클래스를 디자인하려고하는데 중첩 된 필드에 액세스 할 때 문제가 발생하며 전체 디자인이 다중 스레드 안전성에 어떤 문제가 있습니다. 나는 이것이 어떻게 설계되어야하는지 또는 어떤 변화가 이루어져야하는지에 대해 더 잘 알고 있는지 알고 싶다.C# MultiThread 안전 클래스 디자인

Boolean checkLocked = deviceInstance.locked;
//Seems like this method for accessing fields might have problems with multithreading
foreach (DeviceGroup dg in system.deviceGroups)
