再把程式修改一下
C# Multiple Threads
thread.Start()
按下 F5執行，可以看到 Console控制台輸出是： 兩個同時執行的線程混合交叉的顯示
Hello from Main()和Hello from DifferentMethod()。

internal class Program
{
//Main是主線程的線程
static void Main(string[] args)
{
var thread = new Thread(DifferentMethod); //建立另一個線程
thread.Start(); //開始線程
while (true) {
Console.WriteLine("Hello from Main()");
}
}
//另一個線程的開始
static void DifferentMethod( ) {
while (true) {
Console.WriteLine("Hello from DifferentMethod()");
}
}
}
執行結果：(按Ctrl+C結束)

Hello from Main()
Hello from DifferentMethod()
Hello from Main()
Hello from Main()
Hello from DifferentMethod()
Hello from DifferentMethod()
Hello from Main()
Hello from DifferentMethod()
參數化線程 thread.Start(object? parameter)
讓輸出變得更有趣，使用參數化線程…
按下 F5執行，可以看到 Console控制台內容：
輸出的數字在變化，事實上，這些線程是同時在執行的，只是它們在爭奪控制台視窗以將其輸出印出。

結論
所以Thread執行緒(線程)主要的優點是：
如果你可以將工作分解成邏輯塊，在其後立即發送一堆線程，你會發現可以更快得完成更多的工作。
