SortedListがC＃で読み取り専用かどうかを確認します

SortedListが読み取り専用かどうかを確認するには、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 list = new SortedList();
      list.Add("One", "IT");
      list.Add("Two ", "Operations");
      list.Add("Three", "Marketing");
      list.Add("Four", "Purchase");
      list.Add("Five", "Sales");
      list.Add("Six", "Finance");
      Console.WriteLine("SortedList elements...");
      foreach(DictionaryEntry d in list) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("\nList of values...SortedList");
      IList col = list.GetValueList();
      foreach(string res in col) {
         Console.WriteLine(res);
      }
      Console.WriteLine("\nSortedList is read-only? = "+list.IsReadOnly);
   }
}

出力

これにより、次の出力が生成されます-

SortedList elements...
Five Sales
Four Purchase
One IT
Six Finance
Three Marketing
Two  Operations
List of values...SortedList
Sales
Purchase
IT
Finance
Marketing
Operations
SortedList is read-only? = False

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 list = new SortedList();
      list.Add("One", "Finance");
      list.Add("Two", "Marketing");
      list.Add("Three", "Sales");
      list.Add("Four", "Purchase");
      list.Add("Five", "Operations");
      list.Add("Six", "IT");
      Console.WriteLine("SortedList elements...");
      foreach(DictionaryEntry d in list) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("\nIndex at key One = "+list.IndexOfKey("One"));
      ICollection col = list.Keys;
      Console.WriteLine("\nCollection of Keys...");
      foreach(string res in col)
         Console.WriteLine(res);
      Console.WriteLine("\nSortedList is read-only? = "+list.IsReadOnly);
   }
}

出力

これにより、次の出力が生成されます-

SortedList elements...
Five Operations
Four Purchase
One Finance
Six IT
Three Sales
Two Marketing
Index at key One = 2
Collection of Keys...
Five
