原文:https://www . geesforgeks . org/c-sharp-check-if-list dictionary-is-synchronized-thread-safe/

列表词典。IsSynchronized 属性用于获取一个值，该值指示列表字典是否同步(线程安全)。

语法:

public bool IsSynchronized { get; }

返回值:该属性始终返回 false 。

以下是说明列表词典使用的程序。同步属性:

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

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
