();
      sortedList.Add("One", "1");
      sortedList.Add("Two", "2");
      sortedList.Add("Three", "3");
      sortedList.Add("Four", "4");
      sortedList.Add("Five", "5");
      sortedList.Add("Six", "6");
      sortedList.Add("Seven", "7");
      sortedList.Add("Eight", "8");
      sortedList.Add("Nine", "9");
      sortedList.Add("Ten", "10");
      Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count);
      Console.WriteLine("Enumerator to iterate through the SortedList...");
      IDictionaryEnumerator demoEnum = sortedList.GetEnumerator();
      while (demoEnum.MoveNext())
         Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
   }
}

これにより、次の出力が生成されます-

Count of SortedList key-value pairs = 10
Enumerator to iterate through the SortedList...
Key = Eight, Value = 8
Key = Five, Value = 5
Key = Four, Value = 4
Key = Nine, Value = 9
Key = One, Value = 1
Key = Seven, Value = 7
Key = Six, Value = 6
Key = Ten, Value = 10
Key = Three, Value = 3
Key = Two, Value = 2
