C＃相当于Java的synchronized（abc.class）

Question

I would like to know if there is C# equivalent of the following Java code:

synchronized (abc.class) {
   // code here
}

If there isn't an equivalent, then how can I simulate it in C#?

• abc is a one of my classes in the program.
• abc properties and methods (some of them are static) are accesses by many threads at the same time.

Answer 1

Do not block the class! This may lead to very big problems in your code. Instead, use the lock construct to access static resources from your code:

class Abc
{
    private static object _resource;
    static Abc()
    {
        _resource = new object();
    }

    public static void Method1()
    {
        lock (_resource)
        {
            // this will run for only one thread at a time
        }
    }

    public static void Method2()
    {
        lock (_resource)
        {
            // this will run for only one thread at a time
        }
    }
}

Also, you may use the ReadWriteLock ( Slim ) for your synchronization, if one thread need only to read the resource without writing to it.

Answer 2

To lock the entire class, use the following:

lock (typeof(abc))
{
   // code here
}
