| Exception | Condition |
|---|---|
| ThreadStateException |
The thread has not been started or is dead. |
| SecurityException |
The caller does not have the appropriate SecurityPermission. |
If the thread is already suspended, this method has no effect.
Caution
|
|---|
|
Do not use the Suspend and Resume methods to synchronize the activities of threads. You have no way of knowing what code a thread is executing when you suspend it. If you suspend a thread while it holds locks during a security permission evaluation, other threads in the AppDomain might be blocked. If you suspend a thread while it is executing a class constructor, other threads in the AppDomain that attempt to use that class are blocked. Deadlocks can occur very easily. |
