c# - ThreadLocal 属性

Question

如果我们有一个 ThreadLocal 属性(每个线程都有其唯一的属性)，那么哪个是正确的(我们不想使用自动 setter/getter):

A)

private ThreadLocal<MyClass> _someProperty = new ThreadLocal<MyClass>();

public ThreadLocal<MyClass> SomeProperty
{
    get
    {
        return _someProperty.Value;
    }
    set
    {
        _someProperty.Value = value;
    }
}

B)

private ThreadLocal<MyClass> _someProperty = new ThreadLocal<MyClass>();

public MyClass SomeProperty
{
    get
    {
        return _someProperty.Value;
    }
    set
    {
        _someProperty.Value = value;
    }
}

Answer 1

我假设您想要封装 ThreadLocal<T> ，这样调用者只需要知道 MyClass ;在这种情况下，您仍然需要访问.Value明确地，因为这就是每线程魔法发生的地方:

private readonly ThreadLocal<MyClass> _someProperty = new ThreadLocal<MyClass>();

public MyClass SomeProperty
{
    get { return _someProperty.Value; }
    set { _someProperty.Value = value; }
}
