例外
仅限 .NET Core 和 .NET 5+ ：在所有情况下。
线程尚未启动或已死。
调用方没有相应的 SecurityPermission。
注解
如果线程已挂起，则此方法不起作用。
Caution
请勿使用 Suspend 和 Resume 方法同步线程的活动。 你无法知道挂起线程时正在执行的代码。 如果在安全权限评估期间暂停线程，则可能会阻止线程中的其他 AppDomain 线程。 如果在执行类构造函数时挂起线程，则尝试使用该类的其他线程 AppDomain 将被阻止。 死锁很容易发生。
在线程上调用 Suspend 该方法时，系统会指出已请求线程挂起，并允许线程执行，直到线程到达安全点，然后再实际暂停线程。 线程的安全点是其执行中的一个点，可以在其中执行垃圾回收。 到达安全点后，运行时将保证挂起的线程不会在托管代码中取得任何进一步进展。 在托管代码外部执行的线程对于垃圾回收始终是安全的，其执行将继续执行，直到它尝试恢复托管代码的执行。
