Question

Can I lock/unlock fields or objects at runtime against writing? In other words something like changing objects to read-only temporarily at runtime…

For example:

int x = 5; // x is 5  
LockObject(x);  
x = 7; // no change  
UnlockObject(x);  
x = 10; // x is 10

if not can you give me some possible solutions?

Answer 1

You can use accessors to do this…

public class X
{
    private bool locked = false;

    private int lockedVar;
    public int LockedVar
    {
        get { return lockedVar; }
        set { if (!locked) lockedVar = value; }
    }

    public void LockObject() { locked = true; }
    public void UnlockObject() { locked = false; }
}
