死锁案例

 1 public partial class Form1 : Form
 2     {
 3         public Form1()
 4         {
 5             InitializeComponent();
 6         }
 7 
 8         private void Form1_Load(object sender, EventArgs e)
 9         {
10 
11         }
12 
13         private   void button1_Click(object sender, EventArgs e)
14         {
15             Console.WriteLine("当前线程："+ Environment.CurrentManagedThreadId.ToString());
16             //ConfigureAwait(true) 任务结束后还回到原来的线程 ConfigureAwait(false) 不回到原来的线程 
17             //int result = await HeavyJob().ConfigureAwait(true);
18             int result =  HeavyJob().Result;
19             this.label1.Text = result.ToString();
20             Console.WriteLine("当前线程：" + Environment.CurrentManagedThreadId.ToString());
21         }
22 
23         async Task<int> HeavyJob()
24         {
25             await Task.Delay(6000);
26             return 12;
27         }
28     }

HeavyJob().Result会阻塞当前线程，直到
