ListDictionary.IsSynchronized属性用于获取一个值,该值指示ListDictionary是否已同步(线程安全)。

句法:

public bool IsSynchronized { get; }

返回值:该属性始终返回false

下面的程序说明了ListDictionary.IsSynchronized属性的使用:

范例1:

// C# code to check if ListDictionary
// is synchronized (thread safe)
using System;
using System.Collections;
using System.Collections.Specialized;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a ListDictionary named myDict
        ListDictionary myDict = new ListDictionary();
  
        myDict.Add("Australia", "Canberra");
        myDict.Add("Belgium", "Brussels");
        myDict.Add("Netherlands", "Amsterdam");
        myDict.Add("China", "Beijing");
        myDict.Add("Russia", "Moscow");
        myDict.Add("India", "New Delhi");
  
        // Check if ListDictionary is
        // synchronized (thread safe)
        Console.WriteLine(myDict.IsSynchronized);
    }
}

输出:

False

范例2:

// C# code to check if ListDictionary
// is synchronized (thread safe)
using System;
using System.Collections;
using System.Collections.Specialized;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a ListDictionary named myDict
        ListDictionary myDict = new ListDictionary();
  
        myDict.Add("1", "C");
        myDict.Add("2", "C++");
        myDict.Add("3", "Java");
        myDict.Add("4", "Python");
        myDict.Add("5", "C#");
        myDict.Add("6", "Data Structure");
  
        // Check if ListDictionary is
        // synchronized (thread safe)
        Console.WriteLine(myDict.IsSynchronized);
    }
}

输出:

False
