C#中如何判断一个线程是否是主线程

如何判断一个线程是否是主线程

csharp
using System;
using System.Threading;
class Program
{
    static void Main()
    {
        Thread workerThread = new Thread(WorkerMethod);
        workerThread.Start();
        if (Thread.CurrentThread.ManagedThreadId == 1)
        {
            Console.WriteLine("当前线程是主线程");
        }
        else
        {
            Console.WriteLine("当前线程不是主线程");
        }
    }
    static void WorkerMethod()
    {
        if (Thread.CurrentThread.ManagedThreadId == 1)
        {
            Console.WriteLine("Worker方法正在主线程中执行");
        }
        else
        {
            Console.WriteLine("Worker方法不在主线程中执行");
        }
    }
}
