Do static locks work across different children classes?

Question

If I have

abstract class Parent
{
    static object staticLock = new object();

    public void Method1()
    {
        lock(staticLock)
        {
                   


        

Answer 1

Yes, generally speaking, lock on static objects protect data for all instances of your class.

From MSDN:

Best practice is to define a private object to lock on, or a private static object variable to protect data common to all instances.
