天需要些一个小工具，需要使用到多线程读写程序集，接口方法返回值类型需要为”IEnumerable<string>”这里用到了”yield return”，但是同时也使用了同步锁，为了确认代码没有问题，决定分析下 yield 的实现原理，测试代码如下：
class Program
{
public static void Main(string[] args)
{
IEnumerable<string> coll = CreateCollection(); foreach (string str in coll)
{
Console.WriteLine($"read: {str}");
}
} private static IEnumerable<string> CreateCollection()
{
using (BlockingCollection<string> collection = new BlockingCollection<string>())
{
lock (globalLock)
{
Exception err = null;
Task.Factory.StartNew(() =>
{
lock (globalLock)
{
for (int i = 0; i < 10; i++)
{
Thread.Sleep(100);
string value = $"value: {i}";
Console.WriteLine($"write: {value}");
collection.Add($"value: {i}");
Console.WriteLine($"end write: {value}");
}
}
}).ContinueWith((task) =>
{
collection.CompleteAdding();
err = task.Exception;
});
} foreach (string item in collection.GetConsumingEnumerable())
{
yield return item;
}
}
} private static readonly object globalLock = new object();
}
运行以上代码，结果如下：
结果是期望结果，但无法确定是否有其他问题，所以决定查看下IL代码，如下：

为了可以使之可以编译通过，修改了不合法的类名、变量名等，编译并运行的结果和源码一样，接下来就是仔细看其实现逻辑了。
对于Main方法，其逻辑即为通过方法 CreateCollection() 获取一个IEnumerable<string>对象，没啥好看的。
里查看 CreateCollection() 方法的实现，发现我们的逻辑都不见了，取而代之的是返回了一个 CreateCollection_1 对象实例，这就是我们的迭代器了。
1 private static IEnumerable<string> CreateCollection()
2 {
3 return new CreateCollection_1(-2);
4 }
那么 CreateCollection_1 类都做了什么呢？
我们发现，该类分别实现了 IEnumerable<string>, IEnumerable, IEnumerator<string>, IEnumerator, IDisposable 共五个接口，并且创建了两个新的内部类，DisplayClass1_0 和 DisplayClass1_1，分别对应我们 Task 启动的线程逻辑。
我们看 CreateCollection_1.MoveNext() 方法和 DisplayClass1_0.CreateCollection()方法，发现两个方法均加了锁，而且 CreateCollection_1 类有线程校验。
但是我们的要求是 CreateCollection() 方法内代码同步，既然编译器会自动添加锁，那么将代码改为如下形式会怎么样呢？
class Program
{
public static void Main(string[] args)
{
Task.Factory.StartNew(() =>
{
Console.WriteLine($"start ----------> {Thread.CurrentThread.ManagedThreadId}");
IEnumerable<string> coll = CreateCollection(); foreach (string str in coll)
{
Console.WriteLine($"read [{Thread.CurrentThread.ManagedThreadId}]: {str}");
}
}); Task.Factory.StartNew(() =>
{
Console.WriteLine($"start ----------> {Thread.CurrentThread.ManagedThreadId}");
IEnumerable<string> coll = CreateCollection(); foreach (string str in coll)
{
Console.WriteLine($"read [{Thread.CurrentThread.ManagedThreadId}]: {str}");
}
}); Console.ReadKey();
} private static IEnumerable<string> CreateCollection()
{
using (BlockingCollection<string> collection = new BlockingCollection<string>())
{
lock (globalLock)
{
Exception err = null;
Task.Factory.StartNew(() =>
{
Console.WriteLine("start new ...");
for (int i = 0; i < 10; i++)
{
Thread.Sleep(100);
string value = $"value: {i}";
Console.WriteLine($"[{Thread.CurrentThread.ManagedThreadId}] write: {value}");
collection.Add($"value: {i}");
Console.WriteLine($"[{Thread.CurrentThread.ManagedThreadId}] end write: {value}");
}
}).ContinueWith((task) =>
{
collection.CompleteAdding();
err = task.Exception;
}); foreach (string item in collection.GetConsumingEnumerable())
{
yield return item;
}
}
}
} private static readonly object globalLock = new object();
}
运行结果如下：
结果看起来是正确的，那么靠谱吗？还是到IL里面查找答案：

查看IL，我们发现在掉用 ‘<CreateCollection>d__1’.MoveNext() 方法时，加了锁，在调用 ‘<CreateCollection>d__1”<>m__Finally2′() 方法时（调用结束时）解了锁。
但是，如果我们在第一次调用 MoveNext() 之前，另一个线程调用了 CreateCollection() 方法，那么可能第二个线程可能先执行。
总结：
1、对于yield方法来说，在所有操作上加锁，并不能保证 yield 方法体内的代码同步；
2、yield方法体内的代码，只有在调用 MoveNext() 方法时才会调用；
