I have one single datatable object in a static class.

i want multiple threads of different classes themselves to be able to access this datatable through the static classe's single public static property.

i dont think reads are a problem(correct me if I am wrong)
but I am concerned about writes

if it were threads all of the same class type accessing it i could use monitor.enter and monitor.exit
but unfortunatly the threads come from different classes

solutions please?

Use the lock keyword. You could have the database class use the lock. That's one way to do it.

No, do this.

Create a static variable

private static myLock = new Object();


Then where it is potentially dangerous do:

lock(myLock)
{

// code

}
